I didn't think to put a motor glider in my list, but if I did it would be the RF3. (Same as the 4, but with a wood spar, smaller engine and no aerobatics). I owned a RF3 for two years and it's a delight. It looks cute, but like many motor gliders is a compromise and the harmonisation isn't great. It needs more bite in the rudder. Also, mine didn't have a decompressor, so if you switched the engine off, that was it. I once landed out and had to hand swing and take off again. It didn't soar very well!
I thought about helicopters, but none look right and none fly right!
