RE: What to buy ???
It you can handle a Extra, then you can handle the 580. JMHO Scale is a little more hard to fly and not as fun for me. I have a Scale Hanger 9 Fokker, I've flown a semi- scale P-51, J-3 Cubs and none of them are as fun to fly. When I fly my Extra I can't stop from having a smile on my face. I have a ball!
I'll always fly scale... but when I want to tear up the sky and fly hard... I get my Extra 260.
