More questions about feathering

[jordonj]

I have noticed somthing about feathering the Lancair Legacy.  When I try to feather the props the plane slows down, is that supposed to happen.

Also, I can't seem to go very fast at high altitudes...

Is this just the Legacy or is that just how planes work?

When you feather your prop, if I'm not mistaken, you disconnect your prop from the engine, and when your up high, make sure you got your mixtures set right, and yes, you can't go as fast, cuz theres just less air for the prop to bite from

Doesn't feathering mean you change the angle of the prop blades?
If so, of course you'll lose speed when you feather, since the pitch angle in your case  probably is changed to a lesser efficient one.

But then again, I'm really no prop-nut  :)

Believe that 'feathering' is pitching the leading edge of the prop straight forward, usually in the case of engine failure, so that it cuts thru the air rather than inducing drag that a normal pitch, unpowered prop would produce..

But of course, I could be wrong.. ..and according to the wife, usually am.  :P

Makes sense...

I'm flying cross country using a Lancair Legacy (cause there's no way I can afford a real one).  :(

Anyway I just flew from Las Vegas to Monterey, CA.  I was at 18000 feet and I had to keep the throttle and feathering all the way in to maintain airspeed and altitude after finding the trim sweet spot (the LL is a tricky plane to trim).  The fastest I was able to go was about 160-107 KIAS.
