Just finished building the Nitro Tiger Moth. After thinking a bit and studing the Pacific Aeromodel Tiger Moth instructions, it became clear how it went togher. Required no mods or parts. I did deside to mod the wing wires, however. I used small springs at one end to keep tight, works well. I am using an RCV 120 for power. Will fly soon.
Also, the CG location is now illustrated on the Nitro Web site.
