Somthing for electric RC car guys

At the moment my idea is to make a car that can ride a mono rail, that is pretty much just a board.
A motor should the drive on 1 of the wheels and the wheels on one side should be spring loaded so they always "clamp" down on the board to provide tension.
There should then be a switch in either end the car hit, and that then flip the DV voltage so the car go the other way, by varying the voltage you can change the speed, though i do think at 50 M we plan to set up on, the speed should not exceed a brisk walking pace.

The motor / electronics should be on the back side of the mono rail protected by a steel plate, the hand over of power from the mono rail should be at the top of the rail / board so the "car" always press down on the connectors,,,,,,, connectors you like garden railway where you use track power probably need to clean,,,,, but this should only take a few minutes for a 20 - 30 feet long rail.

These power rails could be pieces of metal into a grove in the wood, it could probably also just be clean copper wire in a even shallower groove.
Just like building a routed wood slot car track. Rheostat could control voltage and easy enough to put in a polarity reversing switch to change direction. But how are you going to operate the switches from 50 M away? That’s a lot of wire. And those metal rails outside will take frequent cleaning to maintain conductivity.
 
I think you just turn it on after you have put in a clean target paper.
Yes the brass track of our G scale railway did take some cleaning in the old days when we used track power ( 18 volts ) , now we have changed to battery power instead.

You can get a track cleaning pad, that work pretty okay and fast too, or if you want to a track cleaning train too.
But a block like that on a stick so we dont have to bend over, should only take a few minutes to remove oxidation since last session.

Alternative a sanding thing in a battery drill and you are also soon off to the races.

Using a battery on the "car" here might also be possible, it will not be a power hog, so a 3000 MAH battery will probably last a long time.
 
This looks fun. I got 1/8th scale nitro buggies , but if i had a cheap electric rc body and a living friend to swap driving/ shooting at it would be a blast (till you blasted the car its mounted on ..lol) .
Maybe add at min 3/16 steel side plates for tire/ frame armor?

Now why didn't i think of it?😜
