Idea on different guide wire set-up allowing cars to skid
Posted: Thu 1. Oct 2015 13:18
First of all, apologies for this long first post. I don't have Magracing. I purchased Kickstarter Real FX as I thought it would be a better system, but I'm disappointed with it.
I personally am looking for:
- a system that provides a greater amount of freedom for the cars. To me the car should take a corner line dictated by what the tires can do given track surface and speed.
- preferably a larger scale (1:27), with proportional steering (servo).
One thing I've learned though, the guide wire is the only system that works so far, and can be home build.
The idea: Wires in V's, like >>>>>>>>>, centered on the racing line. There is no continuous wire, the magnet "jumps" from wire to wire as the car moves forward ,and the steering electromagnets would be able to influence the steering in between the V's everywhere on the track. The steering angle becomes a mix of forces the track wires, and forces the electromagnetic input exercise on the steering system. Thus in principal, it should steer by handheld controller input more at low speed, and less at high speed, as the more wires pass per second the less the influence of the electromagnet is.
It would require lots of guide wiring, like 10mm maximum between the V's in turns, and likely additional wiring between the V's on outside of turns. Cars would likely not require modifications.
I believe it would result in:
- all cars follow in principle the racing line, they get guided to the "points" of the V's
- if they go too fast into a corner they can run wide and auto steer back to the line.
- steering anywhere on the track
- system requires less force/distance between wire and magnet, the car should "leave" the wires fairly easily. This would also allow the "track cover" system, a solid plate covering all wires.
- if it works the game would be to play with speed, and use steering to set up the car for another line thru the corner to pass
I've done a simple test with a 10x3mm magnet (from a name plate) on top of a 5mm thick glass plate, and it follows the wire underneath. Whether it still has the force to turn the wheels is a question
I think the angle of V would be a compromise between how fast it auto steers (narrow V), and how fast it steers manually (wide V), so 90 degrees, 45 each side, seems the middle way.
To only test it:
I think the best & easiest is to build a small circular track, 40 cm or so diameter for the "racing line". Cut the V grooves for the wires, and drill a hole on the point of the V to be able to put the 90 degree bend in the wire in (drilling the holes first is easier). Cover it with something solid up to 2?mm. DIY store has cheap 2mm wooden plates, plexiglass etc.
If it works, at low speeds you should be able to steer to the inside of the 40cm diameter "ideal line", as well as to the outside. And with increasing speed the car should start to run at a greater than 40 cm diameter line, and come back when you decrease speed. But at 40 cm diameter your looking at qty 125 V's spaced at 10 mm
The major question I think is if 10mm spacing between V's is enough. Maybe it needs to be 5mm..
Anyways, I thought the concept is valid and wanted to share it.
