4 pole brushless with 5mm output shaft

Anyone run anything like this here? I have one I plan on using for a bouncer setup and having trouble getting a spur gear/ pinion setup. It's a 550 3500kv

What are you having trouble with? 5mm 32p pinions go down to like 9t.

RRP has always been my go to pinion, the standard set screw is annoying though.


And I was wrong, they stop at 11t. 11/64 or so will be plenty slow, 12/60 ish is pretty good at 3500kv.

It will be a dual purpose rig, it will see some time at a short course track as well, 12/60 will still be good enough with the gear reduction from the driveline?

Set aside a small chunk of change if you plan on running a Wraith on the track. You will break, constantly.

I bailed on the go fast wraith, went to a bomber. I still break it every time out, but not nearly as bad as the wraith.

Short wheel base with locked solid axles and more power/speed than needed doesn't end well. Lots of fun, but doesn't end well.

It's not technically a wraith... it's got a wraith skid and trans. IFS front suspension with unlocked dif and vaterra koh rear axle. Just posted in here due to what I'm using for driveline

5mm motor shafts are THE way to go. The smaller 3mm shafts can break under stupid usage. Been there.


I've seen 32 pitch 5mm down to 10 tooth from someone at one point but 11 tooth Robinson is readily available.

Well that's better. I would go considerably faster, 14/56 or so and check for heat.
