Hi I have some wooden props labeled "TF" " pylon racing"
I'm not a pylon racer but these props seem a bit big for true pylon racing

they are a 9 x 9 , 2 at 9.5 x 8 and a 9.5 x 8.5

are these safe for higher rpm sport engines.. I can't find anything about their rpm limits and would like to know more about them before I try them out

thanks

I have some of those props, They are made from Top Flite. I wouldn't go past 24k with those old props.

Hi!
They are 30 -40 years old!
No one uses these in pylonracing today.
They are even a little bit large for the average sport .40 engine today...but could ofcourse be used for sportflying.

well this is interesting Ive found out their very old props firstly.. secondly I now have a 10k spread on performance

the thing is.. I dont think any of my engines will turn one of these at 24k, but I will easily turn one at 14k ..but I think i might even get 17k+ out one of my engines.... maybe I'll have to experiment..at distance

Who knows next you might even get the pylon racing bug like the rest of us have
