I didn't get much response to my last data set, but I'll try again. I'd
like to get some comparisons with other Kitfox's. Today I started max gross
weight testing:

Take off roll in 15 knots at 1500' in 92 F: ~700-800'. (No flaps.)
Take off roll in 6 knots at 1500' in 80F: ~900'. (No flaps.)

Absolute ceiling: 10,670. (density altitude)

Cruise TAS: 81mph (at) 5800 rpm (At 10,670' density altitude.)

Thanks. Tomorrow I start with rate of climb and descent testing.

About 621lb. Hmmmm, maybe I'd better check those scales, though I can't
imagine them making that much difference.

Guy,

My IV weighs about 700 lbs on amphibs and on my Grass runway solo at 950
asl at 70F it is flying in 400 feet or less with zero wind.

Your at 621 lbs in my opinion should be airbourne definately under 300
feet solo.
