TM100 engine of Baykar has two large alternators that provide electric power to the electrical systems on board. This takes power away from the propulsion leaving 100 hp to the propulsion. However a civilian system will not need as much power for the electrical systems. So a derivative engine from this engine can use smaller alternators and have a bigger power left for propulsion. I am guessing such a derivative engine can have as much as 110 hp to 115 hp propulsion power, looking at the large size of the alternators. This kind of power can be used to power both 2 seater and 4 seater airplanes. Rotax has 141 hp and the new 160 engines for 4 seaters but 115 hp is reportedly also used for 4 seaters.
