Engine Mounting Compatibility Question

Are a GMS .47 and a Thunder Tiger Pro .46 interchangeable on the same motor mount without modifying it?

GMS 47 and OS 46 FX are interchangeable , I don't have a TT so can't speak for that swap

And I have a OS 46 and a TT 46. The mounting holes line up, but for some reason the TT's mounting holes are a wee bit smaller. You might need some new mounting bolts.

Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:

Also, the Tower Hobbies 46 is made by GMS for them. It is the same engine as the GMS 47, except for different carbs and a few other minor items.
