I followed the links in one of the posts to see if this guage is still available, and appearantly it is not in production and hasn't been for a while. It looks like a copy of the Prather guage, and again, Jim Lee has a nice replacement prop block that is wider and more stable than the original. I just got my copy of the latest Aeromodeler magazine, and inside there is mention of a guage available from England from a company called Pylon Line and it's a copy of the Prather unit. Cost is 55 pounds, I'm guessing about 110 dollars US plus shipping.
What other pitch guages are available in the US currently? I'm checking around for a friend of mine, so he quits asking to borrow my Prather guage!
Thanks a lot,
