Interesting to read how things have come on a bit. It is years and years ago since i last set spanner on Aircraft. and in my day they had starter generators which were electric, not particularly difficult to replace, but bloody heavy, especially on the HS125 tail mounted engine, incidentally it was the series one HS125, and it even had a carbon pile regulated Inverter stuck up the tail hatch, even more fun to replace. Those were the days, the move in technology, not to mention reliability has come on leaps and bounds. The stuff i was involved with is a bit like a Telly with valves in compared to todays all singing and dancing stuff.
If you want basic, then Chipmunk it has to be, not much more complex than a glider, just a bit noisier, but good times were had back then, and we actually used to get a good few hours in them as well.
