RE: Too Fly or not To Fly?
Troy,
The T-Rex doesn't have any electronics except the motor and ESC. The last time I crashed my 450 I think it cost around $40 and most of that was the canopy, but it held up pretty good. It really flies good, but I don't know how it compares to a B400 since I don't have one. I also use the DX7 with mine.
