How to prevent Revo input gear from stripping...?

[BrianG]

I've heard of this a few times now, even with wimpy Nitro motors. I wonder if it's a matter of raw power or speed? I've broken the shear pins, but never stripped a gear, but I'm only geared to about 35mph. I wonder if the heat buildup of high speed running is simply softening the gears until they are soft enough to break? Obviously, metal gears would help this.

I brought up a thought in another thread about the emaxx tranny. How about cutting some ventilation holes in a couple places (and on the bottom) to help cool the internals? Then, secure some screen material to keep the main debris out...
