Hi all,
I have done around 25 hrs in my (purchased) RV3a (G-RODZ formerly N68AR).
It has around 480hrs total time on it and as far as I can see from logs, it has had the same engine/prop combination throughout - Lyc 0-320 E2A and Culver wood 68/68.
I find the prop too fine, as it red lines the rpm with a handful of throttle left to go, and only achieves around 140 knots flat out. It does climb very well though.
My question is, as this engine/prop combination has suited the previous owners, is this the best set up as a compromise between speed and climb?
For me, I would prefer to utilise all the RPM range, sacrifice a little climb performance, and get a better top speed.
My 8 will be flying soon and I then want to refurbish the 3 and use that opportunity to improve performance. Can anyone suggest a new prop for my existing engine, or a better engine/prop combination?
Thanks, and Happy New Year!
David
