I have made up my mind about the plane i would like to get but im am un decided about the motor. The plane is a WM p-51, for the motor i was thinking a Super Tigre 65 with a macs tuned pipe OR a 4 stroke motor of what size i dont know. If you guys could let me know a 4 stroke motor that would run bronze class good and maybe even silver that would be awesome. Thanks for all the help you have been giving me.

I think the motor of choice in the warbird racing is the YS 110

That would be for Gold. And he would have to make some significant airframe mods to handle it.

I run a YS 63 FZ in a TWM Dago Red 46 that is the same size. Same wing, stab, fin. Just a fiberglass fuselage that is the same size. It would barely be a Silver class plane. But it is fun and it sounds really cool without the muffler. I run an APC 11x7 and get about 120 mph with it.

I am running a Phoenix Models P-51 Strega with a TT PRO .61 and an Ultra Thrust Pipe.  It is competitive in Silver on 10% fuel.  I ran it in Bronze with the stock muffler and you have to slow down your times or you will break out.  The Strega is banned in SAMS Warbird racing but the motor should be competitive in the airframe you have decided on.  The ST .65 I know nothing about but the guys running Bronze at Kingman last month were doing just fine with a TT PRO .46 and stock  muffler in the Strega.  The ST .65 with the stock muffler and on 10% might break out of bronze if you fly a half way decent course so that means if you go wide or high on a few turns you still might be competitive.  Anyway that is where I would start.  Remember don't cut any pylons, don't jump the start, and finish all you heats and you could place at the end of the day.

I'd go with a stock 46-65 2 stroke without a pipe, or a 91 4 stroke on low nitro. Anything more than that and you're going to break out. Personally, I think I'd just get the 46AX and be done with it. The four strokes take some getting used to and are more expensive up front and to repair. The pipe is just something else to break or give you trouble.

A stock 46 AX in a WM T-34 will run just under 100mph. The same engine in a P-51 with retracts should pick up a few mph. That should be plenty fast for a Bronze racer. I'd worry more about getting the plane setup for racing and less about the top speed. Get out to the field and practice until you can't stand it anymore.

Since it's your first racer you'll be lucky to go through an entire season without crashing. Don't put any more money or effort into it than the bare minimum. Don't get attached to any plane you plan on racing.

I'm not trying to put you down in any way. I've been learning the hard way myself. I raced boats for 10+ years and barely had any accidents let alone lost one. I flew for 4 years before I decided to try out racing. Over the last year I've totaled 3 WM T-34s. Luckily the airframe was the only loss on all three crashes. The first one I almost totally recovered and did a bunch of beefing up on. The second, I only added a little color to and only beefed up a couple areas. The last two that I built I added a little color and that was it. Like I said, I'm learning.

Hey Spence,

Welcome to the world of Warbird racing. I think the WM P-51 with a Super Tigre 65 and stock pipe would be a very good combination for Bronze. The truth is, you could probably get by running a pipe on it if you don't fly too aggressively with it. The planes I use for Bronze can easily break out in Bronze and I just use good time management and they work well. Funny, when I first started, I had to fly hard to keep up with the same planes. The most important thing is to get a plane together so you can start practicing. Flying a smooth course is going to make more difference than what engine you are running.

Blessings, Terry

Another option that dawned on me last night is the 55AX.

Talk to your mentor and/or look at what everyone else is flying.

Spence-

YS 63 for Bronze and you will be just fine. If you are looking to step up to silver at a later date than a YS 110 would give you the room to grow. A majority of the silver pilots are running WM P-51's with YS110's and doing just fine without major modifications. Course management and prop/fuel can control the motorto keep you above break out times. If you need design help on the airframe let me know and I can show you the suggested modifications to be madefor either of theabove enginechoices. If you are looking to keep costs downI've got a couple of used 110fz's in my shop. I'm local andif you would like to see one run before buying I couldmakeyou a deal on one of the two.

Another thought would be to look at the WMDagoRed or Voodoo. The fuse is a little bigger and would bea hair slower, but still perform finein either class. Our next race is August 2nd, try to come out thenor make it by the field for ourOUTLAWrace 3rd Sunday of every month at noon and introduce yourself.

Sorry i havnt been here to respond but i just got back from a trip. thanks for the help. Money is somewhat tight being hat im a 16 yr old workin at a grocery store. But im thinking of going with WM P-51 with either a os 46 AX or a TT Po 46. i looked at the price of a ys 4 stroke and **** a gold brick. i just need something to get a taste of racing to see if i even like (which i probably will) but thanks again for all your guy's help.

Whats the difference between Thunder Tiger and Super Tiger is there much noticeable difference or what. Cause they both seem pretty solid from what i hear.

Do yourself a favor and save the coin for an O.S. if you are going to use a two stroke engine.
Especially if you plan to race it, You need for the engine to be reliable. It's not always the fastest that wins. More often, the most consistent.

In my 34 years of playing in this hobby, Ihave never had an OS that wouldn't run like a watch.
Ihave seen other folks using other brands that caused them more trouble than Iwill accept from an engine.
The amount of enjoyment you get from your hobby is in this case directly linked to the quality of the equipment that you use.
So, how much finicky engine type problems are you willing to tolerate when you just payed 35 bucks to enter a race?

I would buy the Thunder Tiger Pro series.  A lot of bang for the buck and just as reliable IMNSHO as the OS and save a few jingles that you can spend on something else.

Mauraderer,

Do you know what the all up weight is of your Strega with the TT .61?  Just curious.  I am in the middle of putting an airframe together for the Silver class and am just trying to get some information about various set-ups.

Thanks,

T.</p>

The Thunder Tiger 46 Pro gets my vote.

5 lb 14 oz with the stock muffler. Check out this thread snd other at <a href="http://www.*********.com/forums/showthread.php?t=20685">this site.

There are other threads for WarBird racing at that site.  But, it is for the RCPRO rules not your SAMS rules

Yeah, I am talking about the RCPro races, I was in Kingman and got the bug... 

Thanks for the reply, that is very helpful.  Did you have to do alot of mods or add much weight to get it to balance?

T.

Not really.  Did you check out that thread I sent in the last post?

It won't connect so I pasted the URL.

It wont let me do that so I am PMing you the url

Can't see it, it is one of those that RCU has blocked and it just comes up with stars, (*****).  If it is from the RCPro site, I have read many of the threads about the warbird racing, as well as those on RC Hangout and the plethera of other RC sites.  I am just trying to get some information from others about what they are doing so I can find a decent starting point for myself.  I have a Strega that I am going to run in the Bronze, but am up in the air about what to do for the Silver.  I have had numerous conversations with Carry and a few others so hopefully it will all come together soon.

What he said ^

talk to dave today and he gave me some tips but one thing i would like to know is what size prop should i run on a st .61

12x6 or 11x7 to start.
