Hey, good to hear you got a new toy!!!

As per your questions....
1. The radio is most definately a futaba. The trainer cord is the new square futaba plug. Just make sure to get a single conversion crystal. Havent tried it but should work perfectly.
2. The im not sure if the lipo cutoff for 11.1 is programmed into the unit. Ill find out from our GP rep tomorrow and post then.
3. Same for the amp draw, ill find out.

GP has been very good about technical support so i will shoot an email out right now and get back to you sometime tomorrow. Happy flying.
