I just got off the phone with horizon and I ordered the regular evo 46 prop hub instead of the weighted one. It was only $2.99 so I am now going to stick with the motor it comes with. No reason to change now.



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/12/2005 9:25:04 PM)

Mike,
Yep, except they use that aluminum clamp type mount jeez I hate those[:@]. I took measurements off opposite sides of the firewall to make sure that the prop drive was lined up at the correct distance from the firewall. The hardest part was getting the cowl off. Now it slides on nice and easy as the OS cylinder and head is smaller. I am very pleased with the install, just gotta see how it flies without the cowl at first and will probably make some thrust adjustments. I bought a 2 1/4 Dubro spinner 11 X 6 and 11 X 7 props today to start out with. I tach my engines, so after this puppy is broken in I'll prop from there off the tach readings.

tychoc,
Are you referring to this trainer version of the Evo, or the other model that sells for more money? I'm not going to start an engine war, but have never had an OS let me down and I find them quite reliable, user friendly and easier to adjust. The FX feels lighter than the Evo as well. You like the Evo, so enjoy it, I'll make you an awesome deal on this new one complete with the muffler, spinner and prop if you would like another[:D].

balanced mine and adjusted the throws on mine this morning and off to the field[:D].got there and fueled her up it didn't take much.and decided to run it for a time check.after 5min. it died.hmmmm removed radio and fuel tank and found the pressure line turned down and only letting the tank fill to about 1/4 of capacity.fixed that problem and fired her up.this eng is the smoothest starting and idleing i've seen.idle and transitions much better than the nexstar eng.had my brother take it off and get it trimmed out on first flight and he had a perfect landing.then he got her off the handed me the box,it flew a lot different than my nexstar but i got the feel of it and started getting it lower and lower on the runway,but we had some wind and i let him land each time.i have around 25 solo flights on the nexstar and am using this plane to transition into my h-9 corsair, which i'm scared to fly.i would not consider using this plane as a first flight plane,it seemed to really fall in the corners and the controls were very responsive compared to a true trainer. now this is just my opinion and i have never used a buddy box.balancing required us to move the battery behind the servo tray.when we unloaded it i noticed a rattling inside the cowling and we found that a eng. mount bolt had fallen out.cant wait to fly it again......[:D]

Seattle, I'm adding a pilot, headrest, etc, to mine. I think 1/9 scale should be your choice. Mine's a bit larger, but hey!....it's a sport scale trainer! The canopy comes off easily with the aid of a thin sheet of plastic, such as the dummy credit cards Discover sends out. You could use a laminated drivers license, as long a edges are not rough or sharp. Carefully separate the canopy from the fuse and carefully peel the glue off both. I'm using a deck of thin ply to fasten the pilot to, which in turn will be attached to the "floor" with servo screws (drill 1/16 pilot holes being careful not to hit anything below). Use canopy glue to re-attach.



stallwart -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 1:48:58 AM)

You know, a drop of threadlock during manufacture of RTFs would be an easy and relatively inexpensive way to take care of that problem. For a beginner to remove the engine, re-install with correct thrust line, or to even be aware of any of this is not likely. I'm sure most clubs educate beginners about these sorts of things but how many people fly the first few times without this awareness?

Thanks for the additional info. It sounds pretty easy to get the canopy off. Painting up and mounting a pilot will be a fun little project to add to the scale appeal of the airplane. :)

After racing nitro 1/10 scale on-road cars for the past four years, I've learned the "if it's a metal to metal connection, threadlock it!!!" rule is a valuable one. When my plane arrives I'll be going over everything and threadlocking where appropriate. So far I've already read about muffler bolts, engine mounts, and wheels coming loose on people with the P-51 PTS heh. [;)]



Mike3579 -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 2:54:20 AM)

Well got my mustang done tonight and it looks nice but I quickly learned that there is something wrong with the radio system. Working the sticks does nothing, all it does is go crazy. All the surfaces move and basically go nuts. I've never had a JR radio system. I only ever flown futaba radios but I do use JR servo's in my giant scale planes and have never had a problem. Guess I will call Horizon in the morning. [:@]



Casedit -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 2:17:28 PM)

Not sure if anyone else has this but my fuel line into the carb (blue hose into needle jet) rests against the cylinder head. Was thinking of using a couple of these to protect it from the heat...

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJF20&P=7

Not sure how these will stay in place, Anyone know of any heat shields that shrink around the hose like regular heat shrink tubing but with heat protection built in?



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 3:55:04 PM)

Casedit,
The silicon fuel tubing should not melt, so don't worry about it or spend your money needlessly, just keep an eye on it abd chande it out if needed.

To guys who have removed the droops,
I removed mine this morning at 6am to iron all the wrinkles out of the covering. It's 11am and I'm still trying to clean the residue off the wings and droops. I tried mineral spirits and denatured alcohol and it is still not gone, any ideas?

Thanks on the tubing...

As for removing residue, I use WD40 and has always worked great for me

pressurerat -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 4:14:10 PM)

Use lighter fluid....also called naptha. It's the kind one would use for a zippo . I also use a product called Goof Off but I think it is really just naptha. Try it; it works!



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 4:29:00 PM)

Thanks Guys,
I have some of that stuff and never though about it. This is not like I have never done this before. this residue just keeps smearing and smearing, but little by little it does come off. Just have to make sure that there is no residue left before I put the heat to the covering. Did make some progress today and got the flap servo installed. So far I have better than two days invested including fixing all the problems. Not bad for something touted as from box to the runway in less than an hour [:D].



Mike3579 -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/13/2005 6:31:01 PM)

I use "opps" from wallmart it will take that off and wont hurt the covering. Called horizon about the radio trouble and I have to send the radio and reciever back to them. I put one of my own recievers and put the plane on my 14 MZ radio. I will probable sell the JR radio when it gets back.



tr21triton -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 2:20:51 AM)

for anyone new to this hobby please pay attention to the page on balancing or your p51's first flight will be it's last.mine had to have the battery pack moved behind the servo tray to balance out.if it had ever got off the ground we probably wouldn't have gotten it back in 1 piece and i'd of been in tears.[sm=crying.gif][:(]



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 7:37:51 AM)

tr21triton,
Here's a thought for you for later on maybe. Horizon sells a prop drive thrust assembly that replaces that heavy flywheel that the engine comes with. It is inexpensive as I called and ordered one yesterday along with a couple of other parts. That alone will remove quite a bit of weight dead off the nose. Then add a two blade prop and spinner and get rid of some more weight. I was going to use an APC, but will try a MA first as the prop itself is lighter.

Guys,
Thanks for the tip on the WD40 worked like a charm[:D].



MMcConville -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 3:52:15 PM)

The CG on the Mustang is pretty broad. Being a bit nose heavy like you describe would nt have caused any problems. No need to move the battery pack behind the servos.



olstoney -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 4:13:17 PM)

Mike,
Not sure as the manual is not handy at the moment. I think the directions allow + or - 1/4" is this correct? Also where are the thrust angles for the engine measured from? The does not seem to be any built into the firewall and my engine is sitting square in the mount. Thanks



tr21triton -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 8:39:07 PM)

mike
i didn't want to take a chance with such a beautiful plane,so we balanced it to the book.sure wish the simulator had a usb adapter though, because i haven't been able to use it on my computer.just added a flap servo to it last night and that was a simple task,only about 15 min.hope to fly it again next week.



SeattleFlyer -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 9:21:37 PM)

My P-51 PTS arrived today and I'm happy to say it looks like everything made it safe and sound through the shipping. I ran it home on my lunch break and got the radio and receiver charging and I'll start putting it together in the next day or two.

A couple of newby questions for you guys:

1. The covering has some bubbles which I'd like to take care of. The manual recommends using a heat gun or a covering iron. I don't think I'll be covering an airplane any time soon so I think I'll pickup a heat gun. Do I need to order one specifically designed for model airplane use or if I pick one up at a hardware store will these do just as well? If so, what type of heat range should I be looking for? Any tips on doing this? I don't want to melt a hole through it or anything!!

2. I want to remove the engine cowel and the engine so I can a) fuel proof the firewall and b) thread lock the engine mount and muffler screws. A quick glance at the engine cowel had me wondering how to get it off as it looks to be 1 piece with the muffler and stuff sticking out of it. Any tips for disassembling this stuff?

Thanks in advance! [:D]




jlank -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 9:56:19 PM)

Seattle don't use a heat gun from the hardware store they are way to hot. Pick one up from the hobby store and be careful you can melt the covering if stay in one spot for to long. Try one like this http://www2.towerhobbies.com/cgi-bin/WTI0095P?FVSEARCH=heat+gun&FVPROFIL=++&search3=Go

Casedit -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 9:59:16 PM)

I used a blowdryer with one of the wife's attachments on the end - you know the kind to make it narrower... worked fine for me



tr21triton -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 10:00:59 PM)

dont know much about covering,my brother has a special iron for that.the cowling is a not too hard to remove.you nedd to remove the muffler by removing the 2 allen head screws 1 on each side of the head.then work the cowl around the head to remove it(its tight).had to remove mine to lock tight the eng screws.



SeattleFlyer -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/14/2005 11:02:58 PM)

Great. Thanks guys for the info / tips.



Steve Campbell -> RE: New Hanger 9 p-51 mustang **Trainer?!?** (9/15/2005 2:28:39 PM)

SeattleFlyer,

UltraCote needs 350 degrees or more to shrink fully. You won't get that from any personal hair dryer. One such WILL shrink the material somewhat, but it will bubble/sag again when it gets out in the sun. You need high heat to keep it down.

OTOH, jlank is correct in that commercial heat guns are TOO hot; as in melting the material or even scorching the underlying balsa. Your best bet is to buy a tool designed for the job. If you simply won't do that, for whatever reason, use a household iron on high setting, and place a thin cloth over the material before ironing.
