I strengthened the inside of mine with Carbon Tow using 2 part fiberglass resin. Folded paper, laid the tow inside and pour small amount of resin, let tow saturate and place inside (important to sand and clean surface with acetone first). The other method is Bob Violet's Vpoxy which is two part/or hysol glue.
I picked up lots of ideas by following "How to build a B-1 bomber" on UTube.

Im working on installing the tail wheel mounting plate and the directions are a bit unclear. It says to have the plate 1 7/16 below the fuse at the center. Do they mean measure at the center of the opening down 1 7/16 or do they mean both ends of the plate to be 1 7/16 below the fuse at each end?

chisep51

which tail wheel are you using? Sierra or Robart?

I ended up getting it to fit correctly, this Carf Mustang project is my the next level for me so the learning curve is tough.

Hi all Mustang fans,

Finally started with the sliding canopy, the rails are done and ready to be fixed on the fuse.

The mechanic will be based on the one from Edhamp (page 53) with a servo.

Hey guys, great to see the thread is still ongoing.
Have not done much to the mustang as of late, doing house, yard stuff now that the weather is good, and flying my Corsair when the opportunity presents itself.
I did however have the great chance to get up and close with the mustang I am modelling. It flew in for the weekend so I had to take the opportunity for a few pictures as well as some discussion with the pilot. They we amazed with what my mustang looks like, and could not believe that modellers love this as much as the full scale guys.
Was a super day

Hi Guys
I thought I might put a couple of pics up on my Mustang I have been weathering the plane and burnishing the silver areas to make it look like aluminium, she is 8 flights old and the pics of her flying were taken before weathering had started.

Runs a DA 85 with scale exhaust Sierra gear and sliding canopy.

Your mustang looks real good.
I was wondering if you could post a few pics of your engine setup.

I can do that, pic one shows the muffler box mounted with high temp silicone, I had vibration issues with the box, so it now soft mounted with the silicone, doesn't look to fancy but works well
pic 2 shows air directional fins that run past the head of the engine, Because of the cockpit floor height I couldn't do it the new manuals way, this works well with a top plate in which the ignition battery sits on, good for nose weight and air flow, pic 3 show exist out for air, the muffler box gets real hot, pic 4 shows top plate with ignition battery.
I have formed a tunnel past the head of the engine so all air flow must go past the head of engine. I have also managed to get the throttle servo and choke servo along with a 32 once tank up front all in a ply box under the muffler box

Hey Craig...

It's been a long time since I looked at this thread... for some reason I wasn't getting alerts anymore. Anyways, with renewed interest into my own CARF '51 I read the whole thread end to end.

You have done a fantastic job my friend, anyone could simply print your posts and have the most comprehensive instructions around. Not to take anything away from all the other excellent builders, but thanks for sharing your experiences with this awesome model.

I can't wait to see the finished product (including video).

Cheers

Thanks Goose

That picture looks familiar Get out of my airplane.....LOL

Thanks for the pics p47p38, Looks like a nice set up.

I have not done to much lately on the Mustang. Retract plumbing is complete, as well as all the servo wiring. Lots of wire and airlines in this plane.
Next I will be working the gear doors............................[:@]hate doing those[:@]
Still have not picked up a power plant as of yet, but have all winter to get that figured out, and installled.

Like I said doesn't look to fancy with all that silicone but works well I opted for the air out under the muffler box because of the heat from the muffler
Since these photos I have dress the plane up some more including getting rid of those nasty seam line underneath The plane has had all the silver burnished and has a mild weathering to it it looks 100% better . It took some time to work out the muffler problems but now its great and the DA85 is a nice engine for this plane.
Next time it fly's I will get a full video on it for you there are short clips of my plane on you tube during its test flights. the first flight was a dead stick due to the muffler box
I run a power box royal system in the plane. When I took it to it's first scale rally, Dick Smith's rally it got in the front page of there news letter and my Ziroli Hellcat won WW2

Building my c-arf mustang for two years now, hope to be finish next summer. #1- is there anyone who have some experense whith the Kolm100 IL [link]http://www.kolmengines.com/IL100-IL130.95.0.html[/link] The weight is near 3 kg, is it to hevy?, -do I add weight in the tail? the power is 6,6Kw (9hp). #2 - The 130 IL 3,6kg ang 8,8KW (12hp)
I will for sure get one of these to power the Mustang.....

Gentlemen -

First I'd like to say I'm very impressed with the work shown in this thread - I'm a newbie here and am nowhere NEAR the skill level of you guys. But I love the P51 and would love it if you could share some of your expertise.

I just bought a used (but in great condition) Hangar 9 P51 Mustang, 80", with an Evolution GT 35 gasser. The plane is gorgeous. Currently has a 20x10 wooden BMT (not sure of the brand) prop. The previous owner said this engine has PLENTY of power for this plane - in fact, it was too fast for him (he's an older gentleman and flies mostly bipes). Have not flown the plane yet. I'd eventually love to run this plane with a scale 4-blade prop, but my understanding from reading on RCU is that 3 and 4 blade props are less efficient than 2 blade. Is that correct? Would I lose significant thrust with the four-blade setup? I'm thinking if I lose only a small amount of efficiency it might be worth it for the scale look, which I think would be fantastic.

Also, would like to know if it's possible to install real, active exhausts on this P51. Can anyone give me tips or pointers on that? Thanks.

Microdon2:
I don't know much about the evolution Gt 35 engine , but if you are looking to add scale exhaust you can go to this web site . It is called www.Keleo-creations.com . When you are on the site contact kelvin he is the owner, for your engine he may tell you that he will need some dimentions of the cowl inside to determine the space available to fit an exhaust for your engine. Most flyers would use a reduction drive to use a four blade prop to get scale speeds.I don't know how much space that you have inside the cowl so that would need to be checked out.

Are those canopy rails available for purchase from someone?

microdon2

My Feedback: (47)

Rick - found those exhaust systems on the Keleo site - thanks. Turns out he does make an exhaust for the H9 P51 150 with the Evolution GT 35, but at $250 it's a bit out of reach for me right now. Maybe later. Would be VERY cool, though, to have a working 12-port exhaust!

Canopy rails are from Dynamic Balsa for the Mustang you can get manual or pneumatic

Tobbe and others,

You still out there?

Tobbe I have communicted with you on another forum - the CARF Spitfire.

Didn't realise that you have had both. Which do you prefer and for what reasons? I am waiting for my local agent to get a Spit into stock in the next several weeks and in the interim went to see him and have a look at other CARF models that he did have including the Mustang just to get an idea of quality etc assuming that the Spit would be similar. He ( the agent) is a well known and very experienced modeller in our part of the world and wasn't particularly recommending one over the other but did make the comment that the Spit in model form flies well ( as does the Mustang) but as in the full size has ground handling issues such as a tendency to nose over on landing. The Mustang though is less prone to this due to different geometry.
I made the comment that when you go to local fly ins there are always lots of Mustangs and few Spitfires and that was one reason to go with the Spit ( less common ) . Maybe the handling issue is the reason.

He also recommended the DA 60 as the motor of choice for several resons. He stated that the CARF 1/ 4.5 war birds were originally designed for the Zenoah 62 and while a very reliable and proven motor the Zenoah is heavy and has a poor power to weight ratio. I know this is true, as I have one in another model. So apparently you don't need much more power to fly these models "scale" and the DA 60 is more than enough. Mind you he is a DA dealer. But he did also say that the DA 85 which others seem to be using is overpowered, needs a crankshaft extension to set it up ( not recommended by the manufacturer and voids warranty as it places too much strian in the shaft bearings) and because it is physically larger creates more heat, needs a bigger canister ( installation space issues) and possibly needs to have the head or plug partially exposed necessitating cutting the cowl.
These issues he felt would be more so in the Spit.

Any thoughts greatfully received.

Cheers,

Tim

I would go with the DA85 you can be sure that the power for this Mustang is correct it allow you to have that little extra on take off and it is not over powered. I had heat issues with mine but not due to the engine itself, it was heat from the muffler box running a scale exhuast. I have scaled the plane right uo and it weights in at 18kg with scale exhaust and sliding canopy full cockpit ect.

The evo 35 will turn that 20x10 well over 7000 rpm.. Kelo should be able to make you a set of scale exhaust if your willing to pay the cash.. Your performance will diminsish with 3 and 4 blade props, they just are not as efficent as a good 2 blade..

mothy1946

Thanks p47p38,

That was in fact what I was told. The heat generated from the canister of the bigger motor can be a problem. I didn't make this clear in my post. Apologies.

Cheers,

Tim

And it looks great in the flesh and sounds fantastic with the scale exhaust system!! I'm fortunate to live 2 mins from p47p38's place so got to see this puppy in the flesh during the entire build and he has done a fantastic job!!

Yes it can be a problem with the scale exhaust but i overcome it by air out at the bottom of the fuse.
If you run a pits style muffler I don't think there would be any issues at all, personally I wouldn't run a smaller engine in the mustang.
