i think in the future(very far future) upgrades to an ntc3 will include the XR3 radio you mentioned, a better engine(depends on class i want to run, i think. i hear the sirio .12 CRV or something like that is really good), a failsafe most definitely, and maybe a few other goodies. i think i have decided on the ntc3. thanks for all the help guys! and also, are there any videos online that i can find of the ntc3 in action?
