Hello everyone. I have owned an RV4 for the past 2 years & absolutely adore it. It was built in 1990 by another owner & I have a performance question to ask.
It is a fairly "vanilla flavour" basic aircraft with an O-320-E2A 150Hp engine. Propeller is an "Ian Henry" 2 blade wooden prop. It climbs at 1500 to 1600fpm & cruises at 140 knots/ 2500rpm. Does that sound about right?
According to the Vans website, I should be closer to 165 Knots. I seem to be down quite a bit in speed which I assume would be attributable to the propeller.
I was hoping to contact someone with a similarly equipped 4 that I could compare with. My aircraft is a little porky at about 1015 lbs empty but the figures seem quite a bit out.
Thanks guys.
