Every time i watch one of your videos, I want to go out and DO RC! there is a lot of interesting engineering, such as the floating disc. I've never had an RC bike, but the Losi design and excellent performance had me convinced.
i love treal parts, i know they are a cheaper Chinese manufacture but i have had REALLY good luck on their fitment and machining tends to be great for the price.
Yeah I haven't really had any problems with any of their parts. It's a testament to their quality that throughout the entire build process I didn't have to modify a single thing.
Absolutely beautiful video, brou. from spending 30-40 years racing motocross this rig was right up my alley. i haven't put to much upgrade to it other than swingarm and linkages. some day ill do what you did. maybe this winter. awesome video "Do". i learned a few things. have fun.
12:59 the amount of golden nuggets you drop in these videos is kind of insane. How else would one know to use dry lube on a servo saver? Edit 14:56 I never even thought about threadlocker dripping into bearings!!
I haven’t done any research on batteries yet, I’ve had my bike since Christmas. The stock battery lasts like 3min on the sand 😮💨 but I love this thing it’s such a head turner
Definitely a tank of a promoto 👍 Those CF wheels are so nice 🤩 If I ever get one of these I think the wheels would be my only upgrade. This bike is so complex! Im sure you learned alot by building it this way.
"That's quite a beautiful machine you have there! I really like what you've done with it! I think the ultimate evolution for this model would be to automate the pilot, so it could use its foot for support instead of the fixed stabilizers. But with even the slightest crash, bye-bye automation, haha. In any case, if I had this model, I’d go for this project. About drive, I think the best way to improve stability is to remove the anti-crash system, which makes the steering feel soft. But I'm not an expert."
Cool vid, thank you. This is the reason I haven't bought a Promoto yet.. I know I would buy all those upgrades and end up with a small fortune in it. Like all my other RC stuff.
I would have left the inner piece off as well instead of ripping back apart. Then it woukd bug me for 2 weeks before I take it completely back apart and put it on in the end. Lol hopefully you're at terms with your decision. Awesome build man. I'm so close to ordering one. Just got the losi db pro after the dbxl and really happy with the losi quality and build.
I use a lot of alloy wheels on my touring cars & you'll find it adheres well enough, but not as well as plastic rims. It won't stay glued as long, you'll really need to get into the habit of checking your glue bead regularly & redoing it from time to time.!
I've given mine a flogging Apart from a few part's like that front plate that breaks and the linkages. Replacing the plastic part's is a back step. Plastic bends and goes back to shape. Metal bends breaks. And plastic is lighter. The bike's heavy as it is. More weight means less performance.
Yeah a build like this isn't necessarily designed to create the most efficient end result. This is an extreme upgrade mostly just to showcase what can be done. I would not really recommend anybody do this unless their goal is to have the most upgraded promoto :-)
That's definitely the most mods I've seen on one. You gotta at least give a ballpark on what this cost. Talbot put $900 in upgrades on his if i remember correctly and didn't go nearly as deep. How many rtr ones could you buy for this total amount? It looks great regardless. I've never wanted the Promoto but I've almost bought a RZR Rey a few times. I just wish it was bigger. I think a SBR 2.0 sized RZR Rey would be a lot of fun.
gluing on aluminum usuallly gives way which is why most aluminum wheels are beadlocks but in this case seems to work just fine. overall this bike build looks great I wonder if they will sell aftermarket panels that you can paint as if this entire bike would look cool all black.
Bro!! What a PERFECT pro-moto build!! Holy moly brother… I can totally tell that your bike out handles the sh!t out of the stock PM. A cool running video, on the right terrain, would be awesome with that bike. Let me know if you’re ever selling it… I’ll buy it with no BS👍🏻
@@DoRC hey brother, I just got a chance to drive the pro-moto that my buddy has. As much as I want one of your AWESOME builds. I now don’t want to waste this opportunity to get one of your RC’s when I don’t like the pro-moto after driving it. I put 4 packs through it… I just don’t like it. So, I am going to wait till you build something awesome on four wheels that I fall in love with to bug you about buying it. Is that cool?
I tried all aluminum with my Promoto a big mistake; bike too heavy, slow, started breaking parts. I put it back to stock and added a Reefs 99 micro servo for better brakes. It does stoppies on a fly.
@@DoRC check out Earl M. He upgraded the power system on one. He used a BEC to restrict voltage to the gyro and then upgraded the drive motor & ESC. He was trying to hit 100 mph. If I remember correctly he made it up into the 70 plus mph
Yeah I've had it both ways. Sometimes it's okay and sometimes it ends up causing enough flex to actually mess up the gears. In this case it seems fine.
what is the diameter and the length of the Swing Arm Layshaft, the shaft that doubles as the linkage for the swing arm and as the final output shaft of the transmission? It looks like a 5mm shaft on it, but i am only speculating. I'm working on converting a large scale New Bright 4 wheeler, and i want to move it to a solid rear axle and a chain drive. also, what is the distance between the center of that shaft and the center of the rear wheel axle? I'm curious if the chain for the stock or the 30mm extended swing arm will be long enough for me to use on my project.
@@DoRC the sprockets and chain will work perfectly for me on my conversion. Now I need to buy some parts and start designing some others. Thanks again for that information.
Do you know if i could set this bike up to work with my flysky nb4 plus transmitter?that question has been the only thing stopping me from buying one of these.
Maybe. The receiver does use an internal gyro for stability I honestly don't know if the gyro on another receiver would work or not. Everything else would work though.
Why did you put the front brake and leading axil on backwards? you now have a trailing Axil (*wrong rake) and the caliper is out front?. Was this a suggestion from Treal i didnt hear it mentioned in the video. Thx
Good grief.!!! How much did that cost you.??? I mean, the stock ones aren't exactly cheap so that beauty must've set you back an arm, a leg & your danglies.!!! It's extremely impressive & I love seeing it, but I could never justify spending that kind of money on an RC.! Thank you for sharing.
The brake caliper on the wrong side gave me the idea of running dual front calipers but you'd have to run both cables on the same servo. I've seen it done on custom mountain bikes
If you want to test an alternative to your nocry driver, Amazon basics USBC screwdriver it has an electronic clutch and I’ve found it to be soft enough for many plastics, but it’s also a better handle for manual driving the last mm with.
@@DoRC well on max torque it removed the motor mount screws on my xo-1 as if they weren’t even tight, and I know I had those locked down well. The Xmaxx and xrt haven’t needed any work since I got it, but based on what I have done with it I highly doubt there’s a single screw on it that this won’t remove. Pretty sure I also used it on an orange thread locked grub screw somewhere as well.
@@DoRC I considered it to be an upgrade from The $125 Dewalt I used to have. Neither ran out of torque but the gyro actuator was just stupidly annoying in a lot of places
Thank you for sharing this video. I would be delighted to make a donation if possible. I am new to the RC Motorcycle hobby and have been unable to fully enjoy my Promoto due to some unforeseen circumstances. When I pre-ordered the bike and upgrades from the Losi/Horizon website, it did not include any of bike upgrades and electronics I had expected. Additionally, their website did not provide clear information about what was included in the shipment, and the bike arrived separately. As a result, I have only been able to take it out of the box and turn it on.
I appreciate the offer but I don't do this channel for profit. It's not even monetized so no need for donations. As far as what came with it what exactly is missing?
@DoRC Nothing is missing on PromotoMX! I purchased aftermarket parts for PromotoMX and they were on backorder for months. I called Losi to cancel the order. Sorry for the confusion!
You'd be surprised about c rating. It's pretty much always a lie and there really is no such thing as a 100 c battery. I recommend just going with a good quality brand such as SMC. You're going to get the best performance out of something like that even if the label doesn't have the highest c rating.
16:42 The fork is like that? I mean at the steering column, it looks like you built it the wrong way no ? On a real bike the two “T” plates (holding the fork tubes) are not mounted like that but the other way, the fork tubes must be in front of the steering column, not behind… (Hope my English is understandable 😭)
Burping the throttle is actually a bad Idea...you go from traction to loss of, and back to traction...repeat. I too have this machine, smooth throttle wins races and holds considerably more traction.
That did not look fun to drive on that terrain. It would have been good to take make a springs/oil adjustment to see if that's the problem, or if there's another issue. I'm left not knowing if the problem is with settings, Losi, or all the aftermerket parts.
It actually was pretty fun. I think the terrain just was too much for the bike. I'm not sure you would be able to tune it to be able to handle that smoothly.
Most upgraded 🤣. The glue needed on alloy to rubber is Loctite 480. The full size AGFrc is a perfect fit the one you had needs some spacers and two of the slots extending slightly. No damping fluid in the headstock. There are upgraded drive sprockets but Vitavon not Treal so I guess you ignored them as not the sponsor. The silver and black springs are the same weight one is wound left the other right so twisting cancels itself out the center part rotates with travel.
According to the MDS loctite 480 is CA glue with rubber in it. Might be more appropriate for this particular application but standard CA glue is rated for gluing rubber to aluminum. That's cool. I didn't have the full size AGFRC servo so wasn't really something I could test during the build. I'm sure there are plenty of servos That fit though. I did a quick search before the build and didn't see any sprockets but sometimes the vitavon stuff can be difficult to find The Black springs have a smaller wire diameter than the silver ones so at least by my measurements they are not as stiff. It may be a small enough difference is to not matter but at least again by my measurements there is a difference. Thanks for watching :-)
Technical jargon - springs absorb shocks. The thing with the oil and pistons dampen the oscillations of the spring. This is why certain people correctly refer to them as dampeners instead of shock absorbers. Don't get me started on the differences between struts and "shocks." They are different things!! Hinit - the Losi has front struts while the rear (and tiny 3rd front) "shock" is merely a dampener.
Looks cool but when some Tamiya quality rallye rc car in 1/10 and full tuning, anything like this in plans? Tamiya is picky and their plastics can cut skin...and their shocks are a joke...
The number of coils in a spring can be used to compare stiffness if using the same brand of springs from a manufacturer that only uses one spring material to make all of their springs. This ignores things like progressive vs linear and dead coils that merely affect ride height. 6 drumsticks from KFC is a lot more chicken than 10 McNuggets from McDonalds but is a lot less chicken than 5 chicken breasts from KFC.
Correct. If you watch the video you'll see that before I start counting coils I measure the diameter of the wire and ensure that the wire is the same diameter on all of the springs I'm comparing.
It's kind of hard to drive it fast in rough terrain but it is capable of going quite a bit more quickly than you saw in the video. According to the manual the chain should be as tight as you can get it without binding. My chains actually a little bit looser than that.
I'd have to measure it but I suspect that the wheels actually aren't any lighter. The stock ones are plastic and these are aluminum and carbon fiber so it's probably pretty similar.
Overkill bigtime . Handling dropped dramatically you can see that in the video. All this aluminum stuff is nice but it definitely does not increase the handling at all at any point the bike was designed and developed for six years to be able to perform the way it does adding weight does not help. Maybe a little bit in the key areas as far as the lower center of mass. but now the gyro has to work twice as hard to keep all that weight stood up you can see it when you turn the bike it kept on the wobble. you might be able to adjust a little bit of that out with the gyro but again it's worth doing twice the work that it was not intended to do. you can also hear the motor over reving .. i bet temps where high Don't get me wrong this makes the bike look killer, but you're basically built a paperweight or parking lot pounder. most of these add on are for aesthetic purposes.
Where as this build was done more as a showpiece than a practical piece There are some things I don't fully agree with. First of all stability actually is reduced the lower the center of gravity on two wheeled machine. The more weight you have up high the more inertia it has so the less tendency it has to change direction. As far as it wobbling around that was actually me not the bike. I'm not that familiar with driving these and trying to drive film and do things like jump really aren't easy. The bike itself was actually pretty darn stable. Didn't really notice any issues with temps either as it really isn't that much heavier than the stock bike as I showed when I weighed it. Overall I would definitely not recommend all of these upgrades to someone as like you said most of them aren't actually necessary but I don't think it really changed the dynamics of the bike as much as you would assume.
Ha ha, really ? The first time I didn't believe in counter steering, I turned the handlebars left and the motorcycle went right.....into a wooden fence. But I guess there's still folks clinging to the flat earth idea, and Christian Scientists, and Scientologists. People are dumb, but driving into a fence was enough for me (this time).
You injection molded the plastic and machined the metal to fabricate an RC moto from your own design? Your RC "from scratch" needs to be entered into competitions. Are there RC car competition for scratch builders like in the RC plane industry (look up Top Gun competition) where people build planes of their own design by taking or using pictures of full sized planes or plans?
@@Rckid28 true but I've done dozens of builds over the years and it's usually pretty easy to tell Right away if something is overweight. Again it's only 15% so it's not a massive increase.
Not quite. He didn't install the upgraded wheels, chassis, shock spring, fork springs, gears, battery box etc. He definitely had a lot of upgrades but as far as I know mine is the most upgraded one at least on RUclips :-)
This is the coolest promoto build I’ve ever seen man you killed it 🤘🏽 what an absolutely epic bike build!

Edit 14:56 I never even thought about threadlocker dripping into bearings!!
Yeah it's something that you need to be aware for bearings as well as things like kingpin pivots. I've seized up kingpins before with threadlocker.
I'm consistently impressed by the effort you put into your videos. I don't know how you put out so many at this level of quality.
I'm glad you enjoy. I do it for you guys so keep watching and I'll keep making them :-)
Alcohol to clean threads is a must in a rc helicopter! Bearing retaining compound would be great to use for the bearings in steering stem!
Yeah if it's an important screw it's definitely best to clean it.

I'm tempted, but it seems too big. But it is clear to me that one will have a lot of fun with it.
That’s what she said
It is a big bike but to be honest with you I wouldn't want to go much smaller just because of the terrain you would be limited to.
Dude! you nailed it that looks friggin cool.. nice1 n that

Nice job man that thing is awesome thanks for another great video 👍😎

Great video. Really seems like a lot of time to put that together not sure I’m that patient to wait cause Id want to drive it asap.
Yeah it was probably about 20 hours total build time though I might have been able to do it more quickly if I wasn't filming.
It's always worth it. RTR's are nowhere near most kit builds as far as performance just like real autos and motos. Take the plunge lol

(Hope my English is understandable 😭)
Yes that is the way it's set up on the promoto. The triple trees are reversed from what you would expect on some bikes
We need a Japanese sport bike and an American cruiser now
That would be cool!
Burping the throttle is actually a bad Idea...you go from traction to loss of, and back to traction...repeat. I too have this machine, smooth throttle wins races and holds considerably more traction.
You're absolutely right. It's a really bad habit from many years of bashing.
wish you could purchase the bike with all the upgrades!!!
That would be sweet. I'm sure somebody would be happy to do the upgrades for you but it probably wouldn't be cheap.
600/700 dollar bike, what is the total now ??? curious
Around triple that
Do have a link for the springs for the shocks ??
I believe I got them on eBay. If you go on there and search for promoto springs you should be able to find them
@@DoRC thank you .
I just bought the Promoto for myself . It was hard to find different springs until I watched your video .
@@jamesbeyor6180 Yeah there are a few options available though like I said in the video it seems like most of them are actually softer not stiffer
That did not look fun to drive on that terrain. It would have been good to take make a springs/oil adjustment to see if that's the problem, or if there's another issue. I'm left not knowing if the problem is with settings, Losi, or all the aftermerket parts.
It actually was pretty fun. I think the terrain just was too much for the bike. I'm not sure you would be able to tune it to be able to handle that smoothly.
The head dampener is supposed to be filled with 500k diff oil
Ah. Well I didn't really notice any negative effects the way I had it maybe the extra mass of everything effectively damps the motion
@@DoRC the oil damping the steering.
Pro moto is a new dieing bread! Hahaha 😅😅😅 I wouldn't touch that with a 10 foot pole
Why not?
@@DoRC I will tell ya. Ypu can't race them like we do buggies, Handles like shit, Drives like crap unless going straight! Junk
Is this a case of "if you ask how much it costs you can not afford it"?
Maybe. All of the upgrade parts would be about $1,300
@@DoRC Thanks. All I was trying to say it would be nice if you mentioned it in the video.
My biggest issue with this bike. Is ... The driver flopping around lol. Fix this and ill buy one.
There's a 3D printable piece you can either make yourself or buy that goes between the torso and the legs which reduces that tendency.
MAN, YOU PUT THE FORKS BACKWARDS
Yep. I fix it later in the video :-)
Rear spring is too heavy. Drop it down one
It might just be too much preload. I had it cranked down pretty hard
11:26 come on man get your info right… there sure is an upgraded sprocket
I didn't find one.
@@DoRC you didn’t look hard enough 😂🤣
@@Rckid28 apparently not :-) thanks for watching!
Most upgraded 🤣. The glue needed on alloy to rubber is Loctite 480. The full size AGFrc is a perfect fit the one you had needs some spacers and two of the slots extending slightly. No damping fluid in the headstock. There are upgraded drive sprockets but Vitavon not Treal so I guess you ignored them as not the sponsor. The silver and black springs are the same weight one is wound left the other right so twisting cancels itself out the center part rotates with travel.
According to the MDS loctite 480 is CA glue with rubber in it. Might be more appropriate for this particular application but standard CA glue is rated for gluing rubber to aluminum.
That's cool. I didn't have the full size AGFRC servo so wasn't really something I could test during the build. I'm sure there are plenty of servos That fit though.
I did a quick search before the build and didn't see any sprockets but sometimes the vitavon stuff can be difficult to find
The Black springs have a smaller wire diameter than the silver ones so at least by my measurements they are not as stiff. It may be a small enough difference is to not matter but at least again by my measurements there is a difference.
Thanks for watching :-)
. . . . . .and $18,000 later 🤣
Move the comma to the left once and you're pretty close :-)
Technical jargon - springs absorb shocks. The thing with the oil and pistons dampen the oscillations of the spring. This is why certain people correctly refer to them as dampeners instead of shock absorbers.
Don't get me started on the differences between struts and "shocks." They are different things!! Hinit - the Losi has front struts while the rear (and tiny 3rd front) "shock" is merely a dampener.
Damper, not dampener
as well
Thanks for the info :-)
Looks cool but when some Tamiya quality rallye rc car in 1/10 and full tuning, anything like this in plans?
Tamiya is picky and their plastics can cut skin...and their shocks are a joke...
I don't really know a lot about Tamiya but definitely something I would like to try!
The number of coils in a spring can be used to compare stiffness if using the same brand of springs from a manufacturer that only uses one spring material to make all of their springs. This ignores things like progressive vs linear and dead coils that merely affect ride height.
6 drumsticks from KFC is a lot more chicken than 10 McNuggets from McDonalds but is a lot less chicken than 5 chicken breasts from KFC.
Correct. If you watch the video you'll see that before I start counting coils I measure the diameter of the wire and ensure that the wire is the same diameter on all of the springs I'm comparing.
Looked very slow tvf and the chain was to tight
It's kind of hard to drive it fast in rough terrain but it is capable of going quite a bit more quickly than you saw in the video.
According to the manual the chain should be as tight as you can get it without binding. My chains actually a little bit looser than that.
The reduced unsprung mass from the carbon wheels could mean that the suspension needs retuning.
I'd have to measure it but I suspect that the wheels actually aren't any lighter. The stock ones are plastic and these are aluminum and carbon fiber so it's probably pretty similar.
Overkill bigtime . Handling dropped dramatically you can see that in the video. All this aluminum stuff is nice but it definitely does not increase the handling at all at any point the bike was designed and developed for six years to be able to perform the way it does adding weight does not help. Maybe a little bit in the key areas as far as the lower center of mass. but now the gyro has to work twice as hard to keep all that weight stood up you can see it when you turn the bike it kept on the wobble. you might be able to adjust a little bit of that out with the gyro but again it's worth doing twice the work that it was not intended to do. you can also hear the motor over reving .. i bet temps where high
Don't get me wrong this makes the bike look killer, but you're basically built a paperweight or parking lot pounder. most of these add on are for aesthetic purposes.
Where as this build was done more as a showpiece than a practical piece There are some things I don't fully agree with. First of all stability actually is reduced the lower the center of gravity on two wheeled machine. The more weight you have up high the more inertia it has so the less tendency it has to change direction. As far as it wobbling around that was actually me not the bike. I'm not that familiar with driving these and trying to drive film and do things like jump really aren't easy. The bike itself was actually pretty darn stable.
Didn't really notice any issues with temps either as it really isn't that much heavier than the stock bike as I showed when I weighed it.
Overall I would definitely not recommend all of these upgrades to someone as like you said most of them aren't actually necessary but I don't think it really changed the dynamics of the bike as much as you would assume.
There are too many motorcyclist that "don't believe in" countersteering. 😮
It's all about the physics :-)
Ha ha, really ?
The first time I didn't believe in counter steering, I turned the handlebars left and the motorcycle went right.....into a wooden fence.
But I guess there's still folks clinging to the flat earth idea, and Christian Scientists, and Scientologists.
People are dumb, but driving into a fence was enough for me (this time).
And once again, you ruin the video with music 🤦
Thanks for your feedback!
You injection molded the plastic and machined the metal to fabricate an RC moto from your own design? Your RC "from scratch" needs to be entered into competitions. Are there RC car competition for scratch builders like in the RC plane industry (look up Top Gun competition) where people build planes of their own design by taking or using pictures of full sized planes or plans?
In this case from scratch means Not starting from a completely built one and just upgrading it. I apologize for the misunderstanding :-)
Not every title can be as accurate as yours. Is it a lot of effort fulfilling the name so perfectly or does it just come naturally?
He could definitely build a winner. I know it
@@DoRCand I thought he was being sarcastic 😅
It's entirely possible. I do have some equipment coming that's going to let me scratch build things pretty soon though :-)
More like a downgrade with all that weight…
It's really not that much extra weight. I don't know if you saw the end of the video but it's only about an extra 15%.
@@DoRC just more stress on battery’s… I know as I built a bike from scratch when they first came out
Yeah it's more stress on everything but I personally haven't experienced any problems related to the extra weight.
@@DoRC makes sense considering you just built it 😂🤣
@@Rckid28 true but I've done dozens of builds over the years and it's usually pretty easy to tell Right away if something is overweight. Again it's only 15% so it's not a massive increase.
"Not a bad way to spend $10,000 dollars"! IYKYK
:)
chek kevin talbots promoto is has all the upgrades well befor you nice try liar 😂😂😂
Not quite. He didn't install the upgraded wheels, chassis, shock spring, fork springs, gears, battery box etc. He definitely had a lot of upgrades but as far as I know mine is the most upgraded one at least on RUclips :-)
🤘🏼🤘🏼
Thanks for watching :-)
