I don't know what the "protocol" is for those kind of flying sessions is, but I have experienced that taxiing around in circles thing with G2. Seems no matter what I did, from recalibrating the transmitter several times to everything else I could think of.. nothing would fix it. Seems I had a "loose" USB port connection. So, everytime I have this problem now, I check my USB port and problem solved. Maybe this will help out some other unsuspecting soul, who, like me, always seems to be working when the customer service helpline personnel are on duty at REALFLIGHT.
