Good stuff, what do you think of the quality of the kit so far Kelvin?  
Show/hide user stats

 Hi David,

The build quality is in my opinion is excellent.

The wings fitted together perfect .

The tail is spot on,no need for sanding etc to get it all squared up.

May pin the control surface hinges just to make sure.

The covering is wrinkle free, apart from the wing tips.  It is well stuck down on the leading edges of the wings and very neat .

The only thing not very good is me with my epoxy fingers and cyno runs aaaargh .

Elevators and rudder next on the to do list.

Yes glue runs can be lethal on dark covering

Attaching the elevator and rudder.

Pins are used to centre the hinges.

The two halves of the  elevator are joined with a wire joiner using epoxy to glue into position.

The rudder is attached using thin CA .

The tailwheel bracket is  fixed into place with two screws.

Debonder will remove bad CA runs without marking the finish on the covering.

Nail varnish remover will work along with the debonder to leave the surface nice and shiny  .

Been a bit  messy with this mode l.

Retract  servo and linkage installation.

The mechanical retracts are already fitted in the wings all that is needed is to install the retract servo and connect the linkages.

Servo tray bay in the wing centre section

 The servo bay needed a bit of dremelling to remove the epoxy overspill.

The mounts straddle the centre section rib and rest flush to the wing sheeting on the inside of the wing

Servo tray glued  to the mounts with epoxy.

The control wires are trimmed and passed through the quick connectors .

3mm set screws with a little thread lock are used to secure the retract linkages

ooh yes, they seem to be set up nicely Kelvin

Very nicely done Kelvin. Just be sure that the servo over centres to ensure a good lock.

Installing the engine.

The metal engine mounts are secured to the fire wall by four socket screws and blind nuts.

The holes for the mounts are already drilled in the firewall.

View from insde the fuselage of the blind nuts.

With the engine removed the hole for the throttle push rod tube is drilled through the fire wall and fuselage former 2. It is then glued into place.

The throttle push rod is attached to the throttle arm on the engine and passed through the throttle tube.

The engine is secured with socket head scews and nylon lock nuts on to  the engine mounts.

Looking good Kelvin, i have one of these

waiting to be built, watching with interest.

Rudder and elevator servos are installed opposite sides of the rear fuselage, removal of the covering reveals the mounts  already  installed.

The ailerons are operated by two servos,one in each wing.(The string is to pull the servo lead through the wing).

http://i217.photobucket.com/albums/cc2/kelly2uk/P1010001-1.jpg

The servos are mounted on the hatch covers on wooden mounting blocks.

http://i217.photobucket.com/albums/cc2/kelly2uk/P1010002-2.jpg

The servos also need long servo arms in place of the standard ones.

Hi Kelvin

This is a great blog. Good photos too. I'd like to point out that this article is also very relevant to anyone wanting build the Hangar 9 Mustang. I've in the latter stages of building "Miss America" and apart from the wheels retracting differently, the construction is exactly the same. All of the servo mounts look like the same parts and hence are fitted by the same methods.

Nice scale looking exhaust ,if I could afford it .

I've spoken with Kelvin and He's happy for me to add some stuff here regarding the Hangar 9 Mustang and in particular the "Miss America" version I'm building as I've already said its very similar to his Warhawk as far as construction is concerned so I won't repeat his comments but add a few of my own that hopefully will compliment this article.

Here's a pic of my Mustang. I made the supporting tressle from central heating pipes and fittings

I have a  friend who made one similar to this some time back for his lancaster - used 4 X RCV engines. The exhaust was made up from small bore central heating pipes and elbows - was featured in RCME - few years back now....

Hopefully my comments will provide an alternative take on a warbird ARTF. Mine is a Reno Racer and so I've gone for performance. Whilst many full size warbirds are valuable classics and so are carefully cruised around at public displays to prolong their lives, I grew up near Rolls Royce Hucknall and vividly remember the sight and sound of their Spitfire being flown all out, howling at low level around the airfield and town. Its in bits now and being rebuilt at Filton so there's a lot to be said for the carefull approach taken by the BBMF and other owners of these classics! I've not done the maths, but even as the sound goes a high performance V12 can't be far off the "bangs per minute" from a healthy single cylinder two stroke.

Hucknall is also the place where the Merlin met the Mustang and so in the year where aero engine testing is due to close at Hucknall, this model seems rather apt.

I have decided that this model is for fun, howling around and looking great but with a good nod to scale items. Hence I have replaced the dash sticker with a "scale" decoupage dash with voltage gauges inplace of a dummy radio stack

The pilot is an ideal candidate for MIss America!

Here's a late pic of the inside of the fuselage. Its very similar to the Warhawk. Here everthing is positioned to work out the Cg for the first time hence the mess.
