    Introduction

    The P-51 Mustang was the most famous fighter of World War II was the first fighter capable of escorting bombers deep into enemy territory. In 1966 Miss America was purchased as a stock P-51D and given the Miss America paint scheme. Miss America is a true legend, and an icon in American Aviation history.

    World Models Manufacturing Company is now producing the Miss America in an 80.5" wing span ARF.

    Out of the Box
    Fuse,Cowl,Scoop,Spinner
    Wing and Tail Parts
    Mustang Box
    The Mustang arrived in a large box. Everything in the box was in good condition, except for one wing tip with a few dings in it. I shrunk the covering and it looks fine. All hardware was complete. Some items worth mentioning; the retracts were already installed and are designed well. Also supplied in the kit was a clear temporary cowl used as a template for making the cut outs in the painted cowl. All that's needed to finish the Mustang is fuel line, radio gear and engine.

    Wing Assembly
    Wing and Tubes
    Wing Halves Hardware
    World Models designed the wing on the mustang as a two-piece, plug together wing. The wing is joined together by two aluminum tubes, and then bolted together by the supplied 90-degree angle brackets. The angle brackets are first bolted to each wing half. Then, slide the two wing halves together and the other bolts then go through the other half of the angle brackets drawing the halves together. This feature is very nice for being able to transport the mustang in a smaller vehicle. The ailerons and flaps come all hinged and glued in place. The hinges used in the mustang are an all-metal hinge that should be very durable.


    Wing Servos

    The aileron and flap servos are very easy to install. First remove the servo bay covers, which are just taped in place. The servos will be mounted to the servo bay covers. Next look in the manual and it will show what the balsa blocks look like that will be needed for mounting the servos. Use a servo as a template for gluing the blocks in place. After gluing the blocks in place, make holes for the servo screws. I recommend wicking thin CA into the holes, as this will harden the wood and help the servo screws stay tight. The flap and aileron servos will mount on to the wing servo covers the same way. When installing the servos be sure to you look at the servo covers closely, they need to go in certain locations so the ailerons and flap servos go in the right direction. The aileron servo outputs need to be opposite of each other, in order for the ailerons to work correctly. When the servo outputs are opposite of each other this will make the ailerons work opposite of the other. With the flap servos, the output arms need to face the same direction, so the flaps will move in the same direction together.


    Aileron and Flap Linkages

    Aileron Linkage

    Flap Linkage

    The aileron and flap linkages are very simple to make. All hardware is supplied in kit. After the control horns are installed, hold the controlling surface in the neutral position and get a measurement to the servo. Make a 90-degree bend in the wire; this end will go through the servo arm. The other end will hook to the control horn with a clevis. Make sure, after the linkages are made, there is no binding and the servo can actuate fully, without hitting on servo the arm opening. It may become necessary to increase the size of the opening. Be sure to install on the linkages the supplied small pieces of fuel tubing. These ensure that the clevis cannot open up and come off.

    Retracts

    Retract Up

    Retract down

    The retracts are already installed in the wing. They are robust in size and are mounted very solidly. At the wheel, the strut was designed to have some give built into it for hard landings. This can be seen by the U shaped bend next to the wheel. Another nice feature of these retracts is there is no need to use a retract servo.

    The retracts, have a spring inside them that assist the servo as the wheel is coming up. In the instruction manual World Models tells how much travel is need from your servo to fully actuate the retract mechanism. This can be accomplished with a large servo arm. If for some reason you should bend one of the retract strut, there are procedures in the back of the instruction manual on how to straighten them.


    Outer Retract doors

    Outer Retract doors

    Follow the instructions manual when installing. Use Household Goop adhesive on all parts when assembling. The Goop adhesive will dry and stay flexible, which is useful if the retract doors should bumped or have a hard landing.

    Retract Servos

    Retract Servo

    Servo in Up position

    Servo in Down Position

    The BMS-620MG servo from Blue Bird was chosen for the retracts. It has all metal gears, double ball bearings and produces 120 ounce inches of torque. The supplied control horns with servo will give the needed throw for the retract to actuate fully. The Mustang uses two servos one in each wing half. All necessary hardware is supplied.

    Engine & Cowling Installation

    Engine Box Side

    Engine Box

     
    The Supertigre G2300 was chosen for the review; it has a displacement of 1.40 cubic inches or 23cc and develops 3.7 horsepower @ 12,500 RPM. Weight with muffler is 37.65 ounces or 2.35 Lbs. The suggested prop sizes from Supertiger are 18x6, 18x8 and 18x10. The 18x6 Master Airscrew, Classic was chosen for the review. A lighter pitched prop will to let the engine RPM be higher.

    Engine Mounting

    Engine Mounts and Hardware

    Engine Left Side

    Engine Right Side

    The engine mount that is supplied in the kit is an anti vibration type mount. There's a little more work involved with assembling the mount and installing the engine in the mount. When ready to install the engine look at the instruction manual carefully. A noticeable difference in the mounting procedures is you will be drilling out plates that clamp to the engine mounting tabs. It is not necessary to drill the engine mount itself for it is already done for you. After having the plates drilled, then bolt them to the engine with the rubber anti vibration pieces between them. Once all the pieces are bolted together it is time to install the engine. In the motor mount hardware there will be many brass shims. Pay close attention to which ones are needed. It will depend on the size of the mounting holes on the engine. Use the brass shims where the bolts go through the rubber and the mount otherwise the bolts will pull through the rubber and not be tight.

    Muffler Mounting

    Muffler Opening

    Muffler Mounted

     
    A slim line muffler was used for the review. It is an inverted Pitt's style. The firewall had to be modified for the muffler to have clearance. If the recommended engines are used then skip this step. The firewall was cut to give ample space around the muffler, them boxed in with 1/16 plywood. There was no concern with the firewall loosing any strength. It is installed very well and there is plenty of material.

    Cowling

    Engine In cowling

    Cowling Screws

     
    The cowling on the Mustang is nicely painted. The color lines line up very nicely with the covering. A nice feature is the cowl screws and rubber washers. These little rubber washers' work to hold the cowling tight. It is not necessary to tighten the cowl screws very tight, they act like a rubber mount and let they cowl move slightly without it coming loose or being damaged by the vibration. The mounting holes in the cowl parts are already drilled making installation very easy. Also World Models supplies a clear plastic cowling to make cutouts in first. Then once your satisfied with your fit and openings you slide the clear plastic cowl over the painted cowl and the cutout and openings will be perfect.
    Engine break in and Performance

    The Superetigre G 2300 is a well made engine. The first time I started the engine, I primed it like normal, hooked up the glow starter and it started right up and sat there idling. After three tanks of fuel the engine it was idling very reliably and I felt that it was ready to flown. I used the 18x6 prop for break in and flying. The Supertigre G 2300 turns the 18x6 Master Airscrew classic prop at 8300 rpm's, even with the engine not broke in. One note about the engine, if you use another muffler other than the stock muffler, make sure that the outlet on the muffler you choose has the same size as stock muffler. The engine needs to have the correct backpressure and fuel tank pressure to run properly. The G 2300 is a nice power combination for the Mustang. Use a Slim line inverted Pitt's style muffler and there will be no engine components outside the cowl, giving the mustang a nice scale appearance.

    Fuel Tank Installation & Set up

    Fuel Lines Exit

    Fuel Tank Mounted

     
    Before installing the fuel tank, decide between a two or three line fuel system. For a two-line system, disconnect the fuel-line off the carburetor each time the tank is filled or emptied. With a three-line system there will be a separate line used for filling and emptying the fuel tank When installing the tank make sure that the motor mount bolts aren't sticking too far out of the firewall. If so, they could puncture a hole in the tank over time, from the vibration.

    The fuel tank installation is very easy. Because of using the inverted Pitts style muffler and having modify the fire wall slightly, The fuel tank will have to moved back slightly from original location. Just follow the instruction manual and you will have no problems. One nice feature with the tank installation is the tank stopper protrudes through the firewall leaving all fuel lines visible from the front.

    Installing Fin & Rudder, Stab & Elevators

    Stab and Joiner Tubes

    Stabs Joined

    Vertical Fin Installed

    Installing the tail parts was very easy; they aligned perfectly and took very little time. The horizontal stabs are designed so that they can be removed, making transportation much easier. The instruction manual says to glue the joiner tube into one half of the stab. After installing stabs on fuselage, there are two supplied screws that go through the stabs and into the fuselage. World Models has already installed the blind nuts in the fuselage and they line up very nicely. The vertical fin is glued in to the fuselage. The rear of the fuselage is designed so, that the rudder post will slide into the fuselage halves and it will hold the fin in place. As a suggestion to make sure that fin stays in proper alignment, use masking tape to hold still. The instruction manual tells what steps to take to make sure you have proper alignment.

    Control Linkages

    Elevator, Rudder Pull,
    Pull Hardware

    Assembled Pull, Pull

     
    Pull, Pull Linkages
    The rudder and elevator linkages are a cabled pull, pull system, which will need assembling. Follow the instruction manual carefully when assembling. There are illustrations showing how the wire must be looped around the brass bushing, and then crimped. One word of caution when assembling the pull, pull system. Make sure that the servo and controlling surface are centered, so the length of the cable will be correct. There is only one opportunity to make it right. Once made, its permanent.

    Elevator Linkage Hardware

    Elevator Linkage One Side

     
    The elevator linkage is made up of a shaft that passes all the way through the fuselage with control horns on the inside and outside. The pull, pull cables for the elevator connect to the control horn on the inside of the fuselage.

    Elevator Control Horn

    Elevator Linkage

     

    Once the elevator linkage is installed in the fuselage it's time to make the short wire linkage going to the each elevator half. One nice feature about this system is that it makes leveling the elevator halves very easy.

    Rudder
    The rudder pull, pull system is also easy to assemble. Follow the steps in the instruction manual. Remember to make sure when assembling the pull, pull system that the servo and rudder are centered. The cables can't be taken apart and made over.


    Servo Installation

    Elevator, Rudder Servo Mounts

    Elevator, Rudder, Servos

     
    The servo mounts are already made. One mounts in the upper front position and the other in lower rear position. The upper front servo mount is for the elevator. Mount the lower rudder servo mount first. If upper servo mount is put in first it will interfere with mounting the lower.

    Throttle Servo Mounted

    Throttle
    A HS-85 servo was used for the throttle. By using the smaller servo it's possible to mount the servo more forward in an area that wasn't meant for a servo but fits very well. This puts the servo closer to the engine and a shorter throttle cable can be used.
    Radio set up
    The radio I chose is the JR Xp 783. I felt that it would be a good combination for the Mustang. The receiver battery is a 2500mah 5 cell Nimh pack. I wrapped the battery and receiver in foam and installed them where the instruction manual recommended. Next I ran the antenna out the bottom of the fuselage. All control throws were set according to the manual. The rudder is 41mm each direction from center. Elevator 18mm up & down from center. Ailerons are 12mm up and down from center and flaps are 50mm down for landing. It has not been necessary to make any changes from these settings since flown.

    At the Flight Line

    Take Offs
    On take offs you apply a little up elevator. Advance the throttle to full and be ready for any rudder corrections that might be necessary. The rudder on the Mustang has real good authority, so be careful not to over correct. As the air speed increases the tail will lift and the Mustang will roll on the main landing till ready to fly.

    Landings
    The Mustang lands very nicely. Always remember to keep the airspeed up especially when using the flaps. The mustang will fly very slowly with the flaps on fully. When not using the flaps the Mustang will land much faster and stalling is more abrupt. When ever the Mustang would stall, it always went to the left making it very predictable.

    Flight Performance
    With the Supertigre G2300 there's plenty of power to do most aerobatic maneuvers. The Mustang flies at a nice scale speed with plenty of power to pull it through scale looking loops. With the recommended control throws on the ailerons rolls are very scale.


    Weight & Balance
    World Models recommends the Center of Gravity to be 6.9 inches behind the leading edge of the wing at the fuselage sides. Always remember the Mustang is low wing airplane and should balanced up side down. With the G2300 there was no need for any additional weight for balancing.







    Summary

    The Miss America Mustang is great flying and nice looking stand off scale Mustang. It looks like a real Mustang in the air and flies like one. The Mustang comes with good hardware, nice scale spinner and painted pilot. It's a good value for the money.

    Follow the instructions in the manual when assembling and you should be happy with the results.

    Is the tail wheel scaled (in the fuse) or is it like the other World Model mustang (Where the tail wheel is on the rudder)?
    Posted by: lynnb on 06/17/2008
    The scale tail wheel is my design. Yes the stock tail wheel is on the rudder. If you would like I could give more information on how to make the retractable tail wheel.

    Hi Still learning how to navigate this page Just bought the same plane although variant A100S1, not miss America. can you also send me the details on making the forward retractable tailwheel. Also how did you cover the retractable servo access hole. there is no provision for a screw on plate or instruction in the manual
    Posted by: David R on 05/08/2012
    Hi Again I see a difference. your servo location is in the centre of the wing hence inside the fuslarge. The location on mine is 8 inches ouboard each side from the wing centre line past the taper. Seems they changed the design
