The WM P-51 is 80" and I thought this Fuji engine would give plenty of power:

I read someone put in a ZDZ 40 but the Fuji is less expensive and doesn't require nicad ignition.

What do you think and what have you seen others power the Mustang with in gas?

Thanks

I am willing to be proved wrong but I doubt that you will fit that engine in the cowl. I have a zdz40 in mine and it is just a snug fit. The zdz 40 weighs 3.15lbs with ignition compared to the fujis 4.62lbs, quite a difference without mufflers. The fuji has a side carb and side muffler which is huge, you would need to buy a good pitts muffler too, you would have pieces sticking out both sides. The final part is the length, at 6.84 inches the zdz needed 3/4 inch added to the firewall to bring the prop to position, with the fuji at 8.5 inches you would have to move the firewall back one inch to get correct position, quite a hack job. All in all not a great deal when the power is comparable, zdz 40 with 20x10 7200rpm, fuji 20x10 7100-7300.

The zdz will work out about 70 bucks more with a 1600 nicad. well worth the difference.

good luck whichever way you go.

I HAVE HAD QUITE A FEW OF THESE PLANES ,
RUNNING 2.10 MOKI'S, ST4500, BUT FOR GAS THE ZDZ 40 WAS MY FAVORITE, BUT IF YOU WANT TO KEEP THE $ DOWN ,I HAVE HAD GOOD LUCK WITH Q-40 -Q-42, AND ZENOAH G-38, AS THEY HAVE REAR EXHAUST, LESS CUTTING OF COWL, AND IT EXITS UNDER THE BOTTOM, YOU WOULD NEED TO CUT A HOLE IN THE LEFT SIDE ONLY FOR THE CARB. AND NO HACKING UP THE FIREWALL, WITH THESE ENGINES, AS THEY DO FIT.....
THE LATTER ENGINES MENTIONED DO FLY THEM WELL AS THE PLANE IS FAIRLY LIGHT.
GOOD LUCK......RUDY

ralbitre, what type of prop were you using with the Moki 210? I have the same set up, but I have been waiting about a month for slimline to make my inverted pitts muffler for it. Also did you use the stock tank and how long did it run with the stock tank if thats what you used?

I too have seen this plane being pulled by a Moki 2.10 and BGX3500. Both to me looked equal in power and performance. I have also seen it with a OS160. performancewas okay but not like the other two.

For the bucks I would go with the G-38 if only for the rear mounted muffler (and not the stock one)
I don't think you'll be happy with the power, were talking about a 16# plane with that engine.
My Miss America is at 14.2 with a Saito 180 and no frills.

Got a question, How does the 180 pull this plane? Can you compare it at all to a 160fx? BGX or Moki? Thanks

Sorry, I've never seen one fly with anything but a Saito 150 or 180.

The saito 180 has a lot less power than the OS 160 fx, so I would think that its the worse choice of the bunch. If are thinking about going with a 4 stroke because of the sound, trust me the 2 strokes are a lot deaper than the saito 180. The larger 2 strokes like the OS 160 FX and Moki's sound like gassers.

I'm looking into getting either the World Models GS or the new Hangar 9 GS.

What kind of performance do you guys get with the ZDZ ? The G-38 ?

I don't fly glow, so I cant guage the ref. from the glow engines to the gasers.

Thanks !

Koenig, check out this thread its shows the install for a zdz 40 in the WM mustang. http://rcuniverse.com/showthread.php...t=miss+america

Also I would suggest going with the WM mustang because it has an 80 in wing span the Hangar 9 wingspan is only 77in and it is not IMAA legal, so you could not take the plane to a giant scale meet, I have no idea why they didn'y just add the extra 3 inches.

ShoestringRacer

Thanks for the responses everyone. Looks like the zdz 40 she will get.

Paul and Rudy: What retract servos are you using? And what other servos on the plane as well. I just got the box yesterday!!

Sorry but the new H9 P-51 is 77" so it dose not qualify as "giant scale" were as the World GS P-51 is 81" and dose.
I have two World GS Mustangs, a Miss A. and a Ridge Runner.
I had one of the first H-9 60 size Mustangs that Sheldon"s received and sold it after a while still NIB because I thought it was too fragile and the landing gear was flimsy.
H9 did a absolutely beautiful job building and covering the plane but the structure was just too minimal, the World planes can take more of a beating. I hope they put a little more beef in the 77 incher and use real landing gear and not stuff from Toy's R Us.(I shop there for pilots and guns)

Hi there,
here is a link to my just finished plane. ZDZ 40, Hitec 5475 digital on ail, flaps. Hitec 5945 digital on rudder and elevator using stock bell crank setup with single servo on elevator. Hitec Hs75bb retract servos, when I had the wing upside down theses servos had a hard time retracting the gear against the assisting spring on 4.8 volts, it worked fine right ways up , just to be safe I went to a 6.0 volt pack and gave all my servos a boost. 114 ounces torque on retracts, 181 ounces on rudder and elevator and 76 ounces on ailerons and flaps. I have just got it together with a scale cockpit and a complete repaint, I am just balancing it now, check it out on RCU here.

Paul,

Your Mustang is a Beauty!

For the zdz 40 engine, did you use side or rear exhaust engine. Would you also tell me the make and model of the muffler you used on the engine. I got my plane now just need to get the gasser ordered.

Thanks,
Andrew

If you want to get fancy on the retracts , put in two hitec 5645MG digital servos and reprogram them. I slowed one of mine all the way down and the other 1 speed faster. Now I have slow sequencing retracts ! Cool. I know, most mustang come up even right ? Oh well, most don't know that.

My WM P-51 "Double Trouble II" is great. OS 1.60FX on electronic ignition w/slimline Pitts muffler turning a 3W 18X10 prop at 7600 rpm. Spring Air #404 retracts w/LiteFlite 1/2" struts. Also added wing fillets to finish off the look. Dry weight is 17.5 lbs. and yet flies very light. Flies at 85mph and looks beautiful in the air and on the ground.

Go to my website...

These photos are before test flights. It still had the original mechanical retracts and a Master Airscrew 18X8 prop.

Hey Spitfire,
I believe on the full scale Mustang that only one main wheel comes up at a time, so yours actually is very scale like with that setup.

I think I have narrowed it down to 3 gas engines.

The zdz-40, BME 50, and the Desert Aircraft DA-50-.

I'm not sure which way to go with the exhaust ? Building something custom should not be a problem but if i can get away with moding something already close then I would rather opt for that.

Anyone got any input ? Keep in mind I would like to hide as much as I can. I really dont want a big muffler hanging out, I plan to help this ARF with some scale detail.

One other thing, I have been poking around with the idea to convert this P-51-D into a P-51-B. Or should I even bother ?


Thanks Guys !!!

This is how the zdz40 fits with the supersonic muffler from rcs. nothing sticks out the side except for two 1/2 inch holes for the two muffler bolt heads which still come level with the outside of the cowl, invisible when painted.
Modding it to a type B would be quite a feat,almost as well getting a good f/g fuse kit.
Good Luck

Theres an article in the new Model Airplane News on painting iron on covering. The author paints a Great Plane's Fokker tripe and it looks GREAT. Thats all I can tell ya, left the mag at work last night.
