yeah im tryin to replace the one plastic gear. its a sacraficial gear so it goes before anything else. but ive already broken one and had to change things in the front of my truck that i dont like. i have run a hitec 5955 with my set up with no issues.. and a airtronic 358 with metal gear conversion on it. im wondering if somthing like the metal gear for the airtronics would work in the 1015 is what im tryin to figure out. the rc8t i hear is hard on servos anyway, because we cank the servo saver down hard.. then i also run a long servo horn wich gives it a decent amount more throw on the wheels
