Howdy,

    I seriously thinking of building a Cozy Mark IV, and of course
powered by a rotory. The plans are for a 200 kt plane with a Lycoming
O-360 180 hp engine. Is it feasible to push this plane 250 - 300 kts
reliably with a rotory?

    Any comments would be appreciated.

Thanks,
Lurker Richard

Richard,
I agree with Paul, Chris and mainly Al Gietzen. When CO-Z Development says
180-200, obviously they are reffering in MPH, not in Kt.
Increasing the power, the plane will have a increase in the climb rate. To
increase the max. velocity, will be necessary lots of power, making the project
insane.
I am seriously thinking of powering my Cozy with a rotary, between 235-250 HP,
and I will be very happy if I reach a cruise velocity of 190-200 Kt, and a climb
rate about 1500 fpm.
But remember, extending the VNE or power without structural/ aerodynamics upgrades
maybe something dangerous.
If you want to try to expand the possibiliies of Cozy project, go ahead. And
please, be carefull with that act.
