Well, actually is not that bad. There are a couple of runways 3000 ft long, and others 2000 ft. Altitudes varies from sea level up to 7500 ft, but I don't plan to go there often, and if I do, the runway is very long. I want to have a little more power just in case. I think the 200 HP is enough, right? Also, what about the parts, it seems that the two rotor parts are much more available than for the 20B... Thanks!!

While I am in favor of the rotary, it is worth saying that none of the very few currently flying turbo rotaries have had trouble free installations. I know of John Slade and Dave Leonard, and both have had more than one turbo failure in the process of finding what works. I do not know if Mistral is currently selling its turbo version. What sort of runway length and density altitude are we talking about, where you intend to operate?

Giménez Celis *Sent:* Saturday, August 22, 2009 3:05 PM *To:* Rotary motors in aircraft *Subject:* [FlyRotary] Three or two? Hi group. As I told in previous questions, I’m building a Cozy MK IV, and I like the Rotary idea. I would like to have between 200 and 250 HP, since in Chile we don’t have such long runways like in the U.S. and is a pretty mountainous country. Regarding this, which way is better, a three or two rotor engine? Is the three rotor too heavy? Can I use a turbo in a two rotor engine without affecting reliability and weight? Etc… Thanks.
