Hi so far I have got my CF RTR to 102 mph stock tires on wltoys 124016 front rims 4s 3300 mah dumbro 6 channel gyro set about 20% . I changed the top crappy rear a arms to turnbuckles a long time ago.
@@RCTNT With out of the box gears and the gold spur gear I was doing 92 93 mph . After waiting 3 months for parts I put a 45 t pinion gear and the gold spur gear in for 102 mph next I will try the 50 t pinion gear.. I just got a 6000 mah 4 s to try as well I will try the 3300 mah 4 s first half the weight. Good luck to you..
Sounds good! I've optimised gearing already for the speed I want, suiting the motor and all. Just need a wider road! This little driveway is really hard!
Thanks, yeah me too! Harry's rolling out on 16v this morning and all 3 cars are now on foams. Gonna be an interesting morning on this skinny stretch of tar!
I am looking forward to your next effort. I am an old man and a little more cautious than I used to be. You may want to stand up on something so you can't get hit by one of the little rockets. I am sure your next run will be better. The birds were funny.
I finally found some time to watch you video and it did not disappoint. Well done on your first ever speed run attempt! I think it went pretty well and can't wait to see what's next. I wish I had some solid advice to give you as many other commenters have done but I have no experience in high speed vehicles of any sort. (I drive a VW Vanagon. Definitely not fast). Instead I will wish you luck and send positive vibes your way. Take Care!
The Australian winter is as green and lush as a Canadian Prairie summer😂. Love the speed, but that's a funny looking car even though it's based on a real Porsche.
The real car is funny looking too. This seems to be a pretty faithful reproduction. (And winter down south here is certainly lush (that's a code word for 'muddy') but up north and most of the country isn't the same!
17:48 one thing you missed: warm up the tires. Hold it in place on your tail gate and let em spin until you get some smoke.....with the cold pavement you're in a rough situation but it'll help.....
81mph is pretty fast and look’s really fast too. Still a long way to the top but I’m certain you’re up for the challenge. As you know, crawlers are my thing but I have to say this is fun to watch and you seem to be enjoying it too. Looking forward to the next attempt!
I got into cheap speed running recently and found it to be a continuous process of finding and fixing the next limiting factor, which gets really addictive! Like you, I discovered the limits of rubber tires by blowing them apart and wrecking 😂
Great first outing! Does the RC8x have steering and/or throttle speed? It seems like speed plus expo would help. Maybe dual rate too. I've recently discovered how helpful it was to turn down my steering speed on my 4PM in 2wd buggy racing. Looking forward to the next episode!
Can't wait for the next video and hopefully you can get the tires fixed so they can handle the speed and do you think it would help to lower the front a little...I'm just throwing that out there lol...
Front was already low. Rear was bolstered with rubber inside the shock shafts. Suspension is good on both cars, I'm confident. Tires - foams - are the correct answer, yes. I took today seriously and the car rolled a lot better.
I've seen a few videos of speed runs lately and general consensus is to avoid any kind of gyro. You probably already did, but maybe try reducing the dual rate so you have more precision at high speed when turning the wheel. It all looked like a bit of a struggle, but I think there's a lot of potential for improvement, so exciting times ahead. Rooting for you, Craig!
Before I watch...been looking forward to this! And after I watch yay wltoys...I'm a fanboy....but they seem bit more forgiving than rlaarlo in handling from what I've seen looks like the road will hold you back a bit but great first shakedown expected crashes minimal damage nice work buddy cool watching your journey and learning with you.
Nah the gears were all fine. They're still good now. Not a bit of damage there! Got the mesh correct and ratios carefully calculated, all was well on that front at least!
48p gears can take plenty of power, but you've gotta ensure things are shimmed and aligned snugly. These have been fine so far, though in one of the videos in this series I discuss how you could change the gears to 32p or even MOD 1. Cheers
Fair. I am watching it closely as it comes past, ready to jump if I need to. I considered popping the roof rack on and standing on the landcruiser, but these aren't huge cars. I'm pretty sure we'll be good!
Omg that's awesome speed I'm trying to set my up not sure what to run the 3650 motor and 120a esc or team corally kronos motor 825 2050kv any idea please
Yes definitely start with the stock motor and ESC. You can pull impressive speeds with it using stock gear. Just consider buying their upgraded gears so you can get the right ratio to suit the motor. Here's an example I just worked out for you, using some assumptions about gearing, tire size and battery volts, etc.: Pinion gear teeth: 50 (buy their steel one) Spur gear teeth: 52 (the gold one) Transmission ratio: 3 (it's a set ratio in this car) Battery voltage: 12v (3S full charge is 12.6v, so we'll assume some sag under load) Tire diameter: 64mm Motor kV (another constant): 4300kv (I'm pretty sure that's it) Max theoretical speed with these figures: 132mph / 212kph Look on Rlaarlo's site for other pinions and spurs. If you want to go faster, get a bigger pinion and/or a smaller spur gear. With the above setup I suspect the motor will be pushed very hard. I haven't done the maths beyond the basic speed calculation. Be mindful of heat and also see how fast you can go with just the plain stock gearing first. That'll give you a place to start from. I cover this a bit more in the next video - I wish I'd done that myself, first!! It's not overly complex but it certainly isn't easy to get everything 'just so' for a good run. I'm a total newcomer to this stuff so also seek out more experienced people like Raz Shifrin (link in description of this video). Happy tinkering and enjoy the process! Thanks for watching :)
@RCTNT cheers mate I'm having trouble with my streeing servo has you can see in my last video I've just Done for you I need to know the best servo because the one I've got in there is to long the horn touch the front servo saver at the moment any idea be appreciated mate 👍
The potential is definitely there. I must say though that at the high end of competition in crawling, that one mistake here or there has been far more gutting than any high speed crash I've had. I guess the heartbreak is wherever you're most invested.
7:33 billions of dollars in satellites and we're using them to measure how fast our toy cars are lol NASA: all that time and energy so big kids can measure how fast there toys go....arrrgh lol
Great effort Craig! Was that a lipton bushells or a tetleys? Or perhaps an earl grey? Love to see you in a satin, leopard fur cuffed dressing gown for the next run please. And chew gum like a recovering nicotine addict😂...😉
@@RCTNT 😂 Yes, not a bad tasting indian leaf. Mums favourite that one. On the gyro subject. I tend to believe that it is best situated in the rear half to quicker detect rear end movement. But at the end of the day and abit of testing on various rc's.. it comes down to the gyro sensitivity settings.
I dunno about that. Gyroscopic sensor might be best placed dead centre. What you're referring to is something an accelerometer would pick up faster in the rear. Do these things have such a sensor built in? I don't think so. But that could be something we see in future. Certainly it isn't hard to code for those two sensors in the same' package'. Folks have been doing it in Arduino circles for 6+ years at this point!
@@RCTNT I think you misunderstood me. Only talking steering gyro Have a play with its locations if you have the space available. Better tested on drift or 2wd dirt. Higher sensitivity in rear than front. Can be made equally as sensitive/affective usually with the adjustable settings. End of the day its just an angle sensor.

Ooh that's what I needed today. Car was perfect but margin for error just so slim!
Harcore Harry was Rolling ( going fast ) !! At half throttle, can't wait to see that porsche rolling at full throttle!! Great run‼️👍👍🦾🦾
Thanks, yeah me too! Harry's rolling out on 16v this morning and all 3 cars are now on foams. Gonna be an interesting morning on this skinny stretch of tar!

Well done, keep up the good work!
Ha ha, awesome full flip.
Loving the content.
😄
Thanks! Here's hoping I don't have a repeat showing now. Setting up for the serious runs right as I write this
Glad to see you back really missed you love your content x
Good effort 👌 looking forward to the next one 👏
Thanks, me too! Heading back out in about an hour, in fact :) Today's the day!

Well do the CF..... Well.. that's a crash.!
Right.... We'll do the alloy car first....!!! 👍 👍 👍.
I like your style.!!! 👍 👍 👍
haha I'm making lemonade as fast as the lemons are hitting me!!

What a great comment to start my day with. Thank you for the encouragement and for taking the time to leave such a thoughtful comment.
@@RCTNT Considering how many times one of your videos has started my day happily, I am pleased I could return the favour in a small way. Take Care!

Foams today. I'm not too worried about traction. Though if I get it over 100mph this morning, that might change!
@@RCTNT well, when you start pouring on the power you might change your mind when it starts getting squirrely.
81mph is pretty fast and look’s really fast too. Still a long way to the top but I’m certain you’re up for the challenge.
As you know, crawlers are my thing but I have to say this is fun to watch and you seem to be enjoying it too. Looking forward to the next attempt!
Same here. Thanks Scott. I'm just heading out for my next go at it now. Foams are on, batteries are charged!
I got into cheap speed running recently and found it to be a continuous process of finding and fixing the next limiting factor, which gets really addictive! Like you, I discovered the limits of rubber tires by blowing them apart and wrecking 😂
Nice, nice. I noticed these are belted, too. Foams today, we'll see how that goes!
Welcome to the world of speed! 😂 Thought you have done really well so far.
Yeah? Thanks! It feels like a clown show so far but I guess we'll see how today goes on foams!
Can't believe you're actually doing it on those socks wheels. Good luck partner
Eh gotta start somewhere 😅

Thanks, I will check this. I've found it useful on other radios, too. Just got to the road so I'll look in 5. Thanks Andy!

Tires - foams - are the correct answer, yes. I took today seriously and the car rolled a lot better.
I'm sure you'll get everything lined out before the time is up....

Thanks Jorge! Filming now. Same little private road so it's going about as well as you'd expect, but on foams the car is a lot more stable!

I CAN HEAR THOSE DANGEROUS "48 PITCH" GEARS GRINDING.
Nah the gears were all fine. They're still good now. Not a bit of damage there! Got the mesh correct and ratios carefully calculated, all was well on that front at least!
@@RCTNT GOOD DEAL, GOTTA BE VERY CAREFUL WITH THEM BUDDY, THEY'RE SO SMALL, AND FINE.. GOOD VID.

@@RCTNT YEAH, I HAVE A FEW VIDEOS DOING JUST THAT.
I'd stand on a bucket or small item. I would hate to have that smash into my legs.

your 144001 is so cute
Drawing the face gave me a giggle, yeah :)
As I understand Radiolink hs 2 gyro modes✌
Arguably there are 4 given you can invert both settings.

It's just beautiful. People ultimately come back to food, sex and power. Using all this tech for toy cars ia probably a wholesome change for once.
