Who has been the highest in their Kitfox?

[Esser]

I was just perusing the Kitfox site and once again I saw the claim of 160mph cruise at 16,000ft with the 914

What's the highest you guys have actually been and what was your TAS?

[Av8r3400]

I was indicating 130 at 11.5 once. My GPS showed 170 ground speed, but that was the huge tailwind. I never figured the "true" airspeed. Honestly I was freezing my @$&!s off wearing shorts and a t-shirt at the time. But the tailwind was too big to pass up!

Been to 12.5 myself, everything seems to slow down a bit at those altitudes, kind of nice.

[Slyfox]

I think once I made it over 1000 ft.

A few years ago I got my Model IV up to 14.5, and still had 200-300 fpm climb. I don't remember the airspeed, but I was solo, less than half tank of gas, the engine was 100 SMOH, and it was a cool spring morning.

That's how I usually fly too! I used to joke that I was going to red line the altimeter at 500ft...

I had mine to right at 12000. I had posted a photo of the Advanced Flight System showing 11500, but I can't find the photo.

way to go, welcome to the club. I only go up to 1000 cus my airport is in a congested area.

Haven't been over 10,000 but had to do a rate of climb test for the test program.


for interest, here are the results - I wouldn't claim my timing and my holding exactly to 65kts to be all that accurate, but it gives you the general idea!

cheers

I'v been to 8000 feet with 52 horse power.

Ross, I suspect the altitude in your table are from the altimiter and not corrected for density altitude? Here's your climb points on the graph I made during phase one flight testing. Classic 4 at 760 pounds gross weight and 52 horse power Rotax 503.
