A very heavy engine for a model 3 too much wt up front.

I know someone with a Model 3, that I think has that engine. Let me check.

avoid the tempation. I had one in my model IV and it is to heavey. Put the 912s in and double performance. That was my experience.
I have a Kitfox 3 with E81 built by Jack Bally featured in EAA 1993 mag. Great aircraft.

PS 100 pounds heavy than a 582 ???? what the 582 weight....62 pounds
That just about makes your III a single place doesn't it? My III with 912 is just barely a 2 place for slightly larger folks.

what do you weight 300 # ?aircraft @ 672# pilot @ 160# passenger @ 140 # can carry up to 26 gal of fuel but why fuel burn around 3.5 gph so to reach max weight add 13 gallons of gas (78#) or 3.7 hrs of flight... total weight 1050#... plane works great for me ...it is what it is ....personal plane to fit my needs cheap to fly...maintenance... park in my garage..and fun to fly

Glad you joined in. You gave the weight, but perhaps you could provide some performance numbers too. I think some of the concerns about weight are if the kit had 950 gross on the data plate instead of 1050. I think it is the Kitfox II that is 950 though. As a point if contrast, my Avid is empty weight 560 including the BRS; also with a gross of 1050. I fly with my son fairly often, and together we weigh about 425. Nice you and your passenger are light enough to make it work for you. My son and I should lose about 50 pounds between us.

I hear the EA-81 is popular with the Avid crowd, and they seem to like it's power/climb well enough, so would it not work on a Kitfox-3 or 4 just as well?
I think I saw a typcial install weight of about 205 lbs on a previous post, kinda on high side alright, but you might get up to 85HP out of it (at the prop).
