8mm pinion problems

[Mattyd926]

Is there a motor mount insert for the arrma v4 mount that is thinner so I can fit my pinion only a 21 tooth but the pinion is huge

After seeing not responses I figured I Would be more specific. I installed my Tp motor 8mm shaft . Since the shaft is fatter the pinion will not sit in the hole in the mount so I tried flipping the pinion but I’m barely grabbing the shaft with the grub screw. It seems like I need a pinion thatS skinnier In the gear section.? I was thinking of grinding down the pinion . Please help !!

Which motor mount are you using? Maybe this one using the 1/5 scale version will work. https://practicalproto.com/products/v4mount
@PPS-RC can let you know.

Saga saves the day. I’m not sure what these fools sent me but it wasn’t what I needed. Ordered a saga 21t 8mm and it fits like a glove.
