Details on the rotor blades and the engine. The rotor blades are made of sterene sheet softened in boiling water to stretch 'n' turn in a way to look realistic. Soft sanding applied on the blade's leading edge to be shaped as it should be. The spinner cone was made of an old 1/48 scale fuel tank tip, found in sparebox.

The controls in this two-seater model autogyro, as with any trainer aircraft, perform the same movements. Feel free to notice the rudder pedals and you will see that the front and the back seat, right rudder pedal is pressed to full FWD possition, bringing the left ruder pedal in full AFT possition . This has resulted in turning the nose wheel to the right and turning the rudder of the tail in such a way as to twist the autogyro to right as defined by the position of the rudder pedals. Also notice that the throttle lever of back seat is attached on a bar connecting to the front seat engine throttle so to move simultaneously. The engine's power transmission is made with a wire, launched by the front seat throttle lever and lead the assembly of the engine. Finally, the control sticks are fallen slightly forward, which of course means that the elevators are set in a similar position. Also notice that the position of controls (stick, rudder pedals and engine throttle) meet the relative position of the elevator and rudder fins, the nose wheel, etc. The front & rear seat rudder pedals perform exactly the same movements as linked to the same wire transmission. If you also check the rudder pedals position, you’ll notice right rudder pedals pressed front end, bringing the left rudder pedals full back. As an effect, the nose wheel turns to the right and rudder fin turns in a way to turn the autogyro to the right as defined by the position of the rudder pedals. In similar manner, both control sticks (which perform exactly the same movements as they are connected to the same bar drive) are positioned slightly forward. This has the effect of elevator fins rotation so as to oblige the autogyro in the descent, as defined by the position of the control sticks. In a similar position the main rotor head is placed as required. As it is known, the autogyros and the helicopters leans to the left or right, elevates nose up or descent nose down, by turning the main rotor blades disc and secondarily to aileron and elevator fins (if present) and turn to left or to right with the rudder fins (autogyros) or tail rotor (helicopters).

I’ve been asked about the available space where the rear passenger puts his feet on. From the pictures of the model have been published, and the art images found on the article’s first page, it appears that the rear seat is too close to the back of the front seat - and it is also clear from the blueprints of the real autogyro that it’s not my own assumption or a model building mistake. In real autogyro, rear passenger's feet are not squeezed behind the front passenger seat back, but they are placed left & right of the front seat! To make it more understandable, have a look in following pictures, showing a tandem cockpit seating positions as described:

[*]The green lines represent the front seat passenger and the position of his feet on the rudder pedals and
[*]The blue lines represent the rear seat passenger and the position of his feet on the rudder pedals.

As soon as the plaster cast got harden, cut into shape and the concrete plaques were lined with a scriber, I used my airbrush to paint it. After the polished wooden frame was covered with masking tape, three different acrylic paint layers were applied on the plaster surface. First, mat black colour covered the area and then a light grey applied with airbrush, spraying in almost zero degree angle, to let the darker areas between the concrete plaques remain naturally dark. The corner was paint with earth tones and as soon as the acrylic colours dried, I tried some drybrushing on selected spots using sand tones.

I also tried some camera shots with black paper background (instead of white) & different light conditions and I was surprised on how the model looks like. From now on, black background and low level lighting only...

PS. A little sparrow bird is now present on tail fin :D

If you see the following picture, it's not a problem caused by me or the file library which host the pictures. IMHO, I think that this must be a crash caused by modelsitesi forum, because I've never seen anything like this before. Also, keep in mind, that I see the exact same "problem" window, into other threads and articles written by other modelsitesi forum members.

Same problem here...

Pictures've been seen without any problem on ARC forum.

I wish I wouldn't :P .... I'm so jealous.....

Hats off to you Nick...

p.s. I saw your jaw droping f-16 project either.

CHAPTER XII - Aknowledgments
I would like to express my special thanks to:

[*]All fellow scale modelers, who have expressed their ideas through this forum and suggested solutions to technical issues encountered during this WIP.
[*]Mr. George Papadimitriou, owner of Hobby Gallery hobby shop and exclusive distributor for LifeColor & AK Interactive products in Greece, for his kind support and providing all the goodies I asked for - from A to Z.
[*]My sweetheart wife, who actively participated in the project as an indispensable assistant, offering me relaxing neck massage while working on my bench.

Finally, thank you all for following this thread and I hope you enjoyed reading this article. I’ll meet you soon, on my next scale modeling project.

Regards,
Nick
