1/72 Monogram GRB-36D 
& Italeri RF-84K

In September 1981 an article was printed in Scale models magazine about the new Monogram B-36 and converting it into the Ficon. I really wanted to do it but I was only 16, lived with Mom and Dad had no money to buy it or space to put it. I bought the magazine anyway, as you do, and kept it for 21 years. Then one day I was in a hobby shop and there was the B-36 kit for $68. How could I resist? I got the F-84 and the Alclad and the rest is history. So after nearly a years work and more money on paint than the 2 kits combined and here it is.

 

The model is made from 2 kits, the Monogram RB-36H and the Italeri RF-84. The bomber was built as per the instructions but with detail changes and work done on the bomb bay. I didn’t want to rescribe the whole plane so I limited the amount of damage I was going to do to the raised panel lines which looked otherwise OK.

Starting in the cockpit the 2nd flight engineer was deleted as the D version only had a 3 man cockpit. The planes had the featherweight conversion so the nose turret and the gun sight blister windows for all but the lower rear were flared over. On the real plane this was a pretty rough job so I made the model with a glob of Milliput from the inside, smoothed over and an indentation made in the middle from a piece of squared sprue. After painting the indent was filled with Future and there you have a window. The rear bomb bay bulk head was moved back and the side wall structure extended using part left over from another kit made by Peter Vanderschaff many years ago. The main spar was fitted and a radio aerial purchased from an electronics store was mounted on the back of the main spar to act as the main jack. The rest of the trapeze mechanism was then built from by Peter Vanderschaff from brass, plastic rod and card to work in conjunction with the main jack. The rear of the front bulkhead was detailed with a window and the access trunk from front to rear of the plane was made from a piece of tube, the kit part now being too short. The D model also had a smaller tail warning radar and this was made by first removing the rudder then filing away the old fairings. A new cone was made from an old bomb and this was then faired in with Milliput before reattaching the rudder. I removed the rudder to prevent damage from the major surgery on the tail from damaging the raised detail.

 

The kit bombay doors were smoothed with Milliput and then cut to suit the shape of the F-84. I noted that one of the doors was only part length and the other full length. The fixed part was made from half a door and the short one was made from plastic card. The longer door was made of the 2 original doors. Both doors had a length of brass rod glued to the outer edge which formed the hinge mechanism. The fairing around the tail of the F-84 was done with plasticard and Milliput. Once complete and painted the fuselage was joined and the kit finished as usual. Other modifications to the fuselage included the homing beacon on the top of the fuselage and moving the 3 rear ECM fairings backwards.

 

With the fuselage completed I built the wings from the box but omitted the propellers. I blanked off the centre wings to prevent the see through look but otherwise they are stock. All seams were filled and polished before the Wing and fuselage were joined. When they were fitted you realise how big this kit is. I had to clear the whole bench to have space to work.

 

Normal filling and assembly continued as usual only bigger. Windows and glazed areas were masked and the whole model was then sprayed with black lacquer. Once this had a good finish I masked off the walkway on the upper wing and the areas around the crew stations and then painted the rest with Nissan Silver. The various shades of Alclad were then used to give the right panel tones over the silver paint. For the polished areas I used a mix of ‘polished Al’ and ‘normal Al’ as the polished look was too shiny. Once pleased I removed the masking from the windows and walkways and it looked like a B-36. 

 

Next step was the propellers. I had some 3mm acrylic sheet with a protective paper on both sides. I decided this was just the job so I marked a circle with dividers and cut out 8 discs on a band saw. I then drilled a centre hole and bolted them all together. I inserted the bolt end into a lathe chuck and spun it up at low speed which allowed me to use a file to get all the discs the same diameter and round! This was all very easy and only took a couple of hours. I then used an Olfa cutter to scribe a circle and remove the outer 5mm of the paper cover to clear the trace of the yellow tip. These were then sprayed lightly with Yellow. Once dry the rest of the mask was removed and the whole discs sprayed even more lightly with dark grey. The best 6 then made it onto the plane. I’ve never seen a truly good job of plastic discs representing propellers but I think these are as good as any other idea.

I built the F-84 about halfway through the B-36. This was ‘from the box’ but with a pilot figure in the seat and a brass hook added through the top of the nose before the fuselage halves were joined. During construction I drilled a hole through the fuselage and inserted a brass tube. This allows a pin to be passed through the F-84 to connect with holes in each side of the main trapeze mechanism. The only other change was to angle the tail planes down to suit the new aft bomb bay contours. The F-84 was painted in the same way as the B-36 but used as a prototype for the (new to me) paint process.

 

Due to the nature of the propellers and the fighter, it is impossible to put the thing down other then propped against a wall. (it is that big) so I built a small tripod to sit under it, supporting the bomber under each wing and enclosing the tail turret.

 

The kit decals were used for national insignia and titles. The numbers and codes were printed on my home inkjet printer onto clear film. The chequers on the fin and nose bay were again printed on the inkjet onto white decal film.

 

The inflight pics were montages done with Paintshop Pro and picture the combination in flight over New Zealand.

 

Thanks to Peter Vanderschaff for the trapeze mechanism. My soldering skills were never good enough to build that fine detail with enough strength. Also thanks to KE Duffey whose article in September 1981 Scale models inspired me to start this project those many years ago.  http://www.flankerman.fsnet.co.uk/ficon_modl.htm
