REFLECTOR: Speeds

[Ron VelocityXLFG]

All good info I must have been a sleep at the wheel  I seem to have  only 
see the plane flies at 200 + kts.
Now with the light shinning on the more true air speed I feel much better. I 
thought I had a real slow plane
as it turns out it is not so slow. I just had  just High expectations and a 
Fixed pitch prop.  As Time moves one
I will build a Top end prop to see what that is like.

Scott,

At 7,500 feet I can get mid 150's kts KTAS 52F burning 7.5gph. Just watching 
the EGTs and setting them, not using a lean assist program.

I am running dual EI. (E-Mag & P-Mag)
