Hi, I would like to present you my first MOC prepared especially for official LugPOL Truck Trial Championship. MOC is based on very famous, polish truck with good off-road capabilities - Star 266. I choose polish truck to introduce some local technology to the competition dominated by soviet machines. Instructions are free of charge, so if you have parts and some time, you can enjoy off-roading with this model pretty easy. LINK Here are my priorities when designing this truck: to fulfill LugPOL Truck Trial Championship rules and to provide truck which will be accepted by judges to prepare truck with good off-road capabilities to build it to make it recognizable Couple of LTTC rules: scale: 1:12 to 1:14 number and type of axles true to the real machine type of suspension true to the real machine must be RC and all-wheel drive the truck's cabin true to real machine, with roof, seats, steering wheel, floor and with openable doors All above rules were fulfilled, below there are couple of more details: scale: 1:12 drive: 2x PF XLs coupled, if necessary, each wheel can harness power of two XL motors steering: PF L motor weight: ~1990g dimensions: W x L x H: 25 x 64,5 x 32,5 studs (width without wheels and tires) Star is powered by Buwizz 2.0, but since it uses only PF motors in very simple configuration, it can be powered by anything you have Truck was designed to work with 96mm Tamiya CC01 tires, and those tires you will see on the video. But in the instruction I used the closest in case of size official Lego tires. You can of course put bigger tires, like Lego tractor tires: 107mm, but some rubbing during extreme off-roading is possible. Couple words on the truck itself: Star 266 took part in two competitions in 2023, so it is well tested, any minor issues were eliminated and I'm convinced, that it can be used in hard terrain without any worries. It is rather simple construction, to reduce the weight. Details are there mostly to be able to fulfill competitions requirements. The truck is the mix of many ideas I had during designing and I wanted to test during proper, official competitions. Some of them proved to be hard terrain effective, some of them, not. So this is for sure not the ideal trial truck. But it is not afraid of outdoor obstacles, mud, dirt, stones etc. Pros of Star 266: high ground clearance (7 studs with 96mm tires) high approach, break over and departure angles highly response suspension with long travel to fast and precise surface adaptation each axle is connected directly to coupled 2 PF XL motors, which allows to stable, equal speed of all wheels and provides (when needed) all available power for the wheel which needs it the most steering is done with PF L motor for speed and strength, possible steering angles are > 45 degrees per site Cons of Star 266: turntables used in each wheel introduce friction, quite a lot of it, I highly recommend to try to reduced it as much as possible (I advise to use a bit of sanding or lubrication, or both) due to lack of any shock absorption, stability is only on decent level truck's cabin shape and location is not the best in case easy passing the gates during competition, but this is my personal opinion Internals of the MOC, so drivetrain and steering with motor on front axle More photos: https://bricksafe.com/pages/keymaker/trial-truck-star-266
