RE: GP Old Timer 40?
Ed,
If you're thinking of the big gull-winged Stinson, then Reliant is correct. The Old Timer's wing does remind me of the Reilant but the fuselage has more of a Taylorcraft look to it. And there is a resemblance to the Rascal as well.
I learned to fly RC with a 3-channel Falcon 56 and you're right - it is a simpler way to fly. But I'm probably gonna need ailerons on my Old Timer since I intend to put her on floats.
