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!!

Gonzalo

While I am in favor of the rotary, it is worth saying that none of the=20
very few currently flying turbo rotaries have had trouble free=20
installations.

I know of John Slade and Dave Leonard, and both have had more than one=20
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,=20
where you intend to operate?
