Tamas Juhasz posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi all! I present my newest project, which is among my biggest ones ever. I build the monstrous Maz 535, inspired mainly by real life Maz (537, because there are no working 535 any more, if I know well), and a bit of Spintires. I know about this heavy truck before spintires, too, but when the tech demo released, I could finally "drive" it, simulating a bit the behavior of this truck. It's an awesome and indestructible machine, a real russian cold war truck. So it shouldn't be missing from my mocs. I build in 1:15 scale, which means the 108 mm tyres. Of course, in this size I'll use again the crawler tyres, RC4WD rock crusher XT's, and maybe later I'll buy a more authentic looking military tyres. I'll make the tractor truck, so there will be no cargo platform in the back. The real life vehicle: ---> this will be my version Thanks to spintires, we have some good looking high quality render, so I can make the details properly: http://www.simulasyonturk.com/wp-content/uploads/2012/10/spin-tires-maz535finihmodel1.jpg http://2.bp.blogspot.com/-1Lya0MYqf-I/UJXplkmcyuI/AAAAAAAAALQ/aKsF8vN25O8/s1600/maz535_04.jpg http://4.bp.blogspot.com/-oRD07JncgzY/UJXpgYwP83I/AAAAAAAAALE/A1tpVtJo1Gk/s1600/maz535_03.jpg https://i.ytimg.com/vi/sRDnX2OQ37I/maxresdefault.jpg My goals: - 1:15 scale --> 108 mm custom wheels - 8x8/4 (first two axles steered) - Radio controlled with RC buggy system, 1 RC unit, 2 RC motors - very robust drivetrain and steering - proportional looking, with model body and details, as close to the original as possible - 24 studs width at the wheels and body - full authentic (independent in front and semi-independent in rear) suspension with minimum 2-3 studs of suspension travel - no portal or planetary hub - 2 speed gearbox controlled by the RC unit's servo - working towing cable, with heavy winch and hook (metal) - working headlights - dark green color There will be pictures about the process soon, first I make the front axles and the main placing of components, steering. I collected a pretty large amount of dark green bircks, tiles, etc., so the color shouldn't be a problem. Fortunately, there are curved dark green bricks, to make the curved edges in the top and front. The gearbox would be a sliding type, and it's movement will be done by the servo of RC unit. To help in this process, and fix the slifing axle in the second gear's position there will be magnets somewhere. By default, the gearbox will be in first gear, when the servo is in 0 position, so it will be reliable under torque. The shifting to second gear this way will be an additional extra, if you want to do. It's a heavy truck (will be about 3 kg), so even with robust drivetrain I think it won't be capable of doing trial/heavy terrain, but if a medium can be done, that's far enough for me. If a 30° slope and a terrain with 3-4 studs high obstacles is no problem, then I reached my goal with it's off-road capabilities. Comments and questions, ideas, etc. are appreciated, as always.
