I have one on my G62, pointed forward for so the prop blast acts like a ram effect. The main reason I did this was to keep the fuel from being spit back out of the carb. Tends to make a mess on the plane. My G62 (C&H Ignition) spins a Zinger 22X10 @ 7200 rpm. Hovers my Giant Stinger around 1/2 throttle.
