Telemaster here is you picture. Does the Fuselage jig look familiar? A friend in the UK over on the RCMF forum in UK sent it to me as a gift! The Fi pieces on the front of each side are positioned wrong and the previous builder forgot to predrill the holes for the blind nuts. He installed them at a right angle to the side but they should be tilted forward so the are at a 90 degree angle from the center line. I will need to cut them free and reposition them and laminate another piece of balsa to the front of them or replace the stringer which will be too short when they are in the correct angle.
