I inherited this Sig 1/6 Cub many about 20 years ago and stuffed it in rafters of garage. I recently returned to rc flying and I am in the process of restoring this plane. I don't have any plans, door and cowl are missing. Assembly wasn't great, but I have reglued and re-inforced many parts. I have a 2nd generation OS FS .60 that I would like to mount inverted but it appears to be way too big for this plane. Its the only small 4-stroke that I have. I guess I could mount a .40-.46 2-stroke if necessary.
As I mentioned, I don't have any plans and I am wondering what the tail, wing, and engine mount incidence angles should be. Looks like the top of fuse where wing fits is not level so I may have to re-work that area. And, the tail assembly looks like it was barely mounted above the main fuse stringers which looks odd to me. And, the landing gear fairings are hard-mounted to fuselage which doesn't look right since the spackling would crack or has cracked in a hard landing.
Any help would be much appreciated.
Stab and engine incidences are zero, the wing is minus 2 deg.
The landing gear were hard mounted to the fuselage and yes they do tend to crack the finish after less than perfect landings.
The stab is mounted on the top of the truss longerons, the two top stringers are mounted over it and tapered to blend into it. This plane was designed to fly on an .25 to .30 size 2 stroke engine, a OS 40 LA works well on it. A 60 four stroke is way to much power and weight for the airframe in my opinion. This is the 1/6 that SIG still produces today I have built three versions of it over the years, and as others have said it flies the wing not the engine, don't overpower it.
