Well I finally flew the Giant Twin Sportster yesterday after a couple of mods.
When I first tried it, I found the nose wheel assy was just not strong enough for the model. New assy fitted, engines run in and off to the field.
She flew straight off the drawing board,only a couple of minor mod's (more down thrust, less control throw).
It is not overpowered with the .91's, will climb about 30 deg. angle. It was flown hot until I start doing some engine out training and see what its VMCA is like.
Setting up the radio so that I can have independant engine control and train single engine (get the fingers working).
Now think about the big DC3......!
