Rear Motor Conversion! How to Convert the Redcat RDS RC Drift Car to Rear Motor

[@ezveedub238]

I have a YD-2 SXIII and a RX for my son. After using both, I converted is his RX to a ZX. The rear motor setup is nice, but seems to prefer larger areas for holding a long angle drift on power at speed. It doesn't like fast tight transitions with the pendulum rear weight bias, more so on looser surfaces and the diff lock up or setup needs to be set as well depending on grip. It performed better with lower WT diff oil, going from 10K down to 4-5K oil. Let see how your rear motor setup works soon.

Thanks for your insights! I have been driving this for awhile now - doing great for me!

[@maxrox92]

ahhh i see it was part of the rear motor conversion. i have rough slippery concrete in my basement. it does great but it could totally use more grip. yokomo dra's look sweet anyway

[@RoadsideRC]

Proper shock setup and increasing rear weight are the best ways to increase traction. Avoid the temptation to go to too sticky of a tire, as that doesn't help you learn control.

[@maxrox92]

@RoadsideRC awesome thanks! I'm not sure if it was you but I saw someone suggested switching the front shock oil to 10wt on the stock rds shocks. it seems as though anything more than the the preload nut all the way up and I'm in understeer city. maybe I'm being picky though it really is a joy to drive how it sits.

Hope it does not push in the turns. The driving test video will be interesting to watch. I always enjoy your videos.

[@RoadsideRC]

Thanks Dan! I did a small test drive in my garage. Did just fine! I do need to get it to the track to fully test it though! What I found found with rear-heavy car is they just need a little more throttle to get them to initiate a drift, but otherwise seem to do great.

[@joserifaie]

Cant wait to see the test drive

[@RoadsideRC]

I drove it a small amount in my garage. Felt great. More to come!

[@joserifaie]

Awesome can’t wait

[@westsidemtb3210]

I wonder if Redcat would manufacture a mirror-flipped transmission in the future to make this mod possible without reversing the motor?

[@RoadsideRC]

Interesting idea!

[@westsidemtb3210]

Hey I found the motor reverse sensor solution on another video. Switch the A and C motor wires and also switch the sensor 1 and 3 wires on the sensor cable. Then you’ll have use of the sensor/programming. Also you could install a belt drive from motor to spur and the motor direction can remain as is. kzbin.info/www/bejne/laDQimeNaMR9qdEsi=MrJ4L2u2vAjqY09o

[@SPARTAN1990LIVE]

can you do some videos on the sakura d5 mr and how to get it set up correct ??

[@RoadsideRC]

Maybe! I will need to get a kit to build it! What issue are you having? I have found the stock alignment from the kit to be rather good.

[@SPARTAN1990LIVE]

@@RoadsideRC just the entire car mainly lol but i find your videos super helpfull and easy to understand

[@Neg4Cubing]

I’m looking at getting the d5mr so would also like to see this

[@mikeprater7888]

Im a mid motor guy but i. Glade to see its versatile tho for othe styles

[@RoadsideRC]

It surprised me how easy it was.

[@IowaBudgetRCBashers]

Yes if you reverse the motor rotation, you want zero degrees timing, that’s why with stuff like Clodbuster’s you can’t run advanced timing motors

[@RoadsideRC]

The minimum this ReveD has on the can is 25* - boo!!! I confirmed with Hobbywing that this mid-level XR10 ESC will not reverse rotation - but the next level up does. They also confirmed what you said about the timing.

[@catman25]

Did you ever 3d print that part troy ?

[@RoadsideRC]

I never printed a connector to replace the "waterfall". Honestly, the car seemed to do better with more flex in that area!

[@davidmorales5865]

How u doing I have a redcat blackout I can’t get it to move forward or backwards can u help me any idea

[@RoadsideRC]

Is it brushed or brushless?

[@meirdeaph]

That was cool thanx

[@RoadsideRC]

Happy to help!

[@MakPHL]

What electric screw driver are you using? Ive put together 2 kits and noticed that ive been messing up the threads on the kits with an electric drill.

[@RoadsideRC]

Yes! This is very easy to do if you are not careful! The electric screwdriver itself has been discontinued, but is basically the same as this one: amzn.to/3nHuQ5i The more important part is the drivers. I use these from MIP: amzn.to/3VIUROm Of course, as you found out, it can be easy to strip the heads. Those MIP speed tips will help A LOT. But I also loosen all screws by hand, then use the electric driver.

[@michaelvandenbroader5618]

Does the chassis flex now without the upper brace?

[@RoadsideRC]

A little bit. Not sure if it would be soft enough to notice while driving.

[@dommey2351]

Can you swap a YD2Zs to a rear motor setup?

[@RoadsideRC]

Yes. Yokomo sells the parts needed for the swap.

[@DJ.1001]

I'm curious if you get rear end lift under throttle or if it still squats.

[@RoadsideRC]

Good question! I have driven it just a small amount here in my garage so far and didn't notice. I'll have to do more testing!

[@alphaqgti4054]

When you flip the motor to the other side AND reverse the rotation, the motor will be rotating in the same direction as the original orientation. It will still squat as it did before. Nice RR conversion you discovered. I would want a mechanical connection between the top deck tonthe rear bulkhead somehow. Curious to see what you come up with to eliminate the bending in the middle.

[@Storyracing387]

Wow this is a brain explosion lol nice job 👏

[@RoadsideRC]

Ha! Thanks.

[@kellykuretich6366]
