Hey guys, I picked up a cheap sensorless Hobbywing motor and ESC from Amain. I just tried installing the motor and discovered it doesn't fit! There's nothing in the manual stating any diameter specifics. This is a 540 motor, the edges are a sharp 90deg. so it hits the upper deck, too much to lightly modify the motor or upper deck. I have a 96T spur and a 35T pinion and the space is huge.
I'm gonna have to return it. Is there a specific type of motor I need to order? I now realize I'm gonna need a motor with chamfered edges. I was hoping to do this on a budget to get my feet wet and have some fun, then go with something much nicer later on.

Most motors will have a chamfer on it. If anything it's possible to get away with a bigger spur/pinion combo. What motor turn is it anyways because you're geared at 5.48 FDR? You can run a larger spur for sure, 110/40 may be the ticket.

It's a 4300KV motor. The largest pinion I have is 39T. I only have the 96T spur looks like I'll need a few larger spurs too.

A bigger combo will move everything forward to clear the upper deck.

Yah, I think I'll have to look at a different motor. Just my luck to pick the only motor that doesn't fit! What's a good ratio for quick and fast?

Wish I can help, I don't deal with KV on cars except with boat motors. The gearing you currently have is suitable for a 17.5 boosted or 13.5 motor. My guess is try to get something and fit and take it from there.

That motor should work, just shim between motor and motormount. Should get some clearance. You don't need a new motor yet, try that one first.

forgot to mention, you can space your motor out, i've used this on my Gizmo GZ1 to push the motor out.

I'll give it a shot, seems like I'll have to shim it a lot though. Def. need longer screws too.

Thanks

apologies re suggesting the 9T HW combo. I haven't owned one of those motors since my first entry level RC... and then remember about the manual noting that you need a chamfered motor.

Hi,
With the diff rebuild kit, do I use the large black rubber o-ring to seal the case along with the paper gasket?

cheers
