yea the batterie charging idea worked thanks, im going to buy new batteries and new charger soon, both are old and garbage.
But one more thing happened:
i recently bought a traxxs titan 550, it was very cheap thats the only reason i bought it (like 5 bucks, dont ask how i got it that cheap, its complicated), but yea i put it in, had to modify the back a little to fit the engine, but i dont know if ill get the same speed or more, if the same, how i can i beef up the engine?? new speed control?
