Beautiful! Nice work on the casings. What are you going to do about the rubbing?

There is more to be added Max, on the front is a metal frame that helps to push the doors open and I will put a small plywood square at the final contact point.

Re: 71" Brian Taylor Mosquito Build

On the front of the casings there is an x shaped cross brace. On the real plane this guides some cables that pull the doors closed upon retraction. My doors are closed with small rubber bands but the effect is the same.



The cross braces are made out of 3/32" brass tubing with the ends squashed in a vise.



I have added in some 1/8" ply tops to the casings, this also gives a gluing surface for the cross brace.



In this shot you can see the rubber band that closes the door as the gear retracts. It is attached at the top of the front pivot and at the front of the gear door.



My friend Ward made some hub covers to simulate the brakes out of balsa wood.



A little bit of silver paint and everything is looking better.



Now I can add the front metal frame. it is made out of 1/16" and 3/32" brass tube.



You can see as the gear comes out the frame pushes the door open.




Of course the frame has to be done on the other side as well.



More silver paint and it is starting to look like the real thing.



A shot from further out.



And finally in this shot you can see the two hooks for the rubber bands. I have also added the rollers on the casings. On the real plane these help guide the cables described earlier.



Again at this point I thought that I was finished with the gear and should go on to other things, but the real Mosquito has fenders.

Re: 71" Brian Taylor Mosquito Build

On to the engine nacelles. In the first picture the fuel tank can be seen extending into the landing gear bay. This version of the Mosquito has a shorter nose and is cramped in the engine area especially compared to the 81" Mosquito.



One of the throttle servos can be seen under the fuel tank and right next to it is the muffler. I used some 3/8" copper tubing to make an exhaust extension. Later I split the tube and used a metal screw clamp to hold it in place. I affixed the pipe to the firewall with a strip of brass. The copper tubing almost touches one of the gear doors.



I had to sharpen the radius of the exhaust pipe that comes out of the engine. I heated it to red hot and used some drill bits as extensions to bend it. This gave me the required radius and allowed the muffler to follow the lines of the cowling.



This is the first trial fitting of the fiberglass cowling. Some of the required details in the cowl are missing at this point so will have to be added.



I carved the chin oil cooler scoop out of balsa and attached it. The fiberglass cowling is quite flexible, you can notice that I used spot putty to fill the gaps. Unfortunately it is not at all flexible. I noticed that in handling the cowl I was getting cracks in the filler. So later I covered the joint with fiberglass to minimize flexing.





I temporarily attached the spinners to see how everything would fit





In order to get more cooling air to the engine area I made holes in the sides of the cowling. The exhaust covers are carved out of balsa wood and scoop the air and deflect it into the engine compartment.





The exhaust covers have been attached to the cowl and were also reinforced with fiberglass to prevent flexing and cracking.

Re: 71" Brian Taylor Mosquito Build

Back to the fuse. When the wing is fitted there is a gap formed between the wing and the fuselage. The plan shows how this area is filled in.



The short kit had some 1/64 ply cover pieces that covered some balsa parts the I had to fabricate. Here is what it looks like at the start.



And here is the finished shot. After painting when the wing is fitted the gap is very small and the wing is actually a tight fit. I had to rub the parts with some candle wax (old fashioned method of lubricating that works) to facilitate assembly and disassembly of the plane.

Re: 71" Brian Taylor Mosquito Build

It is now time to drill the holes for the cannons. The mosquito had four mounted under the pilots feet. Imagine the feeling the pilot and the navigator had when those cannons were going off with only a layer of wood between them and the guns.
I carefully marked the fuselage for the holes and used a series of successively larger drill bits to make the holes. It is very nerve racking when you do this as these steps cannot easily be undone. Fortunately I inserted some blocks in the floor of the fuselage for these holes. I did not quite get enough but it was not an issue.



The procedure went fairly well but the second hole from the left gave me some issues. The oblique angle makes drilling difficult and you need long bits.



Here is the view of the holes from nose on.



The holes would need liners. I found some old telephone wire markers lying around, these are split plastic tubes that were put on wires. They are very springy and they fit the bill nicely.





After sanding they blend right in.

Re: 71" Brian Taylor Mosquito Build

Time to work on the cockpit. The cockpit area is cut out of the planked fuselage. When done it is a large hole. I used the canopy to get the basic shape and started on the small side. This way I can remove material incrementally. No going back from here. A lot of the bulkheads will also have to be trimmed to fit in a full cockpit. I thought of using bust figures and a deck in the cockpit but why not do it right. The pilot figures that I found only go to the shoulders but with a little carving they can be made to look like whole pilots.





In this shot you can see the pilot bust mounted on top of a carved Styrofoam body.



The navigator has room to extend his legs a little but the pilot does not.



You can see that I managed to clean up the opening quite a bit and removed most of the interior bulkheads. The pilot and the navigator do not sit beside each other in the Mosquito. The pilot is in front and the navigator is a little behind. It is not a wide cockpit.



In this next shot you can see how little of the fuselage side is left to support all the lead that this plane will need. At this point I wrapped the canopy in plastic and made a plaster of Paris mold for later work.

Re: 71" Brian Taylor Mosquito Build

The beginning of the cockpit;

I used documentation and photos that I found on the internet to come up with the instrument panel shape and layout. I had a sheet of pre-printed instruments lying around that I had purchased years ago. The back of the instrument panel is 1/64" ply and the front parts are made out of thin styrene sheets. I drilled the holes with sharpened brass tubing. The back of the panel was covered with some clear acetate. Using wire wrapped around a dowel I was able to simulate the bezels. The switches on the right side are cut off ends of wire ties.



When it is all put together it looks quite convincing.







Here is how it fits inside the cockpit.



I fabricated the pilots seat and the navigators seats out of thin plywood. The navigator did not really have much of a seat to sit on. The radio receiver was fabricated from balsa wood. the coloured knobs were carved from a piece of grooved doweling. The centre portion was cut from a photo of the real radio Receiver. The interior of the cockpit was painted with a mix of green and blue dope.



The transmitter was located behind the pilot and could be operated by the navigator. The face on this is also from a photo of the real thing.

Re: 71" Brian Taylor Mosquito Build

In keeping with the cockpit finishing I will continue with those pictures.
I have made arms for the pilots and glued them on. The pilots are being painted with acrylic paints. I made the seatbelts out of elastic from an old cockpit kit. A gun sight was fabricated from brass tube and some clear plastic that I bent into a prism shape. The mirror is a piece of metal duct tape. 1/16 ply has been added in front of the canopy area to simulate the armour plating. I have also added some details to the back of the cockpit by adding a panel for the cockpit wiring.



In the second shot I have added a navigator control panel. The navigator also had to watch some of the fuel gauges. It is easier to see the gun sight parallax correcting mirror. This means that even if the pilot moved his head around the sight would still work properly. I added buckles to the seat belt harness. They are made from washers with a dollop of black paint in the middle.



I added the pilots control stick and in this shot the navigators panel can be seen more clearly. The pilot is completely painted and the navigator is still waiting.





In my last post I mentioned that I had made a plaster of Paris mold of the inside canopy shape. I cut grooves in the plaster of Paris and used the shape to assemble a tubular framework of brass tubing and copper wire for inside the canopy area. The real mosquito canopy has a metal frame on the outside and also tubes on the inside.



I have added other details for this shot. The triangular gusset will hold the flare gun. The centre square area is an escape hatch, and the side tubes have been added. The canopy has had it's final trimming.



After finishing the painting of the pilots I put everything into the cockpit to see how it all fits and it is looking good.
