I have gone over it with a fine tooth comb.I am nearing maiden flight but I would like to know what it is, I know it is a SIG, other then that I am clueless. I also would like to know what is the proper CG for it if anyone has any idea. If not ill put it at the spar.
All the radio gear was Kraft AM stuff and servos were all seized. It never had an engine I am using an old magnum .52 4 stroke seems like it should be perfect.
The model is an early Sig Kadet. Those first kadets were 3 channel as one post shows a picture of the kit and it says "Up to 3 channels." In the '70s it was the primary Trainer, and actually IMO far better than the Goldberg Falcon 56 for the no-buddy-cord days.
As I look at your model, it appears to have ailerons. and since I see no evidence of servos in the wing, I assume the old thing of using torque rods from the inside do the trick.
One thing that the original Kadet really needed, but SIG never made the change until some later versions, is DOWNTHRUST.
Your Kadet, especially with that BIG engine, needs a minimum of 5° downthrust. It will make the flying and trimming a whole lot easier. Using the standard .40s of the era, early '70s, the downthrust did not fit the cowls, so mostly we convinced the newbies to rid themselves of the cowl and set the downthrust in. Those that refused to do so, usually crashed quickly (no buddy cords back then) and had to rebuild.
The downthrust allows the engine to pull down when powered up, and revert to trim when at idle. You will trim some "up" when under power, then when you idle back the trim takes over and the model doesn't try to dive out of the sky. You can either play with the downthrust and get it fine tuned or just try some and go with a "Good 'Nuff" amount. But a straight thrust line will allow that flat bottom wing to make life "Interesting".
