Hi all,
I am pretty new to the great world of RC construction vehicles of all sorts, I do have some RC experience from helicopters and airplanes but that was some time ago and now I will go back into the RC hobby but staying on the ground. Actually, my little boy loves RC vehicles and already has some Bruder Toys so what would be more obvious than converting one of them to RC.
Luckily I have some tools available and I have a little experience with CAD that was all I needed to start.
Here and in some other places I found some great examples how to attack such a task and I started by drawing the front axle in CAD. The pieces appearing kinda rough and bulky but for my first project I am going to focus on "get it done" and later I will probably go more into detail.
So here you can see the front axis how it shows up in CAD and I already printed some parts to see how they would fit the tire and finally the car. As I mentioned a little bulky but for now I will go with that if it fits into the car and the wheelhouse.
The Bruder model which I chose is the MAN TGS Construction Dump Truck with two drive wheels on either site in the rear.
Since making my own gearbox is currently a little bit too complicated I will use four motors, one for each wheel like shown in many conversion threads before.
I am going to use geared bs motors for that but here I would need some information. The most common ones I can find on Amazon (which might not be the best place) are pretty bulky with a diameter of almost 1.4".
In addition, I am not so sure what motor controller to use, it is a brushed motor and I would like to run 4 motors, is that possible with the same controller or do I need four controllers?
more to come
Thanks
Chris
