I just got a traxxas 4tec and i need a new heat sink because the treads that you scew the glow plug into got striped, i think its a .15 engine, its not the original traxxas one, im new the the game. I tryedto search for the brand of the engine but cant find any thing, it looks like it says IC ENGINE? the head is a 4 bolt so can i get any heat sink with a 4 bolt pattern? also i was offerd a new .18 wasp team orion engine, are thay any good? I WANT TO GO CRAZY FAST.
