REFLECTOR: Performance Question

[Scott Derrick]

Dave,

I started flying a shortwing RG / 200 HP / Performance Prop.   I've lost 
the  numbers for the PP and I just looked at the prop(hanging from my 
ceiling) and they are not on it.  I have a Catto now.

That Performance prop beat Catto's prop in take off distance and cruise 
speed.  I hated giving it up, but thats a different story.  My best 
guess is I lost 5 knots off the top end and use about 15% more runway 
with the Catto. Craig said we could close that gap with some prop tuning 
but I haven't tried it.

As Ronnie said you should do your initial flight testing from the 
longest runway that is available. Can't be too long.

I fly into 4000 ft runways with no problem as long as I'm near sea level 
and not gross.  You should have no problem.

My problem is that I do a lot of cross country flying and rarely leave 
with less than 45-50 gallons on board.  My standard fuel level for 
departure is as full as I can get the tanks cause I'm not panning on 
stopping for 600-800 nautical miles.  This puts me in the position that 
with two people, lots of  lugauge and my assorted bags of tools and 
flying gear I'm within a 100 lbs of gross.  4000 ft near sea level on a 
warm to hot day near gross weight will raise the hairs on the back of 
your neck as you see the end of the runway fast approaching  as you are 
raising the canard at Vr.
