I am planning on building a Warbird pylon racer with a YS 1.10. If you know, what is the best prop for speed for this engine?

Thanks, Terry

Whatcha building?

The YS- 1.10 is a beast--- I am not sure about the 14x12, my YS-140L turns a 15x12...

APC 13X13N for break-in. Use care not to over rev in a full power dive with this prop!
For a World Models 46 size P-51 ship use a APC 14X14 and cut off 1/4" each tip (13.5"dia.) reshape and balance. 30% Powermaster heli fuel.
USE ONLY YS AFTER RUN OIL !


Drip in some thin CA on the inside of the fire wall and wing hanger areas. Remove covering at the wing center section and where the fuse rides on the wing and fiber glass it.
Stiffen up the horizontal stab too (carbon fiber).

AND HAVE FUN! YAHoooo!

Thanks Guys,

My plan right now is to mount it in a Phoenix Strega like the one in my avatar. I will pick up the props you've suggested and give them all a try.


I will be reinforcing it as suggested.

I hope you don't rip it apart with that BIG motor. I don't think it has retracts, so it will be dirty so I would drop back to a APC 14X12.

You're right, it doesn't have retracts. As far as dirty goes, although the landing gear is there, it also has a much thinner wing and fuse than the World Models P51. The one in my avatar has a Sport Jett 50 in it and it really scoots along. It is also much lighter since it doesn't have the extra weight of the retract gear. I believe I will still be ahead with this model. Since I am going to beef up the wing I may take a look and see how difficult it would be to do retracts while I have it open but I will probably stick with the KISS method.

Really? Good ol' wood? I wouldn't have thought of that.

By the way, I found a thread about beefing up a Strega to handle the YS 1.10. You can see it at http://www(dot)*********(dot)com/forums/showthread.php?t=14277
You will have to replace the (dot) with .

A lot of good info in that thread.

....lumber, baby !!!....I use the 14-8 on the .91 YSFZ. It wouldn't quite pull the 14-10,
but the 1.10 will.

A friend said he is using a 13x10 APC and getting almost 11,000 RPM. Is that too high for this engine?

Thanks, Terry

....it is fine. The engine is rated even higher than that.

Thanks Dave,

I've got another question. The engine I bought doesn't have a header or muffler so I will need to buy one. I have heard that a lot of guys run these on a straight pipe. I'd like some recommendations as to what is going to give me the best performance. Links to good products for this would be greatly appreciated.

.....I would probably just get a stock muffler for it. I don't think those super pipes
are worth the money.

I use a 13x13 four blade. It might seem like alot, but it is covered up by a huge 3.5" nose cone.

APC 11x14. Go for the highest pitch x rpm you can get it.

I've run an APC 13x10 on my YS 1.10 too and got 10,700 - 10,800 rpm on 20/20 fuel. The engine sounds happy at this rpm level. I'm running an APC 13x11 right now, which works well too. It's installed in a slowish airframe (105 -115 mph tops).

For a cleaner airframe, the APC 13 x 13 Narrow could work well.

Terry, I run a YS 1.20 header/collar on my 1.10 and no muffler. It's a stainless pipe with a flare at the exhaust port end. The collar tightens up against the flare to hold it in the port.

It's effectively a straight pipe about 2.5 - 3" long. Tower has discontinued the product so I can't link to it there or on any other site. Sorry.
