I noticed they are designed for 1/8 (.125") motor shaft. Most RC motors are 3mm (.118").
Is there anything done to accommodate this .007" difference. If not shimmed I'm assuming the mesh with the spur gear would need to be run a bit looser to accommodate the .007" wobble that would happen.

Or am I overthinking it?

@symmetricon & @EbbTide, thanks...just wanted to make sure before I purchased a few to try out.

You're overthinking, radially that's .0035". I'm sure that's tighter than the tolerance stack up of the parts (spur and pinion and motor shaft).

They fit just fine. Haven't noticed any wobble in them and they spin very true.

I run them in my buggy with a eliminator and have no problems with them. Outside of them not being marked but for the color. But a lil sharpie fixed that.

Actually most 1/10th scale RC motor shafts are 1/8" => 3.17MM. Occasionally people will refer to them as 3MM when comparing them to the 5MM shafts common on the 1/8th scale motors, but they are not 3.0MM.

Well I got my set from Amain today and man they are slim. Looking forward to seeing/hearing the difference

Anyone find they needed to enlarge one of these pinons to fit over the rotor shaft yet? Got some from Amain but they fit very tight and don't slide all the way down on my Fantom v2R 17.5 rotor shaft. Hate to tap it down and not be able to get it back off. Thinking about drilling it out some but wanted to check if anyone else has had to first.

I run the plastic pinions on 2 different Fantom motors and no issue getting them on the motor shaft... The pinion held up fine on my Super Stock 13.5 wheeler with slipper delete.

I'm assuming these are a no go for 6.5 motors!?

I have been running plastic pinions for at least a year and a half. No issues in any of my cars. 17.5 direct drive Losi and AE. XB4 4wd with a 13.5, and AE Stadium truck with a 13.5.

My B6.1 Factory Lite with a Revtech 17.5 Direct Drive, MIP axles with those plastic inserts and MIP outdrives is so quiet you can barely hear it coming down the straight. Everything just seems to run smoother. For me personally being an amateur I have not been able to tell the difference between plastic and metal pinions in 1/10th.

Cant vouch for anything lower than a 13.5. Was told it was not a good idea to go lower

Your not going to gain anything at all by running them, and then your stuck with pinions that are only good for a 17.5.

You’re saving weight and drivetrain weight at that, which is important to most guys. The pinions we usually run for 17.5 aren’t good for anything else regardless of what they’re made of. They’re too big.
