H101 Salto wing section

Post by Peter Balcombe »

Looking at designing a new built-up wing to go on a PT ¼ scale Salto.

In common with most scale model fuselages, the Salto has wing root stubs with the original airfoil section, which is thought to be a Ritz 1 type as far as Pat can recall.
Pat thinks that the model would fly better with a Ritz 3 section.

Has anyone a better (airfoil) suggestion for this aerobatic model?

Have you checked with Cliff Evan's as he was going to do built up wings for Pat's models.

Peter. The first thing you should check is the angle of incidence of both roof stubs on the fuselage. Many years ago I picked up an unstarted kit for the PT Salto. I built it as per plan/instructions (bear in mind I had built several PT kits before) and very nice it looked too. When I flew it however it had a serious right hand turn which could only be held with full aileron trim. I checked the wings for warps but they looked true. I eventually checked the angles of incidence and found there was a 2 degree difference left to right. This was traced back to the wing stubs themselves. I eventually managed to bodge up a fix but this is the only fuselage where I had this problem.

I think I know who was getting the job ;)

From what you say Brian, it would be worth Cliff giving the new mould doner fuselage a good coat of looking at before potentially perpetuating any possible offset.
