With the upgrade, you should expect these performance gains.
Our Piper test aircraft have shown the following improvements:
Increase in climb performance +200 fpm. After takeoff, we typically see 1000fpm climb for the Bold Warrior and 800 fpm for the Cherokee Scout.
Decrease in takeoff roll: -350 ft
Increase in cruise speed: +6 kts (6-10 knots depending on propeller choice.)
Increase in service ceiling: +3000 ft
Range at 75% POWER at 8000 ft: Range increase of 35 miles
Of course nothing is free. To achieve these numbers, expect an additional fuel burn of 1.2 gph on average. There is a 18 lb decrease in useful load as the empty weight increases due to the slightly heavier motor and propeller.
Our Citabria 7GCBC test aircraft have shown the following improvements:
Increase in climb performance +800 fpm.
Decrease in takeoff roll: -550 ft
Increase in cruise speed: +16 kts
Expect an additional fuel burn of 1.2 gph on average. There is a 18 lb decrease in useful load as the empty weight increases due to the slightly heavier motor and propeller.
Glider towing is currently be tested. More info to come!
