Netheads, For what it is worth, I have come across a site about props, one comment there was that the ideal prop speed is, a tip speed of 680 Ft/sec. This may help in the selection of the correct prop. Robin New Zealand r.macdon...@clear.net.nz

Unless I'm mistaken, and I've known to be, but as I remember from college the speed of sound was 1127 fps or something along the lines of 723 mph at mean sea level with the speeds of course decreasing as you progress to lower temperatures. The speed of sound was roughly four times that at the densi

Netheads, I guessed it would open a can of worms. The site I looked at gave an ideal speed of 680 ft/sec, & it looks as though you should never exceed 900 ft/sec. So this should give anyone a rough guide of what the RPM should be for a given diameter. If the RPM is out you should change the

You have too much prop when the engine cannot make the rated rpm static, or perform to the specifications in flight for cruise/top end. You have too little prop when you cannot make the lowest advertised cruise speed or top speed with the engine running at or very near the redline. You can also

Hi, the size of a prop is given as 2 numbers diameter/pitch. In terms of maximum speed, the pitch is the important number a one inch pitch would give 2.84 mph, so a 49in pitch prop would give a max speed of 139 mph at 3000 revs and 64in pitch gives 181 mph at 3000 revs. VWs are normally limited t
