RE: Official T-rex 450 XL SE Thread
My only experience with T-rex carbon frames came with the assembly of my SE and putting the servos in first as they needed to be mounted from the inside(hs-56's) would have made it a bit easier.
Boostcrzy, you are right on the digital gyro, I run a Gy401 w/E-flite S75 now in another T-rex. Although it is not digital, it does real well especially at the proper headspeed. I can only imagine digital with a 9650!!
