one thing I've found that needs to be done that isn't clearly pointed out anywhere is that after you've set everything up like you want it, go back and rebind. (on JetCat's this requires readjusting the ATV on throttle and then relearning the RC in the ECU). I've seen where allot of people skip that and when they first turn on their jet some surfaces jump to odd positions till the TX and RX link up, this is because they didn't do a rebinding after they set everything up (dual surfaces/mixing/etc...). make sure your gear switch is also in the down position when rebinding..........
