Status: offline 		I have just finished putting together a World Models T-34 and I know these things are raced with 46FX's on the front.

What I want to know is what prop are these guys using on their 46FX to get the speed out of this plane?

What sort of speeds are they getting?

I won't be joining the racing anytime soon, but I do want to practice some speed flying with it.

Also I wasn't really sure where to post this question, so if there is a better forum please let me know.

My recommendation would be to prop with APC Narrow pylon prop 9x7.5 or 9.5x7 (depending on weight of your plane). This should be just right for the OS .46 and give you plenty of speed for what it is, with draggy airplane. Also, make sure the engine turn in the high 14,000 to low 15,000 RPM range (more would be better) to get the maximum performance. Hope this help.

Happy flying!

Sam S.

Yes, thank you! Somebody else has also recommended I use an APC 9.5x7. So it sounds like a consensus!

We are using the Apc 9.5 X 7 but also using bolly 10>5 X 7 and are doing real well. It all depends on the style of flying. The bigger prop is faster in the straits and slower in the turns. The little prop is slower in the straits and faster in the turns. We have a race, the finals in Morgan Hlll on October 5-6 . Call me to register is interested. We register frequencies and race numbers so no conflists happen. My email is [email]konorred@aol.com[/email] or call me (408) 626-9851. Have a great time.

Yes, I already have this in my calendar.....I am taking the T-34 out this weekend for the first time, so depending on how this goes I may come down.

What is the format for the weekend?

Can you race one day only or do you have to race both days?

Do I need to bring a spotter?

Status: online 		For a sport plane the T-34 is not exactly a draggy airplane. It went pretty fast with a TT 46 and an APC .46. Wasn't racing it but other members were impressed with its speed. The Super Sport 40 is as fast as the T-34. Seems to be the same wing. One of our members was flying it with a 11-5 prop, I convinced him it would go real good with a 10-6. It did but he prefered the thrust of the 11-5.

Sport_Pilot,

No pun intended by saying a "draggy airplane".
Was just comparing to what I'm use to see and flys... Quarter Midget http://www.pylonworld.com/rc_pylon/qm-40/qm-40.htm and Quickie http://www.pylonworld.com/rc_pylon/q-500/q-500.htm.

Status: offline 		I flew it for the first time yesterday! I ended up using a MAS 11x6 just to get the feel of the plane and next time out I will try changing the prop. I was very happy with it and it did have a reasonable turn of speed. Anybody have a rough idea on actually how fast these things really go? I was running Powermaster 15% with a MAS 11x6.

Great flying planes arent they. I have three of them set up for racing. Actually one for racing, one for practice and one for a spare.
Using Power Master 15% fuel, a 9.5X7 APC prop, OS#8 plug, baffel removed from the muffler etc we have clocked these at slighly over 90 MPH with a CHP radar gun. Typically we set the engine up to hit 14.8 to 15K on the ground and go. At 15K or more rpm you start running a good chance of leaning out in the air, the last thing you want to happen during a race.

Yes, indeed they are! I was very happy with the way mine flew.

Sounds good! I now have exactly the same setup except for the fuel where I am using Powermaster YS 20/20.

Sounds like your ready to go. Just go fast and turn left :-]. You will have a ball.

I ran it again today with the new APC 9.5x7 pylon prop and running on Powermaster YS 20/20.

Was getting 15,200rpm on the ground and it ran great. I really like flying this plane.....now to finish setting up my Weston Magnum and get some real speed!
