A friend has a 1/3 Sopwith Triplane & he has actually hinged the right hand longerons so he can swing the tail parrallel with the wings for transport. Yes, the servos are in the rear section with enough slack in the leads for hinging. The split is really hard to see because it follows the split in the top decking and then follows the roundel on the side of the fuselage. The pic is the side with the split. We could not spot it until we were shown how it splits & we were looking at the model on a table! - John.
