Hello all!
As some of you know I recently finished building and have flown new to me RV10. So far everything looks good but there is one moment which I am little bit unsure about.
On takeoff roll when I set throttle full forward and while rolling my RPMs are 2550-2580. As soon as I take off and climb to 100-200ft RPMs gradually rise up to 2700 and stay there while limited by governor.
My engine is a standard IO-540 and my prop is Hartzell two blade model (standard one recommended by VANs).
Since I am getting RPMs at a right number (2700) and they stay there during climb I assume my governor does its job correctly limiting max RPMs. However why don't I have full 2700 when throttle is full forward on the roll ?
Governor which I have is old Woodward (155 model I think). It is set for 2700 and it works well in the air for all RPMs range (55% to 75% settings).
Governor test during runup goes well, RPMs drop when knob backwards is noticeable at 1900RPM or higher.
Do you think it may be a problem ? How your RV10 demonstrates RPMs at t/o roll ?
I used to fly Cherokee 235 with similar O-540 engine. Gross weight there was 2900lb and takeoff RPMs 2550 max for that engine. I assume since I am able to reach that it is already safe for takeoff but....
