I have returned a vintage Kwik Fli Mk III pattern airplane to flying condition.

This is the Graupner version of the airplane - it was very nicely recovered in the original Phil Kraft color scheme by it's prior owner.
The airplane is fitted with an OS 46 AX engine; Mac's muffler; Master Airscrew 11 x 6 propeller; Tru Turn spinner; Hitec Servos; Futaba S3008SB receiver and Futaba 10J transmitter.

After completing break in procedures on the new OS motor today I test flew the airplane.

The first flight was with the engine running very rich to continue breaking it in - just a few laps and figure 8's around the field for trimming. The airplane required minimal aileron trimming and some down elevator.
Trimming and test flying were made more difficult due to 10-15 mph direct cross winds from the north.
Upon landing it was noted that if the airplane carries a little too much speed that it will float and likely require a go-around.
Subsequent flights featured further engine tuning closer to full power. Aileron throw was increased slightly to improve roll rate, rudder and elevator throws were set up properly and did not require changes.
The airplane has excellent vertical and level flight speed - the engine / muffler / propeller combo is correct for this airplane.
Basic aerobatic rolls / loops and stall turns were made in flights 2-5.
The airplane does not spin well (hardly at all) with it's current settings - attempts to experiment with more radical aileron throws

The Saito 80 Engine needs bearings, it was in my Top Flite Contender. I put about 30 flights on it before it started to emit a "super charger" type whine. It ran great but I removed it and swapped in another Saito 80 - I was afraid the engine could sustain damage if I continued to run it with the failing / worn bearings.

The carburetor is new in the package. See the photo for the part number.
