Hi RcTerry,
First, let me congratulate you on being very wise and logical in your approach to flying. Taking a step back to learn the basics is something that most people are not willing to do. I'm not surprised that the AeroAce has been useful to you, but I am surprised that the Estes has also been useable. I've tried to fly a couple of Estes planes and found them to be very frustrating. As soon as you get the hang of it, it cuts out on its timer. Definitely put the SuperCub back in the air, but first read the Six Rules For Success by AEAJR. Its a MUST READ for beginer flyers.

For your second plane, the overwhelming favorite is the T-28 Trojan from ParkZone. Buy the PNP version and use your own receiver and battery. Even though its a low wing plane, it flies better than the trditional high wing aileron trainers like the Multipplex Minimag and the GWS E-starter. Do a search on this plane and you will be amazed at the positive responses.
