hey david radio is in ecexpt for the two aileron servos. Going to get it weighed again this weekend at the lhs so i should have a number for you then. The retracts work great for my first try at the i'm really pleased how they came out. And last question yes that is lk primer but a cheaper alternative to lustre cote will be good. How closly does the dupli color match the mk. Hoping i can get this pretty much wrapped up this weekend and then pick up on the nano rare again so hopefully i'll be posting over there in that thread again soon. But yeah i'm really happy with way it is turning out. Phil
