RE: modeltech dragonlady
This airplane is very similar to the Model Tech Joss Stick. Actually, the only difference is the wing is on the bottom and they added a cowl. Having said that, the Joss Stick is close to 10 pounds. That definitely puts it outside of the the normal 60-size airplane.
I first ran a Magnum XL 1.20 2-stroke on my Joss Stick ARC. It was a perfect match for the plane but the engine was a lemon -- turned me into a deadstick king. I pulled the Magnum and install an OS BX-1 (1.08) -- marriage made in heaven.
