😉👍Gen 8 is ok but nothing beats the trx4! I got a bit more steering by bending the front aluminum rod on mine but that's awesome the radio does add a bit more for sure! I have a Ko propo radio that I use a flysky module in for use for flysky 2.4 I wonder what my Ko pro can do it has loads of adjustments and stuff I may bind it up and give it a go!. Thanks for the test video.
@@RCReviewChannel 😁👍 Your welcome, Man do the mod I did remove that hump on the bottom skid plate of the Gen 8, I just put any size thin steel skid across the bottom I just put up my test video after doing so it ran 100 times better! You will love the Gen 8 after doing so trust me👍 you can also use 4 little flat button top screws to hold it on but I liked the 100% flat method I went with and show because I did this many times on other RC's.
I'm not sure if Redcat made a revision but I just received mine last Wednesday and I got 45.5" right turn and 49" left turn with the stock receiver and transmitter. I measured inside wheel to wheel just as you did. It sill has very touchy throttle.
You keep talking about the turning radius and the steering degree angle compared to the TRX, have you considered if they are the exact same wheel base or not? This affects the turning radius! If the redcat has an even slightly longer wheelbase it will have a larger turning radius! Look into it please!
2:15 you can see the difference between the trx4 steering and the redcat's ackermann steering. Since the outside wheel would trace a larger circle it doesn't turn in as much. This is suppose to negate some binding from the steering axle as both wheels turning circles do not intersect. I added ackermann geometry to my trx6 and it seems to help it turn sharper, but that's an anecdotal observation as I didn't measure the before and after performance.
Just like crawling and off roading in real life, you'll see guys with high dollar rigs that cant make a line, then a guy in a stock 4runner will walk right up. People who thing more expensive is better are just compensating.
Nice work as always, you became my favourite RC reviewer :) Buy the way, your advice will be very appreciated. I currently have Axial SCX10 fully upgraded with metal parts, i use it primarily for crawling/mud bashing, but due to 275mm wheelbase, it struggles a lot on steep hillclimbs. I was dreaming of buying TRX4 Defender with all the technology it offers and upgrading it for super scale trail/competition crawling, but since GEN 8 came out and almost at half price, what would you recommend to get now? only these 2 models are being considered, due to portal axles i love :) Thanks in advance!
@@RCReviewChannel Sometimes seems so, it goes over obstacles better, but when climbing on steep hill even with 65% front weight distribution and low center of gravity it tips back. So do you recommend GEN 8 over TRX4 for crawling/trailing? 150$ difference in price can go straight to good brushless combo or brass portal covers set and good ammout of upgrades. I am asking you because it's not available worldwide yet and you already have good experience testing it :)
Expo should have zero influence on geometry (just how soft the steering feels on center). Does the radio not have adjustable limits? Have you hooked the receiver/servo to a tester?
I'm new to the rc hobby. I have a redcat gen 8 and trying to install the traxxas tqi reciever and transmitter shown in this video. Do you have a video showing how you installed and calibrated the traxxas reciever and transmitter to your Gen 8
0:40 is your tie rod bent or is that the camera lens. My tie rod came straight as an arrow and it bumps the diff cover, preventing me from getting full steering, even with a fully programmable transmitter. Cheers and thanks.
Please help because of this video I purchased a new Traxxas remote just like in the video and receiver hooked it to my gen 8 and yes the steering got tighter but immediately the steering is erratic like interference twitching back and forth and I don't have full throttle it's slower than usual instantly Servo makes whining noise and gets hot
24% improvement over stock. They put the steering capabilities in the chassis but didn't optimize the rest of the system, especially the radio in this case. Fun to solve, thankfully.
Hello !! I have a gen 8 but the end links are touching the tires!! I I checked and are tight its normal in the gen 8 or I have some problems with that ?
Odd mine has no problem getting to that max 47 (not measured but looks 45+). Turning the steering D/R control to the Max seems to work for me. I find it very odd that redcat are going to sell a car stating it does one thing then it not be able to do so because of the transmitter issue? Seems very hard to believe any issue is just down to a transmitter.
Agree!! We have two Gen 8s and both behave the same way. Also we now of several folks that had a the same issue and fixed it with a radio swap. Are you using the stock servo horn?
@@RCReviewChannel please help because of this video I purchased a new Traxxas receiver and transmitter when hooked to my stock gen 8 that causes the steering to erratically twitch and the Servo makes kind of a wiring noise and gets hot and seems I only have about half throttle power immediately unplugged
It is obvious that the trx4 has more percent in making a turn since it has the ability to not use the FWD when you want it with the touch of a button while the gen8 does not come with that system so much that to make a turn with the FDW all the turns are more comprehensive
True but it is not very significant. The Gen 8 has a wheelbase .2 inches longer (12.5 vs. 12.3) than the TRX4. This results in only two more inches in steering diameter results.
.2 is just under 1/4” , which is plenty to dramatically affect turning radius. Add 1/4” to the wheel base of the TRX if it’s not significant and see what happens
@rc hey you do a lot of mods, everyone keeps saying the gen 8’s servo is low and in the way. Has anyone tried to mount it from the top of the chassis instead of bottom mount? Is it possible?
Correct!! We have that data and video somewhere. I believe it's 32 inch circle diameter instead of 38. We find locking/unlocking during technical maneuvers is not quite worth it since the TRX4 already has best in class turning radius.
@@RCReviewChannel well hopefully someone will offer better cvds in the future. Ik the link kit in the works offers the tierod has a double bend to clear the diff cover. And the tie rod get moved below the mounting point, and the drag link connects to the knuckle
Nice work...talk about the issue and than solves it. Your the man!
right on. Issues are just opportunities for hobbyists.
Wow one radio make soo big difference 🤔 and whit it’s that,hi from Costa Rica 🇨🇷🇨🇷🇨🇷🇨🇷🇨🇷

Make me really happy I pulled the trigger on the trx-4 sport
I'm not sure if Redcat made a revision but I just received mine last Wednesday and I got 45.5" right turn and 49" left turn with the stock receiver and transmitter. I measured inside wheel to wheel just as you did. It sill has very touchy throttle.
That is very good to hear. They’ve definitely been making updates. Greasing all the portals now and filling the shocks properly
Could I just order a used Traxxas remote and bind to my stock internals on the Gen8 ?
Mine wasn’t maxed out oddly enough. Seems to be doing fine. I have a new servo though as well not sure if that comes into play or not.
Servo might be a fix if a servo has more throw than stock

trx4 still out here crushing it!!
King crusher!!
Idk my gen8 keeps up with sports pretty well. It's all on driver skills

I noticed when the wheels turned the axle was shifting off center is the panhard bar geometry messed up and not holding the axle

What does that mean? Wheelbase is too short for very steep climbs? Longer is better?

Sorry, not steering expo but steering rate, or range. Completely maxed out on stock transmitter and cannot hit limits.

Hi always cool vids. Did you have any fix for gen 8 inner tire rub on the steering assembly?
I upgraded to 25kg hexfly and heavy links up front w stock radio. So much range it’ll prob break the front axles if I’d max it out on the controller.
What an improvement,,,
24% improvement over stock. They put the steering capabilities in the chassis but didn't optimize the rest of the system, especially the radio in this case. Fun to solve, thankfully.
👍 just ordered a fly sky gt5

@@RCReviewChannel stock everything at the minute. I'll do a few trail runs before any mods. Tires seem very 'slick' when wet.
Good stuff
My Redcat Gen7 on portal axles, makes a U-turn in 31inch.
Sup, Francis? How about a review on the Transition Scout carbon? hehe!
Francis is that cogging bad can that destroy the cv joint or whatever there called in the axles/wheels? Thanks
Right. Never apply full power when it's cogging like that.
@@RCReviewChannel Thanks 👍🏻

Good job but I’ll stick with my trx4. At least till there’s a used 1 on eBay.
Nice
Doesn't the gen 8 have a longer wheelbase? That would result in less turning also.
True but it is not very significant. The Gen 8 has a wheelbase .2 inches longer (12.5 vs. 12.3) than the TRX4. This results in only two more inches in steering diameter results.
@@RCReviewChannel ic ic, they are both awesome trucks, keep up the great work 🙂👍

@@adamsmith2400 I thought so two👍 big difference in wheelbase, therefore, gen 8 has wider turns.
The difference is very small. We have a TRX4 Defender with an even longer wheelbase and its turning radius is much tighter than the Gen 8.
@rc hey you do a lot of mods, everyone keeps saying the gen 8’s servo is low and in the way. Has anyone tried to mount it from the top of the chassis instead of bottom mount? Is it possible?
Not possible, unfortunately. Very tight in there.
Do you have any stickers one can get from you!!
Changing the transmitter also improves the throttle modulation of the awesome Redcat Gen 8. It is shown here th-cam.com/video/aLbw1DsC1DI/w-d-xo.html
My God, a Trx-4 with unlocked diffs would be even better than the sport, no? 😱😱😱
Correct!! We have that data and video somewhere. I believe it's 32 inch circle diameter instead of 38. We find locking/unlocking during technical maneuvers is not quite worth it since the TRX4 already has best in class turning radius.
Now install some in the works rc steering links n I bet it will make a even better difference
Will look in to it. The CVDs though are severely stressed at the extremes and are limiting range and power delivery.
@@RCReviewChannel well hopefully someone will offer better cvds in the future. Ik the link kit in the works offers the tierod has a double bend to clear the diff cover. And the tie rod get moved below the mounting point, and the drag link connects to the knuckle
Does anyone know if the v2 fixed this issue?
Have you heard if they fixed this issue with the v2?
Traxxas is just a fucking brand name if the redcat was named a Traxxas people wouldn't be talking shit
That gear mesh sounds terrible
Good ear. We will check that. Too loose or too tight?
