i think u can find some wider but not from helimax, look for parts for t-rex450xl, is one of the first t-rex and is a good setup, the axe 400 is almost a trex 450xl clone, i have found that a lot of the parts are interchangable, i have alot of old trex parts and they all look the same the frame has very little differance as they cant make the same have to make little diff. but most of the parts will work,and look into new gyro, im on my third hm4000 they last up to bout 10 flights and start acting up ive got a 401 on the way. but over all this is a good bird for the money, esp. with the futba 6ex
