Here's the inverted OS91. The silencer was made by Just Engines to fit this model. It all fits inside the cowling but I've shorted the alloy tail pipes and fitted the silicon extensions incase of a belly landing.

Control Linkages.

The Rudder.elevator and ailerons all use the same method -Nylon clevises and nylon wire keepers.

Fitting the control  horn for the elevator.( same method for the rudder) .

Finished elvator linkage (rudder same).

Ailerons.

Finished linkage.

Throttle linkage.

Engine re-installed with throttle push rod fitted.

Pushrod connected to throttle servo arm with a quick connector.

Here is the Pilot Zach, named after my eldest Son.

Arranging a in- cowl exhaust system like the one Paul has  in his H-9  P-51,(see his photos above).

Not much left to do. Cockpit to finish, radio to install with seperate retract battery,  engine plumbing and  the cowl. 

As a personal preference I've replaced the tailwheel with an alloy hubbed version so I could retain it with washers soldered on each side of the wheel. I've also bent the rod sideways to engage in the control horn. This is more ugly than inseting it into the front of the rudder but isolates the rudder from any vertical movement of the tailwheel. The tailwheel can also be removed for maintenance. Also worth noting is that the tailwheel is completely wrong for a P51. If I have to do a rebuild I will consider moving it to the scale location and making it retractable

Here's a reinforced main gear bay with a home made control rod with a ball joint replacing the standard Z bend

Inside I have added 1/8 ply and balsa spars to carry the fuel tank batteries and reciever. The front set of spars also locate the fuel tank and are retained by screws into hardwood bearers so they can still be removed. I've also replaced the rigid throttle rod with a cable routed well to the side of the plane

 I have fitted a remote glow and fuel connector to an alloy bracket that is screwed to the firewall. The needle valve has been repositioned using a 1/4inch piece of hardwood bearer to move it sideways but maintaining its vertical position relative to the carb. Its visible on the above photos.

as homer says...

Cowl,spinner and prop  in place.

Cowl is held on by four screws, final fitting still to do.

 Cheers Timbo.

Test retracts  can be quite mesmerizing

I do like that Miss America scheme.  

Hi Paul

Not drilled  the holes for the screws yet, will let you know what I think.

Now I am coming to the end of the construction I would like to share my thoughts on the Warhawk so far.

Before I purchased the P-40 I did a web search to find out if  the warhawk was a good model. The opinions ranged from  horror stories of tailplane failure,firewalls ripping out and the U/C failing during landings, to others saying it is the best thing since sliced bread with no problems after many flights,  built as it is with no modifiications.

The firewall as I understand was a problem now modified by H9 .

The U/C failures may be due to heavy landings, poor landing skills or rough ground flying sites.

The tailplane failure may be caused by flying the model too hard possibly a vertical dive from altitude at full throttle with a sharp pull up at the end or stresses placed during non scale aerobatics,it is after all considered to be a semi-scale sports model .

One guy even thought H9  used hot glue for the consruction of the airframe,H9 pointed out it is the resin in the glue H9 uses which gives it the white hot glue looking colour.

On balance the vast majority of  people praised the P-40 .

I found the construction to be straight forward with very clear instructions with  nice hints added at the end of some sections. I have built as per the instuctions with the exception of securing the wheel wells with screws rather than gluing to allow future access to the U/C bell cranks.

If anything falls off  or fails to do its job, I shall report on this blog  .

This is the fourth ARTF I have constructed ,of the two I have flown ,one has needed modification (engine mount Ripmax Spit) so it may be the P-40 will need mods in some way..

Must send the info off for my exhaust  .

Cheers all

 I have "built" my Miss America in my Rc flight sim by modding the graphics, sound and data files of the default P51. Hopefully this should give me a rough idea of how it will look and handle in the air.

Cockpit finished, replaced panel with one from a flight sim c/o IL2 .

A few pics.

Cowl fitted ,screws not a problem so far, need to harden screw holes in the fusalage with cyno.

The cowl was difficult to line up due to the inbuilt side  and down thrust not a perfect fit but OK. 

Kelvin, with the nicely painted pilot and replacement dash that cockpit looks very good. With the rubbish weather over the weekend I've got plenty done on the mustang.

This is the switch I've bought to operate the undercarriage and radio circuits. With it are the 1/32 ply plates I've made to reinforce the fuselage and my circuit diagram, I will appologise for it as its twenty years since I last drew one and so the symbology may well be wrong but I just did it for my own reference.

This is the completed harness with outputs for the relevant voltage meters and sharing the negative wires except for the servo wich is earthed via its plug into the receiver and I thought just a signal wire could be vulnerable on its own. The connections to the switch ahve been covered in hot melt glue to protect them from vibration.

I fitted a paper tube over the wires to the tail servos to stop the wires thrashing around. Just a peice of A4 rolled into a tube PVA'd and then stuck in place with PVA.

Here's the fuel and glow system. Flushed the fuel system before connecting to the engine. Its a bit of a spaghetti due to the postion of the pipes on the refuelling valve, it would have fitted better on the other side of the plane but that would have been impossible due to the engine mount offset and the throttle cable

Two greens on the voltage gauges. Both circuits alive and tested

Looking ready to go

And finally, having landed safely after her first flight today. Control throws and C of G set up as per the instructions. I had some problems with the engine flooding when initially starting but soon set up with some help from another club member and a good test flight followed. Even though set rich, the engine produced plenty of power and the plane felt agile and light. Good response to control inputs and slowed very well for landing. Looked great in the air and easy to orientate against the late afternoon sun.

Now I've confirmed  the Cof G I'll spent some more time sorting the wiring and tidying up the radio installation.
