I hate to be the one to burst your bubble - but the 130 to 140
speed could very well be your top speeds. The 180 mph is a real stretch
to achieve. I was hoping to get that at one time also while I was
building and dreaming. Now I have become very happy with 173mph true with
120 hp and a 54 x 60 prop at about 1050# in flight.
The guys with the VW's that can help you need a little more
information like empty weight, tri-gear or fixed and even the altitude of
your field could have bearing on the prop required.
As for the sensitivity be aware that you could induce
oscillations at any speed and the most dangerous speed is at take off and
landing associated with your proximity to the ground.
Welcome and hope to hear more from you
