Cool video Mike! She flew pretty good on one engine at the end, which one shut off first?

Inboard quit first. This flight was after a repair. On the 2nd flight of this model the outboard nacelle with part of the wing and engine and tank attached broke! Engine wide open with a full tank! That part took off under power and went about 150ft and crashed in some trees. The rest of the airplane flew quite nicely with one engine and half a wing til it ran out of gas. No one injured thankfully. I beefed up the nacelles with some 1/4' basswood and haven't had any trouble with it since. I should have done that to begin with but i just followed the plans.

How about a photo of the plane? All we see is a blur. Mind you, a very good performing blur! Sounds great too.  What engines and props?  ::)

Yes, I'm interested in the engines, too.

I put a couple of mismatched Black Widow mutts on my XF5F Skyrocket.  The outboard ran longer but it didn't hurt anything.  Mindful of the engine's desire to go their own ways, I provided quite a bit of extra beef during assembly.

The wood plank was an alignment fixture to get the engines going the same way.  I couldn't find a finished picture.
