RE: cubs make good trainers??
Its your money, but I would not recommend it. Cubs have some funky flying characteristics that requires some experience before tackling. There are some conditions where you need to cross control them, and they will spin. They do not self-recover like a trainer does, and (as mentioned above) they are usually only good for one crash.
I know what you mean about the stigma of high wing trainers, but ya gotta learn how to fly first, and that high wing trainer is your ticket to success. The Duraplane is a poor excuse for an airplane IMO. If you want something different, look at a 4Star 40, or even a something extra (with the contols tamed down and a small engine). The Midwest Starduster is even better, if you can find one.
The smaller scale cubs don't really fly like cubs anyways, so in a way you will be short changing your self...Once you get into 1/4 or 1/3 scale they start coming into their own and rewarding the pilot with something approaching the full size cub. Things like a 600 foot take off riding on the main gear with an ever so gentle lift off and a shallow climb on runway heading....done at less than 1/3 throttle!!! Flying with the engine ticking over so slowly you can hear the putt putt of every power stroke (good with 4 strokes..) Landing, and floating for a surprising distance til one wheel gently touches the grass, followed quickly by the other, with the tail still flying until the cub is almost stopped...... ya can't beat it!!!
Keep the dream, but learn to fly first!
