My Bipe Special is over 5 years old with hundreds of flights. I found it very easy to put together looks great and it flys extremely well plus it is a very very strong model eg I tried cart wheeling it down a grass strip on landing once, not a problem just brushed off the dirt and grass and flew again ...
I have flown mine with an O.S. 91 FS and a Y.S.91 the Y.S. is much better if you really want to throw it about a bit. The bonus is it also fits into my car in one piece with both wings still attached

Although not really an ARF in the true sense of the word eg finished and just needing gear install. There still was a reasonable amount of building and the models duroflex fuz needed painting and the wings and tail need finishing. I glassed mine then painted with auto spray cans, Although you could go with film covering if preferred....

It is a nice change from the all the Pitts Specials and this model is a semi scale version of the EAA Bipe.

Highly recommended, I would buy another one tomorrow.....

Cheers
