Great news. I know the cowling on your plane looks, well, just H-O-T! Good luck with the next install!

Both ailerons are made the same up to the point of the drain hole 'installation'. I found a lot of interesting construction 'constraints' in the Grummans that reduced the manufacturing parts count. A lot of parts are interchangeable and some with minor mods. The rudder and elevator are interchangeable on the -1s and that part is modified with the trim tab for the other elevator. The vertical fin and the horizontal stabs are interchangeable. The wing is designed to use two sheets of 4'X8' aluminum for skins so no custom aluminum sheet is needed. There may be more 'similarities' that I've missed. Linn Ian Matterface wrote: > I asked the question "why two aileron trim tabs" of the AYA back in > 94.
