Zerobricks Posted February 9 Posted February 9 This model is a result of the lessons I learned while building a mini racer and failing. You can find more details about that here: To create a better mini racer, I increased the scale from 1:16 to 1:12 which allowed me to implement the following functions and features: Independent left/right side All Wheel drive Independent suspension on all wheels Dual 2-speed gearbox Steeering angle of around 30 degrees Working steering wheel Full interior with 2 seats Opening doors and bonnet Built out of 999 pieces Measures 35 x 16 x 10 cm Weight of 1 kg For color, I had the choice between orange and lime, so I went with lime for that Lamborghini look with gold rims: And here's the LDD version in all of it's 999 parts: Here are more photos of the individual groups, starting with main driveline: Gearbox switching system actuated by a PU L motor: Steering and rear hub support system: And finally the suspension system which also provides support for the bevel gears: The driveline is the most important part of the model and it uses two 2-speed gearboxes, each driven by both outputs of the BuWizz motors. A PU M motor switches the gears using the wave selectors. Suspension is supported by 8 hard shock absorbers. The suspension is at quite a high angle of around 25 degrees in order to keep the drive motors, steering motor and BuWizz as low as possible. High suspension angle also pulls the wheels together, allowing for a narrower bodywork. A PU L motor provides some 30 degrees of steering angle to the front wheels and also steers the steering wheel via a secondary steering rack. Everything is powered and controlled by a BuWizz 3.0 hidden in the front. Here's how everything looks like inside the model: More details and video of the model in action can be found in the video: To finish, I'm really happy both with performance and the looks of the model. It for sure fixed and improved mostm if not all the issues with the previous, smaller version. I also can't wait to compete with when the next opportunity shows up. Quote
Jurss Posted February 10 Posted February 10 Visually there is really some kind of vibe from those old nitro racers. It is tehcnical, not so pilished as some copy of real car. Technical side also is interesting. Quote
