I had to use the metal side frames on the longranger and a small modification on the aileron servo. You eithe have to trim the top part of the fuse and slide the helicopter back some or you can line the main shaft like I did in the middle of the helicopter and just have to move the aileron servo back like 5mm not alot. it is a great fuse to work with as far as painting and sanding. take care mike lansford
