I have more fun with the planes with a Kolibri (either it be a foamie, an EDF, or a hotliner) than with the big jets. The build, complexity, and most of all the maintenance and care you have to spend on a "big one" is also fun but rather exhausting compared to the "foamies".
Don't be fooled by the number of posts here on RCU about this sudden interest for nano turbines : it is not in proportion whatsoever to the number of pilots actually having one or will be having one.
Most people will eventually still opt for the most common turbine size.

Only negative point I am facing with, with the small turbines : we fly on grass fields and take-off with those tiny wheels is far from evident. Apart from that : I can see that I make double as many flights with the small jets than doing with a big one during an afternoon.
