Hi,
New here and at the final stages of purchasing my first RV-6A.
I have a question related to take-off performance:
When I test flew the aircraft, and had my buddy do another testflight we both experienced almost the same take-off performance which we both felt was not super impressive.
The RV-6A in question is powered by an O-320, 160 HP and a 70CM6S9-0-77 prop.
On the day of the test flights - We had the following conditions:
2-3 kts headwind.
12 degrees Celcius.
1017 hPA or 30,05 In of Mercury.
Approx Half Fuel.
Two POB of around 170 kg (374 lbs)
Airport is at around 2000 feet MSL, and Pressure altitude was 1888 ft - Density altitude 1958 ft.
Flaps were used ( I guess around 10 degrees).
Take off took 21-23 seconds from wheels stop to lift off on both flights. Rotation was done at 70kts/80 mph.
During the ground roll the engine never exceeded 2200 rpm ?!?!?
To me it seems really slow, and I am wondering if this is right ??
I kind of felt that the owner was overly nursing the Lycoming (my experience tells me that they can take a lot), but should I be worried ?
Any thoughts ?
