Avi:

As with Nitros, electronics are critical----Servos have to be snappy with good centering. Not necessarily Digital, but they can't 'drag'. For the Trex, I'm using HS 65's, and the 9650 Digital for the tail. Best Gyro is the 401, but expensive.

Antenna is more critical than Nitro's because of the ESC & Motor & other sources of interference. I use a base loaded Deans which is tiny & neat, very inexpensive & gets rid of excessive dangling Ant wires. Agree the ant set up you described is terrible.

As for RPM, if you have a Tach, fine. However, Set up your curves and look for a good hover around mid throttle with about 6 deg Pitch. As with Nitro's, you'll 'see' & feel it when it's right for you.
