Today, I would like to share my first creation on Eurobricks with you all. A model of a giant towbarless Pushback Tug. To be exact, the Goldhofer AST-1X 1360. The real vehicle can lift up the front landing gear of the biggest aircrafts. I tryed to build all the functions, how they are build in the real Goldhofer, especially with the rear steering. The model has 8 RC functions:- Front wheel drive (XL Motor)- Front wheel steering (M Motor) - Rear wheel steering (2x M Motor) -- I had to decide, whether I would like to have crab steering or steering with different wheel angles to allow smooth driving. In the end I've chosen the second option, because crab steering is still kind of possible.- Raise cabin (M Motor)- Pneumatic pump (L Motor)- Raise landing gear (L Motor)- Close lid (M Motor)- Fix landing gear (M Motor) Unfortunately, the model has some flaws. The cabin is lifted in a weird way, because of the battery box under it and I struggled with the lifting section. I had to use really strong clutch gears and worn out valves, and even with that, the valves didn't switch always. Also I had a problem with one of the pneumatic cylinders, the reason why I used two pumps. As a result I had to glue two 2L axle between the pumps to the red 1x2 thin liftarms because of the vibration. I was sick of searching for another solution . Here is a quick render, made with LDD and Bluerender.

Maybe I'll give that model another go in the future.
Hi all, as you might know I’m a car builder mainly, however, I’m interested in practically everything in the Lego City world, boats, trains (and monorail, of course!) included. One of the subjects I’m very fond of is Lego aviation. Of course, we won’t see those heavy brick-built aircraft fly high in the sky. But even grounded planes are quite interesting, especially passenger and cargo planes, just because of their size which allows lots of special functions you won’t be able to include in smaller vehicles. Plus an airport is in fact a place where lots of different vehicles can be watched: crash tenders, pushbacks, pallet and belt loaders, jet air starters, refuelers, extra-wide buses etc. etc. Since there are quite a few MOCs now concerning aviation I will put them together in this thread. This can also be regarded as a contribution to the idea of a more technical Lego city where any space available is used to include functions or light to get more interesting Lego City layouts. #1 Faun 8x8 Crash Tender (ARFF/FLF) 8w ARFF, equipped with 3 flashing lights (9 Volt Light & Sound) plus battery box. Fits 2 minifig firefighters. The Faun has its own thread: http://www.eurobrick...showtopic=96949 #2 Canadair Waterbomber CL-215 Wingspan 80 studs, weight 1050 g, equipped with 3 PF M motors (2 for the engines, 1 for the flaps), battery box and IR receiver. The rudder is coupled with the nose wheel. Fits 2 minifig pilots. Since 2014 the Canadair has undergone some changes, e. g. it has smaller propellers nowadays. Also the Canadair has its own thread: http://www.eurobrick...showtopic=95522 #3 Turbofan A possible design of a spinning turbofan with PF M motor I've developed some years ago: Sorry, I only have this blurry video of it. This design hasn't been used on an aircraft model yet, maybe I'll build something around it in the future. #4 Pushback/Tow Tractor/Aircraft Tug “Goliath” Not the most beautiful vehicle I've ever built, but it does its job: moving relatively large aircraft on a Lego airport which is rather rare to be seen, I guess. Equipment: PF M motor, IR receiver, battery box + Light & Sound flashing lights. Plus it has a storage compartment to keep the tug bolts. The pushback has a front wheel drive (with worm gear) and is able to push or pull Lego aircraft up to 1,5 kg (tested), maybe more, on a straight path - I wasn't able to build in a proper steering. More pics: Fixing the engine: Video: Thanks for looking, more to come (there's another aircraft in the pipeline).
