Glad to see you're having fun, on heli's keep all the end point adjustments at 100%, I wouldn't use expo either. A better way of more precicely tamming the aileron and elevator down, is go into the swash mode and dial the percentage down, take it down to about 30% and the Blade CP becomes a very stable heli. I'm not sure on the Hitec Tx, but on futaba I just bought short Rx crystals and plugged them into the 4&1 and it worked great. They are definitely way better to fly with a programmable heli TX.
