I recomend mounting the evivator sero's on the top side of the servo trey, Not the bottom. This will give more clearance from the pipe. we used 8611 Servo's

Going with a carbon spar might save you a little weight but its no necessary to. If you use a carbon spar you shouldent have any radio problems from it.

I have been using the 2.4 system in my jets since the Spektrum DX7 came out. I have had 0 problems with it. We use the Spektrum 2.4 setup in all of our demo jets here at Skymaster-USA and we have never had any problems with the systems. We are using the new AR9000 receivers and the Smartfly EQ6 system.

I hope this helps...
