  1. Hello EB! I'd like to humbly show this remote control (PF) winter expedition vehicle (MOC). Featuring 4 independently driven tracks with a unique steering system. More explanation below and in my YouTube video. It has many issues that I'm not willing to spend more time to fix, but I've learned a lot from the process, which will help improve my future MOCs. If I was to start from scratch here's what I would change: Put motors closer to driven axles Split drivelines into either front/back or single motor per tread less complicated steering system Use a different type of suspension instead of pendular raise the height of the driven sprocket instead of extending driveline with gears reduce weight with panels vs lifttarms (I didn't have any at the time of building) Never use an Adder again, or if I really have to then use the old-style 24t differentials Work more on the cabin/exterior design A sizeable portion of the issues stemmed from the weight, which is something I didn't expect! I ordered some parts to allow me to finish the frame, and added design elements in the meantime. The design elements were pretty much the difference between being-able-to-carry-its-own-weight and not. The MOC is already disassembled, but I'll be happy to hear feedback and suggestions!
  2. I think it's time to update and rebuild the legend.. Differences between the old and the new model: Because the model will be powered by 3x BuWizz instead of 4 AA battery boxes, it will be at least a kilogam lighter. Independent suspension will be changed to a live axle suspended pendular type. This will allow for much more movement when going offroad and more even weight distribution on the axles. Gear ratio will be changed from 1:3 to 1:1,677 due to the increased power of the motors, decreased weight and improved suspension - making the model 80% faster. NO MORE U JOINTS. Since no U joint, or CV can withstand the torque of an XL motor powered by BuWizz, the motors are now directly mounted on the hubs and steer with the wheels. Because there are no U joints the axle can be narrower by 4 studs, but I had to sacrifice a stud of ground clearance comapared to the old one. Servo steering - steering is now updated with 2 servo motors, each in their own axle. Front-most axle's steering angle is 25 degrees. Rear axles no longer need steering due to... Differential steering - since all motors can be individually controlled, the BuWizz's app allows for automatic correction of motor speeds when steering. This means the model can steer even tighter by reducing the speed of the inner motors when steering. Improved wheel mounting points using parts 24122 - the torque is now sent directly to the inside of the wheels without having to use 24 tooth gears and pins. I ordered the missing components and will send photos of the build as it progresses. For the bodywork I am thinking about a red cabine, but not sure which style - high and flat, or low which stick out in front further. Additional functions will be a winch in the front and possibly a crane arm in the back - I will decide on that after I see how it performs.
