I used two actuators and two separate knobs to adjust the position of the boom not only vertically but also horizontally.

I made some improvements, and recorded a video showing the mechanical functions. http://www.youtube.com/watch?v=Fh88CawPtIE

I read almost all of the discussion, but did not find the answer to my question. What is the allowable percentage of use of parts in the model B? Should I try to use the maximum number of available parts, or better to focus on the model B was the best possible light and clean? If I remain a lot of spare parts, do I try to use them as decorations for the model B, or the number of remaining components is not critical?

I do not see any problem. in extreme cases B-model can be assembled with a single actuator, and the second will remain in reserve. I am surprised.I did not expect that someone has already built almost the same model. Moreover, with only one actuator for the boom.

Мy son (4.5 years old) tested the model on the playability, durability, handleability and was completely satisfied. I believe that it is necessary to have a break for New Year holidays, and begin to build a model B next year.

Another sleepless night, and I completed the lift with a basket (or a bucket?). I had to lengthen the handle (HOG) on the roof, because otherwise the boom is not allowed to twist it. The lift rises by two actuators (large and small) and rotates on the turntable. Maximum lifting height of about 50 cm. The model fits into the frame with a size of 15 * 18 * 37 (9990 cubic stud), and there is a small margin (about 1 stud) in length and height. I think this is the final version, and there is nothing more to improve. I ask your advice on how to better: frame the entire gray or red side stand? I am inclined to the version with red stands.

I think my cabin is not very similar to the GAZ-3309, so that it does not matter, there is a fire truck like this one or not. I spent half the night for modeling and made retractable legs and a base for the lift. transport position: middle position: fully expanded: worm gear, angular gears and axles:

I found a truck that looks very close to what I imagined. BC-18A on GAZ-3309 chassis. This scale model, but I'm sure there's a real prototype.

Unfortunately I do not have red axial connectors №3 so I had to make a window frame in gray.

Hi there! I hope not too late to create a discussion. I decided to build a fire truck with a ladder or bucket lift. Yet ready only cabin and frame with wheels. Some more pictures: front view doors open, seats and steering wheel inside

Seats is too small and ugly for this car.

Nice begining, but still so far from the model B...
