you know if you spend 400 bucks for a rtr you could get a OFNA/Hong Nor X3 sabre from Nitrohouse for under 300 bucks right now. then you just get a good 21 such as os21 xb blue head or the os21xrb blue head and an os 2090 pipe and a good radio to go with it! With an rtr you dont allways get top notch stuff and you spend more than grand trying to upgrade it when you could just build a kit up from the ground and have a blast building it! this way you get to choose what things to add such as servos and batteries etc and thats my two cents Michael
