.21 maxx, or 2.5maxx?
get a monster pirate. its 169 without a motor and you shouldnt get the hyper engine because its a high rpm power engine and it doesnt have much torque, in fact it wont even go up a slight incline in the grass without a push. I put a thunder tiger .21 in mine and it has much better torque, and i now just figured out ts slightly faster than my friends with the hyper 8 port. plus the pullstart is weak and breaks very easy on the hyper. this is a good truck if you like picking shock fluid and setting up suspension when you build it, but if you just want a toy get the max. it is less work to get it running
