My MVVS 26 IFS weighs 38 oz with ignition and the measured thrust with a Mezjlik 18X6 CF prop is 18 lbs. (with a pipe you can get well over 20lbs) It burns about half the fuel per min. that my Saito 180 does so I only run a 12 oz tank instead of the 24 needed on my 180 saving roughly 3/4 lb in fuel weight. I have mine in a Sig Mayhem at the moment and I am more than pleased with the performance. It hovers at less than 1/2 throttle and punch out is great. I confess that I haven't tried it in anything like the plane mentioned but I thought the numbers I had might help out some. Good luck with whatever you go with.
