Kadet Seniors have huge wing area and can handle many different engines. I had an ARF with an OS 46 LA. It flew slow-n-easy. I was able to quickly solo as landings and take offs were sooooo easy to manage. The same ARF with an OS 61 FX became spirited. So spirited that it exceeded the wing's ability to stay in one piece. That one I chalked up to "pilot error" because I did not manage the throttle.

So? If you retain a decent amount of "throttle awareness" from your teen experiences the engine size won't matter. If you push the throttle to the wall and leave it - smaller might be more survivable.

Above all - have fun.

Btw - used to work at Main and Goodyear. Where do you fly? And, does your id have anything to do with the AU Zips?
