Minor quality-of-life suggestion: the roll stability augmentation should disable itself when pitch exceeds 80/-80 (or thereabouts) degrees. If you try to do a loop with it on, as soon as you pass vertical it will violently try to fix the upside-down orientation which will result in spoiled maneuver at best and sudden unplanned disassembly at worst. It's very annoying to have to remember to do it, it's very dangerous to forget to do it, and the option is meaningless at such attitude anyway so it seems like a good change all around.

KAX has some turboprops. With AJE, the smallest of them has 680 peak HP (more like 450 in practice) and weighs 350 kg. That's close enough for small planes for me, but if it's too big you could edit it to reduce power and weight a bit and get a decent approximation of a light engine.

Yeah, it works without AJE, and to make sure it's not craft design I placed the engine directly on the battery.

I'm running the newest versions of KSP, FAR, AJE and KAX and unfortunately the electric propellers from KAX don't work. They flame out immediately with "out of fuel". I do have electric charge on the plane.

Does FAR understand propellers? I installed FAR with KAX and noticed that my planes are suffering from very poor top speeds and dive characteristics - a fairly sleek 4.5 ton design with the 120kN radial won't break 130 m/s in level flight and 150 in a 60 deg dive. FAR thinking the propeller disc is a solid surface and putting very high drag on it would explain that.
