Instead of Cessna mucking around with the Skycatcher, I wish they'd restarted the C152 line. Improve it by widening the cabin a few inches and the seats to go back further. Add a bit more useful load eg use a climb prop to maintain cert. climb gradients. If it's 5 kts slower it doesn't matter.
I like a six pack instrument arrangement for training. Ditto manual trim to a trim tab - the feel for how much trim is needed to relieve the load is important, and the rate of trimming is controlled by the user, unlike electric trim.
