...........yep Mark you are right about a few more MPH hiding in the forward CG. With a forward CG you always have to carry a little up elevator for level flight; therefore more drag and lower speed.
Just got the email from Dan about yer visit............. I may be working on Sunday...........so hope the plans are for Saturday......
