Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, 3D designer and modeler.
I have over 15 years experience designing and prototyping different devices and systems across multiple industries.
I would like to collaborate with you on this project and possible future ones.
I could design your remote car, including the extras (door opening, speare wheel dettaching, lights, tail stops, etc) using the same controller as for a drone.
First at all you should clarify the model scale, how the car will be driven - electrical motor or combustion engine, the autonomy and different other things.
The project if you want a quality outcome is not easy, but duable.
It is also important to know how you intend to produce this toy - 3d printing or directely in the mass production.
You may open a chat room here, and we'll discuss all the details.
Regards
Bogdan
