I built it and it has a warped vertical fin. I tried to email the people ([email protected]) in Australia but the address is NOT VALID!! Who do I email now??? I want a new kit because even the ailerons are warped!! Anyone else find the tank a tad high causing the carby to drip like a guy who had too many beers without going to the toilet? I don't know if I should even take this bird off the ground yet unless these people who built it can rectify the problems.[:@]
