For the next Allround Car Competition, the theme is "All But Four", meaning all contestants have to make an RC-vehicule with any number of wheels exept 4. Since building light is a good technique to make a fast car, I chose the minimum number of wheels with which is was possible to make an RC-car: 3.
To give it good driving capabilities, I wanted to include the following:
* Make it as light as possible
* Differential for smooth cornering
* Good steering-lock for good manouvrability
* Return-to-centre steering for comfortable controll
And to give it just a bit extra than just an RC-vehicule, I included a working V4-engine. It also has front & rear-lights.
For the return-to-centre steering, this part was used. It has an internal spring, which returns an axle to neutral position. An M-motor was used. Different gear-setup were tested to find the one with the best steering-lock/Return-to-neutral performance. Te result is a very manouvrable trike.
For propulsion, I chose an XL-motor. It's speed was increased by a factor 2 in a drivetrain comparable to my E.R.T.W.D.. It is quite fast, while still having some power to drive over some obstacles.
Again, I made full building instructions so all you Trike-lovers can build your own. The instructions can be downloaded on my website www.jurgenstechniccorner.com. I made some nice renders from the ML-Cad model:
Awesome! If I had the technic pieces I would download the instructions but unfortunatly I don't. Could you please comment on my VW Beetle Volksrod, it isn't a tenchnic...
