Hi Alan and other posters
I have the Rotax 912ul with a 70" warp drive prop. My cruise by gps is 100mph at 5100-5200rpms and 4 gallons per hour fuel burn. Empty weight is 650 lbs. I am surprised that the corvair powered HD only has a 90mph cruise. Maybe it is the prop setting. The gentleman who posted yesterday (sorry I forgot your name) was absolutely right on with his comment on wing loading and turbulence. These are light planes with light wing loadings. Most of the turbulence I experience is due to living and flying in the mountains and it's usually windy. Almost always a crosswind takeoff and landing. On nice days I have flown as long as 20 min. without touching the stick. On not so nice days it can be like riding a bucking bronco.
For those talking about baking from the heat, I put Limo tint film from wal-mart on the inside top of the canopy and use a scrap piece to block the sun wherever needed. I think I only paid about $6.00 for the film. It works great. It is often in the 80-90 degree range here in the summer. I have the naca side vents in the fuselage and I also have a forward opening canopy of my design that I can keep open during taxi. I have flown in C-172s that were more uncomfortable in the summer.
Regards to all
John

.ExternalClass DIV {;} Hi John,
I have an HDS with about 350 HRS. and a 3300 Jabiru engine. I friend of mine has an HD with a Corvair. He said to me a couple of times that he wishes his would climb like mine does. The thing is that he is not comparing apples to apples. I have 120 HP-- he has 100 HP. My empty weight is 705#'s--his is 780+#'s. I think you are right about the ride in rough air. My HDS rides a little smoother, but if is turbulent you still get bounced around . At gross weight of 1200#'s my Vy is 1100 FPM and Vx is 925 FPM. If I am alone it will climb about 1200 FPM or a little more. There is also a speed difference. I will cruise at 125 MPH (at) 2800 RPM and he cruises at around 90 MPH. We flew from Oshkosh to Open Hangar Days at Zenith. It took him an extra 1 1/2 HRS. He said he might be looking for a set of HDS wings if someone would like to trade. I don't know what he would see for cruise speed and climb rate with the shorter wings, but it would be interesting to see. He still has to remember he has more weight and less HP. I think HP is the big thing with my plane. I fly into some very short grass fields.
I feel the same way about my plane as you do about yours--It is a solid airplane and fun to fly.
Happy flying,
AL from Oshkosh
