The model is almost finished. I added more mechanical features.  But using the extra time, I will improve the exterior. What do you think about such variants of the front of the cabin?

The last one with three slats.
Maybe three slats in dbg could be an option too?

The model is ready. I'm just waiting for the missing yellow panels and stickers. I added several manual and motorized functions to it. For example, stop signs that open sideways. 12 cylinder fake engine, HOG, and others.

I really like this model! It's creative, and very nice and clean looking! One thing I don't like is the use of stickers for the window pillars, but I suppose any alternative is going to be very heavy on parts and probably worse looking.

Good job!

Thanks for the feedback. It is exactly as you write. I'm not in favour of using stickers either.  The sides are heavy and I had to keep an eye on the weight. But do not forget that this is not a model of a real bus. But the fake bus model has no real windows.

Yeah, I guess it does make sense that there wouldn't actually be back windows!

Wow, works and looks great! Only thing that is bothering me is the sound of skipping teeth. Any way you can do something about it?

Very nice! I liked the model before, and now that I watch the video I find that the transformation is significantly more complicated than I had assumed.

Great job!

Really impressive, well done!! Hopefully you’ve some time left to fix the skipping gears, then this entry would be close to perfect…

Thanks for the feedback. But what you hear is not skipping gears. This is the new clutch . And clutches in linear actuators.

That's just awesome, I love how the roof also folds down, not just left on the side. And that cabin tilt and rotation is a nice addition. Besides, it looks really cool as a bus, nothing suspicious :)

I went outside for a small photo session. What do you think?

The bus is inspired by Blue Bird vehicles. I focused more on a neat combination of technical panels than on the exact reproduction of the original. After all, it was about building a vehicle that was only supposed to pretend to be a bus.
For this reason, I also had no qualms about using black panels and yellow stickers instead of building posts on the windows.
Tilting sides had to be made of panels because with the length of the model almost 70cm and competition restrictions on the number of engines I could not overdo it with weight.
To build the frame I reached for the solution I used earlier in my URAL 5920 light rigid and with a small thickness of 3 studs.
On the frame is mounted a transfer gearbox consisting of two worm gears and gears that reduce the speed at the engine input and accelerate at the output on linear actuators.
It took me a lot of work to choose the gears in such a way that using only one engine to achieve simultaneous closing of the side sides, a rocket with a roof and tailgate. 

The key to success was the use of six pairs of z36 and z12 gears connected in the side lifting mechanism so that they could be moved apart throughout the construction period.
This solution enabled a very precise calibration of the closing process of all 4 elements. 

When I succeeded, I added a mechanism for lifting and rotating the cabin, both based on worm gears. Finally, I built a steering mechanism, a V12 engine and retractable stop signs, also on the screws. So the model has as many as 6 worm gears, my record. The sides after full opening adhere perfectly to the ground and form a very stable starting platform, so there was no need to install additional supports.

The mechanism of lifting the rocket after full opening activates the light brick, such a gadget imitating ignition. When the operator's cabin is turned in the take-off position, you can still quickly close the rocket to protect it from bad weather conditions.

The whole weight of 3 kg is 70 cm long and 16.5 cm wide and holds the proportions of the Blue Bird bus, maybe it is too wide by one stud. I did not manage to reproduce the rear bumper because the moving elements overlap and I had to fit there the "hand of God" to control.
I decided to start in the competition on December 20, the model was created basically in two Christmas weeks, then I was just refining the details and looking for the missing bricks

Body, this looks really cool. Does a school bus transform into a rocket launcher? What? That looks incredible. So far it's at the top of the craziest ideas I've seen here.I want to do something similar only not with the school bus because the school gives me only negative associations - I finished it only because I tried https://uk.edubirdie.com/buy-assignment-online end start to buy assignments online on this and similar resourses. I hope the situation will change at university and studying will become better, especially after quarantine.
