Someone mentioned in the forum - when we discussed some related topics - that the max supported number of engines in FS is 6. I doubt about it. Isn't that 4 only? I can not see any ways to read or set parameters for 5th and 6th engines in the SDK.Gabor

4 engines is the limit, anything above is done by trickery by tying two or more engines to one of the four default ones. Of course you also need to increase the engine power to get the correct power as if it had the correct number.
