What components are you putting in it?

I would not recommend putting those esky servo in your T-Rex or any of the electronics. The esky quality won't do your T-Rex any justice.

I second that...wait for better electronics.

It took some time for my Trex to get it flying (About one and a half months) and now it is just so fun that I do not regret on any component of my choice:
SA version with stock motor and ESC
Futaba 401 Gyro and digital 9650 servo.
Hitec miniservos HS65 with karbonite gear (3 of them)
Align 3c 2100 mAh Battery

With the exception of the batteries thats the exact same components I used in the Trex 450sa and Mini Titan review.

Yes and it works great!! Thanks for your previous advises and that great review that was very helpful for me.
Now I am having a great time with my Trex, I am flying it almost every afternoon and hover very acceptable, not bad for one month pilot. I have to say that I am following your sim training program and it is so great. I have the G2 sim and I will wait till the release of the G4 to upgrade.
