I have a Seagull Edge 540 (.46 size). I am converting it to electric. I need to know how to determine what the correct motor placement is. Does anybody know of any math formula or anything that would help?

Thanks,
Kenny

Obviously the motor must be mounted with the prop in the same place as it was for IC, so as to fit the cowl. Add a bit of down and right thrust to the mount.

As Dr. Kiwi said... the motor must be in a place so that the prop is where it would have been if an i.c. motor was fitted. Also with a fully cowled installation like the edge the motor must be carefully placed so that the spinner lines up properly with the cowl.
There is no special mathematic formula that can work that one out, some trial fit ups are probably the best way to get it set properly.
