yea that's for sure.
I don't know the weight offhand but I run a corally RDX chassis powered by a 6000mah maxamps pack for practice and 5000smc pack for the club races here. no weights on it, but I do have the receiver on the batt side, and I'm lookin to put the tekin FXR esc on the batt side as well. I'm also thinking of getting one of the low profile lightweight hitec servos aswell to fine-tune it's balance.
it's like the lotus elise of the RC world.
Offroad on the other hand, is a whole other animal.
