I understand, you are right....

I was thinking I want to use a couple of engines I can use in other planes, just in case, I have a spare .46FX, do you think it is all right if I install 2 x .46FX on it????? what do you think about it????

I was thinking about that because I am also interested in the Mitchell of nitro planes (2 engines) and it requires 2 x 46-52 engines, do you think that I can use 2 x .46FX for both planes?????
