Not having flown my IVP (piston) yet, I found Brents comment that 3520 is "not comfortable" to be very useful.

However, 3200 would not even get me 100 gals and 2 occupants.

Could someone please comment on how it flies at 3300 and 3400?

Also, what is the nature of the "not comfortable"? Was it unstable in pitch mainly?

thanks,

Colyn Case
