Following your advice, recently I put a Holmes 21T 550 3-pole in ours just like the one in your video and it's a compleatly different beast. Just that one change, changed *everything*. Now it has a real drag brake and excellent slow speed response! We also extended the wheelbase as long as it will go (nice of Redcat to build that capability in without having to change any parts out, just move the existing components to different mount points) to give it a better ride and handling, which worked a treat. Normally I wouldn't be in favour of an extended wheelbase in this kind of truck (look at the deficiencies of the SCX10-III Gladiator!) but in this case, it really is a significant improvement overall. The very first thing we did to our Redcat Gen8 V2 is put an RC4WD Warn 8274 on the stock bumper. It was a little bit of a hassle to make that fit, but it looks great and works even better. A worthwhile upgrade for anyone who wants both scale appearance and scale functionality. We ordered the truck with the Redcat lighting kit, it was only thirty bucks and has a bulb for every light position, it was easy to put in, and it works really well. Compare that to how much it costs to get all the parts for a similar lighting system for a TRX-4. Not bad! Immediately after we got it, I downloaded and printed out all of the little add-on features that Redcat puts out on Thingiverse. Gas cap, door handles, windscreen wipers, liftgate handle, roof rack, and I even did little 3-colour IH man on a tractor badges. Improved the overall appearance of the truck immensely. I haven't put them on yet, but next on the agenda is little scale Warn locking hubs to make the front wheels look better. We have also done the magnetic body mount conversion, and that's been pretty awesome. I don't remember who makes it, but there's a company selling a kit that actually bolts into the fenders, so you don't have to glue them, and never have to worry about them falling out. Worth every penny. Definite improvement over the velcro mounts the thing came with. Those are pretty good... this is just lots better. I didn't want to cut a hole in the body to use the stock spare tire carrier, so we put a metal swing away tire carrier bumper on the back, that looks great and works pretty well too. We're going to have to get a matching metal front bumper to put the winch on to even everything up. Another decent upgrade was swapping those silly Super Swamper stock tires for a set of RC4WD Goodyear Wrangler Duratracs in 4.75" for the stock 1.9" beadlock wheels. That was a great upgrade, those tires work way better than the original tires. And they look a lot better, too. The stock beadlock wheels are just fine and took the new tires with no problems. Lastly, and most recently, we swapped out the Redcat stock transmitter and receiver for a DumbOrc X6DCG 6 channel model with X6FG gyro receiver. That was also a really good upgrade, because it allows us to control the winch from the remote, and provided better steering dual rate, and gives expo on both steering and throttle. We don't really use the gyro, but it didn't cost any extra and I thought it couldn't hurt to have it if we ever needed or wanted it. Having three extra channels gives a lot of opportunity for more options and functions to add in the future (in cabin head control FPV camera, anyone?). With all that, it's not really "stock" anymore, but it sure handles and drives a whole lot better now. We're really happy with the truck, how it drives and performs, the battery life, the features, just everything about it. Great little truck! If the steering servo ever goes out, we'll probably upgrade that instead of replacing it with another stock one, but for now, we have had no problems with the stock one, and no reason to swap it out. It works just fine for our needs. Nothing else on this little truck needs changing. Everything just works the way we want it to.
Wow! That's super inspiring, thanks so much for taking the time to write this! I've just today ordered a light kit for the 2021 Bronco as part of a closer look at the latest TRX4 I'm doing soon. It was ridiculously expensive. Tell you what, your post here is inspiring. I might look into doing all this soon as a further update to the Gen 8 V2. Thank you so much for all the detail! Very much appreciated indeed.
I get a lot of stuff late too. "If it was good then, it's good now", to my mind. There may be better out there, but you sure pay less when you wait for the masses to move on to the next shiny thing! Have fun with it 😎
Bro! This was a great approach on testing! Glad you didn't just slap both in and saved me money. Thank you! I got my gen 8 on the way and this is a very helpful video
@@CrawlersCampRc depends on how steep the hill is. Experiment and see. Also be aware that a 21T 550 motor is still a reasonably fast one for crawling. I suspect you'll find it to be just right in this rig, but you can go higher turn motor, lower gearing or eventually even upgrade the esc to something with stronger drag brake. Start with just the motor and you'll have a basis for future changes. I expect you'll be happy :)
He knows his stuff, I'm a long time fan. His v3 servo in my capra review video is most impressive, too. Love how fast and strong it is. Direct drive from 3S or 4S battery is just such an awesome implementation.
@@RCTNT have you checked out ExocagedRC on RUclips? Great Job here in the states & he brought me into the crawler Hobby & very close with John Holmes & Great supporter as well. I am now into the Engineering of the course building rigs and Riggs and recently started doing some edits and uploads to RUclips myself love all aspects of the hobby. You have a Great thing going!
@@teamsargentrc6399 that's awesome! I kinda withdrew from crawling for a year or two recently with a bit of a mental health struggle so I haven't been up with any crawling channels or anything like that until very recently. I've now watched two or three of Exo's videos (and about the same number from 6 or 7 other channels too) - just to see what people are up to in the hobby these days, for a start. I'm getting back into things again and I'll definitely check out more of his stuff - and yours, why not? We've got so much good stuff available now, it's so crazy. I'm looking at Lesu trucks today, they're pretty amazing.
@@RCTNT It's blown up for sure. Congratulations and overcoming What you've gone through, we all go through tough times in life and how we end up coming out is most important and you look like you have amazing things going for you! Hold & count our Blessing if you will. It's important. So happy to see the better side looking forward to more already.
I bought the HW 2in1 Quicrun Fusion FOC 1800kv, never even tried the stock motor/esc lol. Bought this car to have a crawler about the same size as the trx4 since my sisters husband finally got one after years of my 6,5yo nephew learning to drive on all of my expensive stuff lol..! And I gotta say I freaking love this thing! The HW setup gives you total control and the angles it achieves is stunning considering the price point and the type of vehicle it is. I just need to see if I can shim the diffs to get rid of some rollover in the drivetrain, really the only thing Im going to do to it as of now, its just that good.
First off, thanks so much for your channel. I just got into to RC crawlers and am brand new to the hobby in general and your channel has been so informative. I just ordered this exact RC crawler, aside from the drag brake advantage you get from the motor swap are there any additional advantages gained from swapping the ESC vs the motor? At this point I only want to swap one item so what would be your choice if you considered all factors. Thanks again for the great content 👍
Hey, great! Glad to have helped. In my unit, the motor is the number one first thing to do, and the only thing if you can only do one. (Top Gear Top Tip: it's never only one thing, lol) The motor swap gives you better low speed control, longer battery life (as higher turn motor means lower power but greater torque and lower current consumption) and smoother control. In a few weeks or months, consider doing the ESC and maybe a faster and stronger servo. If you swap to a WP-1080, that ESC gives you more control over config and a better BEC (Battery Eliminator Circuit). I have a full guide on my site for it: rc-tnt.com/how-to/hobbywing-wp-1080-brushed-esc/ Servo swap will give you more strength and speed on steering,particularly if you choose a 7.4v unit and pair the change with a better BEC that can output 7.4V (the WP-1080 does this). Few months after that, look at a little brass and or better tires. I have videos on these things. Look for my Gen 8 V2 playlist. But for now, just swapping the motor is a winning move. Wait until you have driven it a bit before you do anything, though - get used to it before you spend money. It'll be a more informed decision that way. Happy RC trails!
Now you know the secret sauce to wake this truck up, watch how it performs on wet rock against the Sendero HD and the TRX-4 Sport: ruclips.net/video/sSMclXIz96o/видео.html
Thanks for the great video! What an improvement to the truck just from the motor swap. Can I check if the metal pinion gear you used with the HH 21T 550 motor was the stock one from the Redcat motor? Cheeers.
Awesome, I'm glad it helped! There are a few folks here who've not had this problem, so I wonder whether there's some manufacturing variation that's part of this or possibly whether 2S vs 3S might be affecting the outcome. I didn't test with 8v before the change... Did you have the problem on 2S/nimh or 3S lipo?
@@RCTNT that’s interesting I’m using a 2s lipo and before I bought this rc I had a cheaper crawler that actually had better drag brake so I was a bit confused how this one lagged in that department but maybe not all the gen8 have it who knows
@@Eddy_zilla well it's helpful to know you had this on 2s. And from the test in this video I really don't think it's the esc. The data points to the motor being the problem - and since changing to the 21T Holmes, it's had plenty of opportunity to be bad (just see my latest comparison video, for example!) - the esc is up to the job. The motor really just needs a few more turns to be crawler appropriate, I think. Anyway, let the tests continue and we'll learn more as we go! Cheers for the discussion :)
Either your stock motor has a problem or my stock motor is a rather exceptional performer, with power on drag brake at 100% my gen8 V2 does not budge on any incline until it tips and flips over backwards or forward. Maybe the problem yours might have was addressed and repaired on later production runs?? Possibly I just got lucky with mine, who knows..
Interesting. I guess it's possible the motor has a bad wind or weak magnet... Hadn't thought of that. As far as age goes, it's pretty new, I bought it recently as part of my launch plan for the channel. You make a good point, thanks for that.
@@davelaskos1951 quality control could be the issue here. Weak magnets or a bad wind would do it... Though power should be down for such motors too, and my OEM motor had plenty of boogie. I dunno!
Hi, I have had the same experience with the stock motor, also with a HW 1080. But I changed the motor to the exact specs in your video and I still experience the same drag brake problem. Even with all brake settings turned to max drag. Throttle control is a lot better now, but I have never experience this drag brake issue with a HH motor before. Any suggestions?
You're experiencing a weak drag brake with a 21T HH Trailmaster and a WP-1080, is that right? First, double check you've got the settings optimised. I wrote a programming guide for the 1080 here: rc-tnt.com/how-to/hobbywing-wp-1080-brushed-esc/ If still no good, try the stock ESC again, with the drag brake on max. It should work fine, as we found in this video. If that still hasn't helped, your HH motor may be faulty. Try another motor. That's pretty much it for possibilities. One of the above will fix this. I don't know which, but I'd start with WP-1080 programming. Good luck!
@@RCTNT Thank you very much, I appreciate it. Yes, you understood well with the wp-1080 and 21t. I did try all programming options, but with no effect. I'll have to check with the stock esc next and than I'll know more.
There shouldn't be a need as it has a conformal coating treatment from the factory. Replace under warranty or if not under warranty anymore, the wp-1060 is a perfect replacement. It'll be waterproof so you shouldn't have that worry, hopefully!
Hi, just got my Redcat Gen8 V2 and as per your video and recommendation, I purchased a HH 21 turn motor for my car. The motor that was sent to me was a HH 550 27t trailmaster sport. Is this motor OK to use?
Hi, I've installed the new motor, but I still have a problem with the drag brake. With the original motor, mine was like your one, it just rolled down my slope. With the new motor, same slope, it goes very slowly, like really slow crawling speed. Should I go and change the esc to a hobbywing 1080?
If it's better but you still want more brake, then yep, the WP-1080 will do the job. You might try a smaller pinion - unless it already comes with a 9T, I can't recall. That's the smallest. If it's 11 or 12T though, try a 9T. It'll slow it further and give the motor and esc more braking authority over the wheels. It will also slow the rig further, so an ESC with strong braking like the 1080 may still be the better choice here.
Of course, yes, thank you. But that is not available on the stock ESC, nor is it relevant to this test, even with the 1080, because throttle was not applied while it rolled downhill, after that first blip. Freewheeling takes throttle position into account and applies drag brake to the motor at the same time, so you can crawl down a hill at a low speed and retain control. I wasn't using throttle, this was all about just the drag brake :)
@@RCTNT oh ok I got confused because my gen 8 even when stock, had a powerful brake on steep slopes. when I let off the trigger it stopped dead. I got the axe version and put brushed in it and noticed the drag brake isn’t as effective I don’t know why.
@@wildmangeorgesrcchannel6916 I heard some people didn't have the problem I demonstrated here, while others did. I put it down to manufacturing inconsistencies in the motor, but honestly I don't know why some are strong and others are weak! Haven't solved that mystery yet!
I've been going back and catching up on your vids on the Gen8v2. I've changed my esc to the 1080 and yeah it helps alot but I'd like to make it a lil better so I'm thinking about getting the 21t motor. Here's my question (I'm new to crawling) is the 21t any faster than the stock 17t?
Higher turns on brushed motors means slower speed but more torque. Better battery life too. Better control. If you want to go faster, the Gen 8 V2 gears will take it - volt up & gear down. Go to 3S and drop to one less pinion tooth. Ideally grab the 21T 550 motor as well - these three changes will make the Gen8 power train as good as it gets on a budget - and that's pretty good, honestly!
@@RCTNT thanks for the info.. I've got both a 2s and 3s. It's deff fast enough for me on 2s and crazy fast on 3s lol. I wanted to make sure if I went with a 21t it wouldn't be any faster. The low speed control and smoother running is what I was after and now I know.. thanks
Ah, excellent! In this case a 21T 550 (or even a 27T if it's way too fast for your liking) will be just the ticket. Cheap and cheerful upgrade, that! Perfect :)
@@RCTNT hey I have another quick question? If I do change out the motor which is almost a deff I would also like to get a diff steering servo. I'd like to get a good brushless one that is 7.4 volts. Are the HH motors set up for 7.4v also or do I need a bec also?
@@276rclife6 there's some confusion here, but we'll get it cleared up! 1. The motor will take 6v to 14v, generally speaking. 2. The ESC will give the motor the full voltage from the battery (if 2S, that's 8.4v when full; if 3S, it'll supply 12.6v). 3. The servo will have a limit of how much voltage it can take without burning out (commonly 6v, 7.4v, 8.4v and 12v) 4. Modern ESCs include a BEC (battery eliminator circuit) - in the past, you'd have to put 4x AA batteries into the car to power the radio receiver and servo. Now, the ESC includes a power supply that's lower than the battery voltage to power your receiver and servos. So, the stock ESC in the Gen 8 V2 has a 6v BEC. If you put a higher voltage servo in the rig, you'll need to put a bigger BEC in to power it. This is a whole video answer really, but in short, if you put a 7.4v BEC in, you need to make sure you don't let the ESC's own BEC give power to the radio system as well. Typically you'd just remove the red pin from the ESC plug where it connects to the receiver's throttle channel, snugly attaching the loose red wire with tape or heat shrink to the ESC receiver cable. Then plug the BEC wire into a spare receiver port and then your radio and servo will operate at 7.4v or whatever the BEC is rated at.
This and perhaps better tires and steering - per another video in the Gen 8 V2 playlist here! But the motor was easily the biggest thing to get right first, yes!
@@swashbuckler5539 then the motor is just in time! I've got another video on fixing the Gen 8 V2 up a bit that might help. It's in the Gen 8 V2 playlist on the channel. Cheers!

You're experiencing a weak drag brake with a 21T HH Trailmaster and a WP-1080, is that right?
First, double check you've got the settings optimised. I wrote a programming guide for the 1080 here:
rc-tnt.com/how-to/hobbywing-wp-1080-brushed-esc/
If still no good, try the stock ESC again, with the drag brake on max. It should work fine, as we found in this video.
If that still hasn't helped, your HH motor may be faulty. Try another motor.
That's pretty much it for possibilities. One of the above will fix this. I don't know which, but I'd start with WP-1080 programming. Good luck!
@@RCTNT Thank you very much, I appreciate it.
Yes, you understood well with the wp-1080 and 21t. I did try all programming options, but with no effect. I'll have to check with the stock esc next and than I'll know more.
Good luck. HH motor magnets are known to be strong but sometimes things break or aren't as expected. The stock ESC will enlighten you either way!
Anyway to get the esc better waterproofed? I got mine under water for less then 2 sec and it fried it.
There shouldn't be a need as it has a conformal coating treatment from the factory. Replace under warranty or if not under warranty anymore, the wp-1060 is a perfect replacement. It'll be waterproof so you shouldn't have that worry, hopefully!

Nice.
Hi, just got my Redcat Gen8 V2 and as per your video and recommendation, I purchased a HH 21 turn motor for my car. The motor that was sent to me was a HH 550 27t trailmaster sport. Is this motor OK to use?
G'day Peter, it absolutely is. Just means lower top speed, better crawling, better battery life, longer runtime. Install and enjoy that bad boy :)
Thanks, will do
Hi, I've installed the new motor, but I still have a problem with the drag brake. With the original motor, mine was like your one, it just rolled down my slope. With the new motor, same slope, it goes very slowly, like really slow crawling speed. Should I go and change the esc to a hobbywing 1080?
If it's better but you still want more brake, then yep, the WP-1080 will do the job.
You might try a smaller pinion - unless it already comes with a 9T, I can't recall. That's the smallest. If it's 11 or 12T though, try a 9T. It'll slow it further and give the motor and esc more braking authority over the wheels. It will also slow the rig further, so an ESC with strong braking like the 1080 may still be the better choice here.
Do you know about he free wheeling option
Of course, yes, thank you. But that is not available on the stock ESC, nor is it relevant to this test, even with the 1080, because throttle was not applied while it rolled downhill, after that first blip.
Freewheeling takes throttle position into account and applies drag brake to the motor at the same time, so you can crawl down a hill at a low speed and retain control. I wasn't using throttle, this was all about just the drag brake :)
@@RCTNT oh ok I got confused because my gen 8 even when stock, had a powerful brake on steep slopes. when I let off the trigger it stopped dead. I got the axe version and put brushed in it and noticed the drag brake isn’t as effective I don’t know why.
@@wildmangeorgesrcchannel6916 I heard some people didn't have the problem I demonstrated here, while others did. I put it down to manufacturing inconsistencies in the motor, but honestly I don't know why some are strong and others are weak! Haven't solved that mystery yet!
Where did you get the programmer?
Comes with the WP-1080 ESC
I've been going back and catching up on your vids on the Gen8v2. I've changed my esc to the 1080 and yeah it helps alot but I'd like to make it a lil better so I'm thinking about getting the 21t motor. Here's my question (I'm new to crawling) is the 21t any faster than the stock 17t?
Higher turns on brushed motors means slower speed but more torque. Better battery life too. Better control.
If you want to go faster, the Gen 8 V2 gears will take it - volt up & gear down. Go to 3S and drop to one less pinion tooth. Ideally grab the 21T 550 motor as well - these three changes will make the Gen8 power train as good as it gets on a budget - and that's pretty good, honestly!
@@RCTNT thanks for the info.. I've got both a 2s and 3s. It's deff fast enough for me on 2s and crazy fast on 3s lol. I wanted to make sure if I went with a 21t it wouldn't be any faster. The low speed control and smoother running is what I was after and now I know.. thanks
Ah, excellent! In this case a 21T 550 (or even a 27T if it's way too fast for your liking) will be just the ticket. Cheap and cheerful upgrade, that! Perfect :)
@@RCTNT hey I have another quick question? If I do change out the motor which is almost a deff I would also like to get a diff steering servo. I'd like to get a good brushless one that is 7.4 volts. Are the HH motors set up for 7.4v also or do I need a bec also?
@@276rclife6 there's some confusion here, but we'll get it cleared up!
1. The motor will take 6v to 14v, generally speaking.
2. The ESC will give the motor the full voltage from the battery (if 2S, that's 8.4v when full; if 3S, it'll supply 12.6v).
3. The servo will have a limit of how much voltage it can take without burning out (commonly 6v, 7.4v, 8.4v and 12v)
4. Modern ESCs include a BEC (battery eliminator circuit) - in the past, you'd have to put 4x AA batteries into the car to power the radio receiver and servo. Now, the ESC includes a power supply that's lower than the battery voltage to power your receiver and servos.
So, the stock ESC in the Gen 8 V2 has a 6v BEC. If you put a higher voltage servo in the rig, you'll need to put a bigger BEC in to power it.
This is a whole video answer really, but in short, if you put a 7.4v BEC in, you need to make sure you don't let the ESC's own BEC give power to the radio system as well. Typically you'd just remove the red pin from the ESC plug where it connects to the receiver's throttle channel, snugly attaching the loose red wire with tape or heat shrink to the ESC receiver cable. Then plug the BEC wire into a spare receiver port and then your radio and servo will operate at 7.4v or whatever the BEC is rated at.
This will fix the majority of issues you have with any gen8
This and perhaps better tires and steering - per another video in the Gen 8 V2 playlist here! But the motor was easily the biggest thing to get right first, yes!
@@RCTNT yes, just realizing issues with mine after 3 months of major abuse
@@RCTNT starting with upgrading motor, 35kg servo made good change I believe my motor is about to fail
@@swashbuckler5539 they're certainly tough!
@@swashbuckler5539 then the motor is just in time! I've got another video on fixing the Gen 8 V2 up a bit that might help. It's in the Gen 8 V2 playlist on the channel. Cheers!
