After a few month break it's time to get back to Lego and Eurobricks, and why not do it in style
I give you the leopard 4x4:
The model is a combination of the following ideas and concepts:
Quite some time ago I came up with double torque tube suspension idea and now it was time to use it in a real model
Claas tyres were an obvious choice due to their agressive profile and massive size.
With the release of the 42069 set, I was finally able to build a model with a unique and striking color combination
The final model took me some 12 hours to build and the features are as following:
- Powered by 4 RC motors and 2 Buwizz
- Double torque tube suspension
- Independent dual drivelines
- Dual servo steering gemoetry
- Working winch
- Working lights
- Openable doors
- Openable hood
- Openable and removable rear cover
- Width: 24 cm
- Height: 24 cm
- Weight: 1600 grams
- Final gear ratio: 1:5 from outermost RC motor output
- Total power: ~60 watts
Now onto the photos:
The rear trunk can be opened:
There is barely enough room left for seats in the interior. Notice the different springs used to potimise suspension.
The before mentioned springs give the model excellent flex:
There are two servo motors used in order to keep the steering system as stiff and strong as possible:
Under the hood there is a hidden winch, which is strong enough to lift the car:
And the final, most important photo. Notice how the left and right side wheel drive axles use different colored joiners and bushes:
And finally there is a video of the model in action:
Safe to say the combiantion of the four RC motors and two Buwizzes with a low gear combiantion of 1:5 results in a model with impressive performance.
As seen in the video Leopard can wheelspin all 4 wheels when accelerating on flat surface, which is a first for any of my Lego offroaders.
Dual servo motors provide massive steering power and rigidity and allow the wheels to be steered into obstacles with ease.
Only downside to the model is it's slightly high center of gravity cause by all the added panels and detailing.
P.S. It feels good to be back
