Hi Bob,

Mine came out a little over 20 lbs. with a Wren SS. With your Wren Gold 44 and a lighter pipe you're still looking at about 18 lbs. dry. I think it was Mark who mounted a Wren 54 in the tail, even with no ailerons his came out 19 lbs. dry.

I think their F-16 is a bit too big and heavy for 11# of thrust. Your take off weight would be about 20 lbs. I'm sure it would fly but not very well. 14# is the minimum I'd put in one of these. Their Rafale might be a better candidate for a Wren 44. Unfortunately it has a bifricated pipe which would loose some thrust.
