Am starting to build a Lou Andrews Aeromaster Too kit that has the option to construct the wings in three configurations. I am considering the swept option for both wings. Does this present any stability problems? Also, noticed kit only shows ailerons on bottom wing. Should this be changed to ailerons on both wings?

I would definitely put ailerons on BOTH wings!

I have 2 aeromasters that were built by a excelent builder (Chuck Gill from The Aeroplane Works) When he passed away his son gave them to me to keep and restore.

Chuck has probably owned 5 or more aeromaster (his favorite plane) and the two I have only have ailerons on the bottom.

this says that the kit most likely flies fine with only the two. if you are feeling up to it maybe you can build 2 top wings and try it with only bottom then try it with both.

hopefully I will have these flying before next spring.

as for wing configuration I dont know which one these have but I can get photos off all 5 (2 planes and one spare wing) of the wings for you.

let me know.

Master modeler in our club has built a couple 60 size bipes which are scratch designs evolved from his Andrews Aeromaster of some years back. These planes fly like in my dreams. Both have straight lower wing, backswept top wing, fwiw.

I'm finishing up and GP Super Aeromaster 60 which is identical to the AAMCO Aeromaster Too (I have that kit also) except for the cowling, wing attachment, and rear wheel attachment. I went with version 3 (both wings 52-1/2" swept). The ailerons are 19 inches by 2-1/4 inches and two (2) provide all the differential the plane needs. Watch the CG it is different for each version. I had a version 3 Aeromaster (AAMCO) bumper kit from 1982 to about 1993 or 4 with painted silk. It flew quite well but covering got tore and rear end was terribly soaked with exhaust. This one is covered with Ultracote and powered by a ST 61 ring. My trouble areas were throttle linkage, and one aileron wasn't flat. I would also recommend not using rubber bands for wing attachment per the AAMCO kit. That is the one positive improvement of the GP over the AAMCO. Also, don't ignore the 1 deg neg incidence on the upper wing. It helps. Stay in touch and be real careful about the mods you make to this plane.
