anyone know of a good biplane arf for a os 55ax saw the seagull biplane but have never had luck with seagull models to cheaply built.

My Seagull Ultimate 46 is the toughest plane I own. It has been cartwheeled down the runway and pancaked in several times....and never any damage, other than bending the landing gear....which easily was bent back in shape. It has come through without a scratch, when most others would be in pieces. Don't overlook the Seagull Ultimate. You may be pleasantly surprised.

The SIG Mini Smith is also one tought plane. I must say that KITS end up being ten times as tough as ARFs. When you build a kit you add glue, CA etc. The ARF companies seem to "SPOT" glue. True, my KIt builds are a "little" heaverier but they "...take a licking and keep on ticking" !
