Hey guys. I figured out the cheapest way to fix the stripping gear problem. Strengthening the gear! After 2 months of weekend racing and many crashes, the gear held up. This is not a Tamiya Legal part, but seems to hold up VERY well! I gave Penguin RC the Specs and made it the same day! The Disc is notched inside to match the gear's mold.
He will probably go in production on this part very soon I think it will go for about the $6-$10 range. I am not sure..it is really up to him.
