No doubt that the Kadet is a very popular trainer, thousands of guys have learned to fly them and some long time R/C pilots like to keep them around for just a fun to fly airplane. Hydro is correct that Sig build instructions are quite good, the kit quality is OK. Some of them also have a plastic engine cowling that you would need to paint. The rub on that is spray cans that will withstand exposure to fuel are pretty much nonexistent these days. You really can't go wrong with a Kadet however let me throw some food for thought at you.

I personally like a trainer with a bit more capability. The Kadet series all have a flat bottomed wing that limits it's flight performance. Not really a big deal as nobody just getting started needs a trainer that is capable of some aerobatics. However what that flat bottomed wing does is give the airplane lots of positive stability. Sounds great right? What this means is that if you get into a shallow dive the airplane will pick up speed and self recover. That also sounds great right? However nothing is for free, this also means that everytime the airplane has a change of airspeed it will either climb or dive slightly. Some guys do prefer this type of setup as most full scale airplanes " trim " in the same manner. With a trainer with a symmetrical wing ( same curvature top and bottom ) you can initially set it up to have this same positive stability by placing the center of gravity slightly forward then as you progress you can move the center of gravity back a little to expand the airplanes capabilities and use the same airplane to learn some basic aerobatics.
