Hello Redbear,

I have a Great Planes 60 size Cub with the 90" wing powered by a Saito 91. I also have Goldberg Anniversary Cub, also with the full wing powered by a Saito 80.

Couple of things come to mind. Firstly, have a good think about how you are going to transport the Cub. The ideal vehicle is like a Chev Tahoe or Suburban but I can stuff my GP into my Honda Accord but with only one occupant...me!

Secondly, do justice to which ever Cub you buy and install a four stroke engine. They look and sound so real compared to a bee in a can two stroke.

My GP Cub was a very nice build for the most part. The tail feather balsa was like heavy lumber but apart from that I am happy with it.

The Goldberg Anniversary Cub has pathetic die crunched parts which fit even worse. Inspite of that, the plane flies very nice..I test flew it today with floats, see picture.

If I was to build another Cub I think I would really like to buy the brand new Sig laser cut 1/5th scale. From what I understand it is a first class kit, very scale like, even with a functioning door! I would think that your OS 91 would be too much power and that a 70 four stroke would be the ticket but thats just my thoughts.

Good luck choosing, take your time and build it true and you will love the yellow Cub

Cheers

Mike
