Revo - 4s 9XL

[BrianG]

The stock internal gears are holding up very well after numerous runs in my Revo, so I don't know if it would be worth it to switch to the metal gears IMO. I don't see why the Jato pin mod wouldn't work, but will require drilling into hardened metal and tapping new threads. Much easier to keep the stock gears.

Don't forget, keeping the 2 speed requires the use of a brake servo and you won't have reverse (unless you keep the mechanical reverse system, which is very weak and requires yet another servo).
