I just got back into the hobby and started flying again a few months ago, I had moved to an area where the AMA field was literally a mile from my house. It was too much to drive by it and not get out there on the field. I was rusty on my my flying skills since it had been since the 90's the last time I flew. I had just finished an Ultra Sport 60 I converted to electric w/retracts but was scared to fly it because it had been so long. Hesitant to take that chance, about a year ago I picked up a Trainer 40 Carl Goldberg Eagle 2 with a Super Tiger 45 on it. I had to do a little minor patch work and rebuild the engine, but all is well and I've been flying it. I'm about a half gallon away on the Eagle 2 before I try the UltraSport 60 out.

I'd go after finishing that Sig Kadet you have, if you have the plans you should be able to complete it. The building skills is just as important as flying, that way you can easily fix minor dust ups like a hard landing etc. The flying characterics of the Kadet should be on par with other Trainer 40 in the same class like my Eagle 2. Once you master the Kadet getting into faster semitrical wing planes like an Ultra Stik or 3D's should be as easy transition. If you want to 'build' 35% scale stuff tackle that Kadet first. Patience, little at a time, is all you need with building.. It took me quite a while to finish the UltraSport.
