Hi all
Just my 2 cents, they all fly as good as the builder is at building and they all fly as good as the pilot holding the radio. I have them ranging from 40 size to 1/3 scale size, with flaps and without flaps. My 40 is a Great planes clipped, which the wood was very crappie. Hangar 9 arf from my wife on my B Day, A Sig 1.4 scale clipped excellent plane and sweet flying, 2 1/3 scale balsa USA, 1 Super Cub and 1 J-3 Cub and another 1/3 which was built from plans. And a 1964 PIPER Cub COUPE. I am a CUB HEAD, I have not seen or flown a bad one yet. getting back to your answer. 1st choice is Balsa USA ( scale detail ) #2 is Sig #3 is G.B. and # 4 is G.P. Like I said, just my 2 cents.
