Electronic center "diff" Revo Conversion

[Maciolus]

You should also consider differenciating drag brake setting between front and rear motor.

Great project. Lot of work and setting. I keep my fingers crossed!

Good point. If only CC had an RPM limiter built into their software... Hopefully with the rear having more punch control, wheelies won't be an issue. Although a torque limiting setting would be ideal since punch control will limit mid-air control.

It will be a lot of work to get it set up properly, so I too am hoping it will work well! (otherwise it'd be somewhat of a waste of time/money).

One current concern of mine is the strength of the stock diffs. Sike has been having issues even with the Hot Bodies 10/43 diffs (or at least the bearings). I might have to try out the buggy diff conversion, which could actually help because then I could use a smaller motor with a higher kv (it's been difficult finding a motor with ~500 kv, that's not too big).

For the stock Revo diffs, here's what I'm looking at for two motors:

I work there, so I should be able to get both motors for ~$100. On 5s A123 and the stock diff ratio (37/13), it should reach ~45mph, which is perfect for beating the nitros.
If I were to switch to buggy diffs (43/13), a motor of ~540 kv would be suitable, as would a motor of ~610kv for the truggy diffs (43/10)

Possibly the R1Pro speed control would be usefull. I understand that it has a current limiter built into it rather than just a spool up timer like the CC controlers. A current limiter would act very similar to a torque control limiter.

Actually the current limiter is the reason I really want to try the R1Pro in one of my buggies. I think it could be much more effective at dialing in the power for optimum traction.

Sounds interesting to say the least!
I've always pondered using a motor per wheel with a slipper on each motor as a sort of "slip diff", but this idea sounds much more involved. Can't wait to see it how it'd function.

I'm familiar with that feature of the R1 Pro. Unfortunately, it is much too expensive, especially for me to use two of them.

Only potential problem I see with the "slip diff" is it not being able to handle enough torque. But if that could be worked around, then it should work great.
