Hi Buggs,

I haven't flown it yet... probably will fly it within a week..

I have an FX .91 2-stroke in it not the FS.91 4 stroke. I chose the 2 stroke so I wouldn't have to cut the cowl, It was a very nice fit.

As far as flying the Monocoupe with the FS-91, it should fly well. I used a FS-91 in my TF Bonanza weighing about 15 lbs and it flew well... very scale-like.

Bill
