Hi all, I just maidened my rv-4 today, with a saito 60 twin up front. It flies so scale like with that engine! I fly at 6000', so I didn't have a ton of power, but that is what makes it fun, flying it carefully enough with the available power. (APC 13x7 @ 9200)
This airplane flies the approach like a dream, it is so stable, but once it gets into ground effect, it wants to bank and yaw to the right like crazy. Tried the flaps, and even at a hefty 7 lbs, I would swear that thing flew the circut at about two mph. I covered it the same way as shown in my avitar, and it sounds so cool in the air with a twin cylinder engine! I think I may put flying wires on my tail though, after reading one of the posts above.
