Actually, I just set the engine and prop config that I would use in reality. So if I would have got myself the Showtime 4D (which is not possible as the same is discontinued), I would put in a FS91SII and 15x5 or 15x6 and that is what I used in the sim. Even in the Showtime 50 I plan to use the same config because the 55AX/72A would be too underpowered for 3D and 81A is too expensive + I already have a FS91SII waiting for that airplane.

In case I get the Reactor Bipe, it would still be the same engine config: FS91SII with 15x4 or 15x6 prop.

That way I would get the most realistic simulation and the airplane would fly closest to reality

I fact I purchased the engine with the consideration that I would be taking one of these two airplanes
