My friend,
Max is looking for an additional propeller for his world-traveling rotary
powered aircraft.
Max
currently has a 70” dia x 60” pitch wooden (reverse rotation of course) on
his Tracy 2.17:1 gearbox. This limits his engine rpm to around 4900-5000
for take off and he seldom sees above 5200-5300 in WOT flight. He believes
that perhaps a similar prop with less diameter may be the answer to improving
performance. My original prop was a 68” x 72” and I could easily get
5200-5300 on take off and around 5600-5700 at WOT, but that was for a different
airframe than Max has.
So if any one
has a prop occupying space that they want to sell and that fits
somewhere between 70x60 and 68 x 72 and fits the hub of Tracy’s RWS 2.17:1 hub,
let me know the specifications, price and condition and I will be glad to pass
it on to Max.
Best
Regards
Ed
