Kitfox IV Speedster Performance

Greetings all. Just joined the forum and new to the Kitfox community. Have an opportunity to purchase an unstarted Kitfox IV Speedster kit at a hard to refuse price. Before I pull the trigger I’m looking to see what the actual performance specs for it would be for such plane with a 912 engine.

Does anyone have those on hand? I called the Kitfox office and they said they didn’t have anything available to provide as far as a spec sheet but could answer any questions I might have. Thanks for the help.

David.

I just happened to have the original literature handy

Perfect. Thank you all for the input.

Were there any design changes between the Denny Kitfox IV-1200 and the Classic IV from SkyStar? My research leads me to think there isn’t but would love to hear the input from the owners and builders. Thanks.

Dave

My Classic 4 from SkyStar had the nose gear and tail wheel mounts and also the larger elevator.
