Fit perfectly in lmt. Other brand pinion gears dont mesh correctly but this one does.

Solid so far. Using this in the Ryft with the Castle 1415 5mm motor. It's holding up perfectly. Use a little lock tight.

Attempted to use on rival MT8. Upon tightening with hand-tool, gear broke in half... I was not using an Allen wrench or anything, just a normal MIP hand driver. I think the material is to thin.

What reviewers say

Three verified owners reviewed this Mod1 5mm bore pinion gear across 16T, 15T and 10T variants. Two reviewers, using the 16T and 15T in an LMT and a Ryft with a Castle 1415 motor, report good mesh and durability, with one suggesting threadlock. One reviewer using the 10T variant in a rival MT8 reported the gear cracked in half while tightening with a standard hand driver, and attributed this to thin material. Reviews are few and cover different tooth counts, so evidence on the 10T variant rests on a single report.

  • + Good mesh with Losi LMT
  • + Holds up well in Ryft with Castle 1415 motor
  • − Gear cracked when tightened with hand driver (10T variant)
  • − Reviewer suspects thin material
