Phase I Performance & Test Results

After finishing my 40 hour Phase I testing I have finally boiled down and gathered all my numbers together. FWIW I thought I would publish them here.

My airplane is a Kitfox Super Sport equipped as follows: taildragger, Alaskan Bushwheel 8" tailwheel, 21"x 8.0 x 6" Aero-Classic Tundra main tires (no pants), standard wing (no Laker leading edge), Horner wingtips, speedster tail and horizontal, factory plastic wing strut fairings, 3-piece smooth cowl, Rotax 912uls engine, 3-blade Whirlwind GA prop (blades pitched more for cruise than climb), Dynon Skyview avionics.

Test Results:
Power off stall-clean 48mph
-1/2 flaps 45mph
-full flaps 42-43mph
Power on stall-clean 43-44mph
-1/2 flaps 40mph
Vx - 1/2 flaps 55-60mph (use 60mph for safety)
Vy - clean 65mph
1/2 flaps 66mph
Stability-Longitudinal-static Positive
-dynamic Positive
-Lateral Directional Positive
-Spiral Slight Positive to the right
Neutral to the left
Maximum Vne Speed-Tested to 140mph in shallow dive w/ no flutter or control problems
Cruise Speed at 5000 rpm- 100mph TAS
5500 rpm- 109mph TAS
5800 rpm- 116mph TAS
Maximum Gross Weight Tests at 1320 lbs and 16.0" CG: as reported on previous thread.

This is all extremely close to the factory predictions so I am well satisfied. Now all that remains is putting it all into a little POH handbook.

I am thru trying to be a Chuck Yeager and can get back to being an ordinary pilot with still much to learn and lots of fun.

Jim,
That sounds great! I may have missed it in an earlier post, but what did your empty weight come in at?

Empty weight was 835 lbs with listed equipment including 3 gallons fuel (1 gal. in header tank and 1 gal. unusable fuel in each wing tank).

thanks for posting all the info Jim, and for all your previous posts that I have found really useful. Congratulations and I hope you really enjoy just flying it now!
