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 w= ant
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!!

Gonzalo

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?
Dave
