RE: Extending Wing - Sig Ryan STA 60 Size
The wing is already about 6 feet long. It flys great just like it is. Extending the wing will make it look funny. I highly recommend a servo out in the wing for each aileron and beefing up the landing gear mounting. I fly mine with a HB 60 and it works fine. It flies easy as is but that tall narrow landing gear can be tricky. I have nosed mine over more than once on take of and landing.
