Received my GT3C this week flashed to 0.6.1 firmware by Losikid. Binding was exactly like the 3B unit. this transmitter is light, almost knocked off on to concrete, MY advise is to lay on it's side vs standing it up.
Only ran my HPI Flux XS so far, but very easy to use, light weight & comfortable. As to durability we'll have to see. So far on 2 hours of use I would have to give it 9 Out Of 10.
