This is the temporary placement of the swashplate. It was quite a struggle to find a proper place. The whole model is 9 stud wide, and I wanna keep a wall of 2 studs to have space for structural reinforcement, so the rotor hole can only be 5x5. The problem is that the swashplate itself is already 5x5, so the liftarms that connect it to the blades must be directly above it. That means I need another one stud going outside to connect the 5 holes to the 5 liftarms, causing the structure to have a 7x7x2 space. And because the collective pitch is supposed to go up and down, the actual required space is 7x7x3. To complicate matters further, I need a liftarm that connects the landing gears in the front and in the back. So I put it in the seating area where there is enough space, and that means the 28z turntable has to be on the floor. And that means I'll have to find a way to connect the turntable to the rear rotor. That's a whole different problem.. If things dont work out and I get desperate I'll hollow out a full 7x7 column.

At this scale the model can only be 9 stud wide. The original area for the rotor is only 4 studs wide if it's to be accurate to scale. There's also a fence around the rotor hole. The new swashplate is 5x5 and with tow ball pins attached it will be 7 stud wide. So theoretically it might fit if I remove everything between the two walls. I think there is only space for a collective pitch if I put the swashplate lower in the body.

The general impression towards the original 42145, or at least my impression, is that it is an excellent Technic model in terms of functions and building experience, but not a really good replica of a real H175. Take the name away and it's hardly recognizable. Hence I've been working on a smaller 42145 that aims to capture the accurate proportion. The original model I worked on is motorized, and that's the source of the fun. The design challenge involve fitting a battery box + a motor + a two-function gearbox in a very tight place and building a form locked structure around them. It was very challenging and very satisfying to have arrived at a satisfactory solution. But TC25's rule does not allow electronics, and faithfulness in terms of color to the original model is one of the scoring factors. So I hollowed out its inside and changed it to this. At the moment I'm not sure of which color scheme I should go with. 42145's original color scheme is not very inspiring to me, and the color scheme I originally used is based on this, which is much cooler to me. Another thing is that without the gearbox and electronics the model is very boring inside. The winch is already manual. Now I only need to add a driving crank to the landing gear mechanism and the rotating blades. I guess in the end I'll just have to roll with it.
