Randy,
I'm using an old 120FS which is a non pump engine.

I had to lower the tank just a bit to allow proper running
of the inverted engine. The relocation of the tank took about
20 min. all I did was carefully cut away the original tank
support just enough to allow the tank to be lowered as
far down as it will go. Not a big deal but poor engineering
in the design.

I don't remember if I used the supplied tank. I think I did.

As far as flight time.............10 min easy......most of the time
I was at 1/2 throttle or less.

The only problem I seem to be having is on the landings.
I put it down on the mains with no problem as the tail starts
to settle down the bouncing begins. Looks like I'll have to slow
it down a bit more and 3 point it in.
