A guy at our field got frustrated flying various modern ARFs too soon after he soloed. Things like a Tower Uproar, H9 Twist, etc. Even his trainer was high powered. I suggested he was trying for too much performance too soon. He bought a Goldberg Eaglet 50 on Craig's List and put an OS .15 LA on it. It flies beautifully and he has been enjoying it for a year now. It is about the same size and weight as the Kadet Jr. and has only three channels.
Several years ago I picked up a Kadet Jr. with an OS 25 FP and had a great time flying it till it crashed when landing on a gusty day and the oil soaking caused major joints to let go. I'd still like one. They are as big as most electric trainers and the engines run great. I have the plans. If Sig still sells the landing gear that would be nice. Looks like an easy scratch build, and you could easily make it lighter.
