Great planes Stuka Engine Mounting?

Hers how I mounted the OS Max .91 4 stroke pumper engine in mine!

I mounted the engine inverted for increased scale effect.
To do this you will need an OS Max exhaust manifold for your
engine I ordered OS Max part #72109500 for the FS70/FS-91
for $24.99 this allows you to move the outlet towards the rear
and then I used the stock muffler tube screwed into the 90
degree manifold to angle the muffler down. It's a little tricky
to tighten up as you must do it with the cowl unfastened to
avoid cracking it and to allow more room for the 14mm wrench.
I hope these picture help[8D]
