RE: Transition from Foam??
Since the detatchable wing is key, you might also try the H9 twist. Nice and small, flies very well. I'm not sure if the 40 sized MOJO has a removable wing option.....???
Standard servos work great in the Twist as does a .46 engine. There is a huge thread on this plane in the ARF forum. I had one awhile back.. Nice harriers easy torque rolls, great waterfalls. The normal flight envelope was good, too. Easy slow landings. The only thing I didn't like was how much coupling was present in knife edge. It took lots of mixing to get rid of it. you wouldn't have that problem with a Mojo, but you'd need to build it (not a problem). I just think you'd be more comfortable with a Twist banging around in your cap than a Mojo. Oh yeah, they cost like $99 bucks, too.
