  1. Hi guys! Here's a demonstration model I built to show the potential of Buwizz. There were several goals for this model: Keep it small and light Gearing should be as simple and efficient as possible - ended up using a 40 tooth gear powering the older style differential, getting a 40/:16 gear ratio Advanced steering solution - pivot point is inside the wheel and the car is using ackermann steering geometry for best possible steering and efficiency Use Buwizz as a structural support - not only does the Buwizz power and control the car, it also helds it together Working steering wheel and openable doors - have them too Here's the result: In the gif below you can see the way the car is built and how the steering system works The end result is a very fast and maneuverable car that faces same problems as the big ones. Its actually so fast, that its easy to understeer at high speed or oversteer when accelerating. Controling it at high speed can be very hard, but thanks to Buwiz's different speed modes you can easily slow down the car. This is very usefull for parking or precise maneuvering. To finish up with a bang, here's a video: If there will be enough demand I will create an LDD model of this little speed devil

    [MOC] Logging Truck

    Hello everybody, I present to you another "ancient" MOC of mine - built in May 2016 and only now I finally managed to make a presentation of it - The Logging Truck: At first it was supposed to be a Trial Truck, but as it grew to heavy, especially due to "model team-ish" cabin, I decided to make it more easy going. It doesn't represent any particular model, nor is it scaled or anything... It's driven by a PF XL motor and steered by a PF M motor. It has full suspension, detailed cabin interior and engine compartment. Oh, and I have to admit it is heavilly inspired by Ingmar Spijkhoven's work (2LegoOrNot2Lego). I'll let the photos do the talking... The position of the trailer trolley can be adjusted between the two yellow stops - the main beam slides through the trolley and is held in place by springs and rubber 2L connectors. While the truck is fully suspended, the trailer uses a kind of pendular linkage between both axles. The cabin has detailed interior... ...and so does the engine bay - totaly imaginatory - without any knowledge or research of the real truck engines . I guess under skirt shot is in order... I really like how the front axle turned out, the ackermann is almost to much. Here's another pair of photos to finish it off and a short video of course... I hope you like it and thanks for comment. Please find bigger photos here. Best regards, Miha
  3. I've been trying to build a 1:10, rear-wheel-drive rally car and am running into a number of problems. Right now the issues are with the front suspension and steering. I had hoped to have 1) short long arms suspension (for progressive camber with suspension travel) 2) some caster angle (to help with bump steer) 3) Ackerman steering (or close to it); here I'm using a three-piece tie rod [EDIT: adding a bit of longitudinal reinforcement fixed a lot of this, but I'd still like to hear what people think of the setup and if they have any suggestions] However, I'm having three two problems: 1) SLA suspension plus caster leads to terrible toe-in and -out with suspension travel 2) The tie rods are behind the wheels, and there is way too much play in the system (and some toe-out when moving forward). Some of this I know is due to my not having fully reinforced the steering rack assembly, but I'm not sure more reinforcement will totally fix it. Basically, the two-stud-wide rack assembly wiggles forward and backward a lot when you push on the wheels. 3) With aligned and equal-length wishbones, I get near-Ackerman performance; with this setup I no longer seem to. The wheelbase is 30 studs, and the current (tentative) design is below. Top (with the motor towards the front of the vehicle) Bottom (note that the 6L arms are offset .5 studs from the top arms): Any advice would be much appreciated. Or if you can think of other people's MOCs I should look at for inspiration, let me know. Thank you!
