They work fine on a Rusty. I run 48p, mod.8, and mod 1.0 on my Rusty depending on what motor I am using.

The Warnings & Cautions discussed in this manual cant cover all possible conditions/situations. It must be understood that common sense and caution are factors which cant be built into this product.
if you examine the gears closely, you will see that the mod 0.8 gear will "crash" into the next tooth on the other gear prematurely, hence causing excess ware and will eventually destroy the weakest gear.

the porthole from the noob world an here has been opened!! that's how i got in.
I can testify to the fact that you will not wear out the gears quickly. I ran RCM 32p pinion against .8Mod plastic spur for over a year at least 20+ hours and never had a problem. If you do have a problem it would be the plastic spur gears that cost ~$3.50, but like I said I had many hours of use without a problem
