i just droped my 7700 in my tt-01. this car flys!! i need some help with my driveshaft. i dunno why but the front of my driveshaft seems to be loose. i have already changed out the chassis. no gears look striped, all screws are tight. another thing i noticed is that the smallest curb check will effect the tt-01 even with alloy parts. I'm at 700 bucks and counting, i just started this hobby and i haven't even got into planes yet.
