Hello all! It's time for update!!! Now all the mechanisms are complete, connected and working! The body isn't complete yet but you can see the inner structure :) Electrical schematic is here too. First post: A long time ago i've watched a program about this machine on Discovery channel. I spent a few monthes to the first version, but unfortunately i've choosen too big scale and it was fatal mistake. It was tough decision but i completely destroyed it. Now i started smaller version with all functions of the first one. RC functions (total 11): - moving - two-dimensional tilting - rotation - two-stage boom management - two-dimensional felling head management - two pairs of claws Manual functions: - lights - saw I hope it will be successful! Thanks for watching!

Very interesting model! +1 !!!!

Very original MOC! Good work!

Very interesting model! I like compactness of rotor transmission - very well done!!!

I've done building instructions for this chassis. It's my first expirience of instructions creation. Comments are in Russian but i think the pictures are clear!

Fascinating thing! I can looking at it for a long time...

Yes! When i got 8366 set i've tried to improve its drift possibilities (8366 have RWD). I've increased the wheelbase, changed buggy-motor output to slow and removed the load from motor pulleys. And all what i've received - the 180 degrees turns. Maybe it is real to do RWD drift car if select right weigh destribution, front wheel angle and so on but it will take much time and result can be still negative. BTW all professional RC drift cars are AWD.

it sounds very plausible! At the straight it's not visible but at curve we can see this result! Yes, AWD with all-wheel equal speed!

Something like this... I'm not sure that i completely understand the drift mechanism but i know that if i place locked rear diff instead of 1:1 transmission - it wouldn't drift. The same thing if i delete front diff.

Thanks for this calculation! The differential is mounted in the front, so rear wheels have more speed.

So, as i promised - transmission! The key feature is that rear wheels rotates faster then front wheels.

Thanks for interest! I'll create transmission submodel and post it today! No :) it's typical parquet. The only one cheat is insulation tape on the front wheels because i have only two smooth wheels and i mount their behind. With body and accumulators it weights about 1200 g Yes, it's really big - about 48 cm. I tryed to lock suspension and on the face of it there is no difference!

Hello All! Recently i've finished experiments with my second drift car (the first one drifted not too good). Please watch a video before you'll estimate its holed design :) Thanks for watching!

Very cool model and very interesting design!

Thanks! I've met steampunk not a long time ago, but it is a really amazing style and i have a big plans for it :)

I like it too and i am going to construct a few more technic models in this style :) No, there is no chain. i use two pairs of this - http://www.bricklink.com/catalogItem.asp?P=32072 In the future modification i'll add the reduction because the axes are exposed to very high load.

Thanks! Yes :) when candies were ended we started to grab stones, GoPro and many others...

Incredible functionality!!! I don't know what i like more - design or mechanisms - both are perfect! And presentation is very interesting too!

Hello All! This interactive MOC was created by me (technical part) and Cooler (design) specially for public festival and every guest tried to break it during long two days :) We call it “Claw” :) The words are unnecessary… Detailed photos: Thanks for watching!

Thanks!!! Best of all I like the working of 8466 rear suspension when i pulled it out of precipice :)

I can't see the pictures! Somebody have such problem?

Thanks! I've created short video! Also i've created my own youtube channel so if somebody was subscribed to my old channel - please resubscribe to the new one :)

Thanks a lot!!! Thanks!

Thanks for comments! I am glad you like it! Yes, CV joints are Ok. If rear wheels don't fit the trajectory there is another problem - the tires tend to fall off, but with careful driving it is not critical!

Hello All!!! After my holiday i’ve come back with new ideas, so there is the first one. I was inspired by Filsawgood’s Airfield Tug and decide to create my own version of this machine. I am glad to present a scale model of non-existent Heavy Multifunctional Aerodrome Tow Truck in a technic-figure scale. The model is 77 cm long, 23 cm wide (without mirrors), 13 cm high (without exhaust), the weight is 4,45 kg. It took me about 1,5 months to create it. Short video presentation: And winter test-drive: The model have eight RC functions (seven useful + compressor) and manual controlled winches and lights (total 12 motors). - moving (three XL-motors); - independent front and rear steering (two servo-motors); - lifting jacks (M-motor, eight pneumatic cylinders); - cab lifting (M-motor, two pneumatic cylinders); - front PPTO (M-motor); - rear PTO (buggy-motor, slow output); - winches (two L-motors); - light (twelve LED pairs). The transmission is very simple but rather reliable, one motor per axle with 1:3 reduction and differential gear. There are no safety devices in winches because I want to get maximum power. So i provide a fast-unwind mechanism. Winch hook is used like a movable pulley giving theoretically double gain in efficiency. All mechanisms are covered with protective covers. The accumulators turns on/off on the top of the model. There is a lightning switch in the rear part of the truck. The model have lightning around the periphery. Pneumatic is working due to four-pump compressor and RC valves. The lifting jacks are the old-type large pneumatic cylinders mounted on the chassis. Lifting cab function improves operator survey. It is very useful if we connect external mould-board. The mould-board height is controlled by using PPTO. Rear PTO is used for different attached implements. For demonstration I’ve constructed an external boom-crane (the length – 89 cm, width – 22 cm, transportation height – 19 cm, boom length – 95 cm, weight – 3,65 kg). We need to connect crane to the main tow truck for lifting jacks activation. Comfortable crane transmission creation was non-trivial task. I’ve took all the controls out to the operator cab (every lever changes the direction of its own function). Manual control allows to rotate tower, rise and extend the boom. At the small angles we need to rise boom with rear winch because actuators can’t conduct such big load. Another cool feature of the crane is wheels hiding. It is necessary because the wheels prevent tower rotation. I try on my white-stripped rims from 41999: More photos: https://flickr.com/photos/141718063@N06/albums/72157669696422836 Thanks for watching! Hope you like it!
