I do see coyotes point..and I take the critique to heart...will study up. Its one of those things where I knew the answer, just didn't connect the dots. Just didn't think it would have that much effect....
As for RPM control...well...I have over 900hrs in Schweizers...so RPM control is actually a piece of cake. Although you wouldn't think so from my question!! Probably asked it the wrong way!!!
oh well.
And by the way....I take offense to being called a Robbie pilot.
Just stuck in one for now!!
