whats the heaviest motor ever put on a Kitfox

[David47]

Not sure if it’s the heaviest but I’m putting in a Lyc 0-233 which weighs 210lb dry together with a Airmaster CSP which weighs 24lb. I can still take 2 people and full fuel but have to reduce baggage which is no big deal.

While I would hate to be the winner in this fat engine contest, my Continental IO-240(125HP) weighs in at a portly 250ish lbs with accessories. At least this is what I thought when I installed it years ago. At OSH this year while wandering around I saw specs for the IO-240 that had it weighing 277 lbs, yikes!. Having said that , I have to say my Series 5 performs great and here in the east haven't found any airstrips I can't get in and out of. Prop is a 11 lb wood sensenich. We cruise at 120 mph true , takeoff dist -350' solo, and land 350' if i try hard. Bruce N199CL

I was holding back too. I believe the dry weight of the IO-240 is listed at 246#. Just like Bruce I am very happy with the performance of the aircraft with the IO-240 on my model 5 Kitfox. I think I ended up with one of the lightest planes with the IO-240. I have a useful load around 660# and over 500# with full fuel. My normal flying CG is always near the front limit (me and fuel), but I can almost put the full 150# of cargo in the back and not be out the aft CG limit.

My IO-340 with accessories and harness etc weighed in at 279.5.

Blowing the dust off this thread. New guy question: Do all of you folks with the heavier engines have the 1 degree forward sweep as well?

[ken nougaret]

Mine does not have forward sweep with O-200A. The manual said to do it but John Mcbean said not to. He was correct and balance is perfect.

[ridgerunner]

My 7 has 1 degree as well

[PapuaPilot]

Mine does.

That would be an affirmative to the wing sweep on my IO-240 powered Series 5. Bruce N199CL
