I found some calm air and the GPS said I was doing 130mph. Normally I can tell by the rpm but had 10-15mph wind and guest up to 30mph so the rpm didn't do much good.
Ross R/Gang:
Correct me if I am wrong. I was under the impression there wasn't much correlation between airspeed/engine rpm and ground speed. Ground speed is determined by airspeed, wind direction and speed, and direction of flight.
However, to get 130 mph ground speed in a MKIII, you'd have to have a 35 mph tail wind. 95 mph WOT straight and level airspeed in a MKIII is about max, no matter what engine you have pushing it.
Maybe you can share your secret for 130 mph cruise with the rest of us slow poke MKIII flyers?

Maybe he put VG's on the prop
I would have guessed tailwind also, but flying with that much wind would just scare me. That does bring up a question though, what is the maximum wind you have ever landed in John ? I have seen you comment on high winds while flying cross country, what is the maximum wind speed you would launch in for flying over flat terrain ?
