Vhodne pre Trx, na 5mm oskuThe finish of the pinions seams pretty good.
The teeth profile seams good enough to bind with a traxxas 32p spur in (Slash 4x4/ stampede 4x4/Jato/revo/emaxx), however
IMPORTANT the width of the profile is very narrow which means that not all the surface of the spur teeth is used for energy transfer.
This leads to ware.
I do not recommend them for Traxxas Slash 4x4/ Stampede 4x4/Jato/Erevo/Revo/Emaxx/Maxx
