I'm trying to decide on what engine to put in a Astro Hog Biplane. I'm leaning toward a Saito 100, but I like the slimline look of the RCV90-SP engines. I don't know of anybody using an RCV and don't know how well they run. I'm not even sure if the RCV will work, as they appear to require a larger than normal prop size. Does anybody have any experience with the RCV?
Thanks

I have two but have only run the .90. They run very well and are not fussy, you're right about the large prop, I'm running a Zinger 17x10 four blade on mine at just over 5,000 rpm.
