Switch for Reverse
Hey guys,
Doing a project at school for an RC vehicle that must cover terrain, tight corners etc. To achieve this, i would like to implement reverse, but the vehicle must retain an aircraft brushless setup. I would like to know, if anyone has any ideas on how this vehicle could use a switch REMOTELY to possibly change 2 wires and put the motor in reverse. The solution must be cheap. We are given 1 micro servo, but if anything else is required im sure i can come up with something.
Cheers

Sounds like you aren't drawing a ton of amperage, so there may be some easy options.
The two that come to mind are:
-Double pole double throw switch (DPDT), connected to a servo & on a 3rd channel.
-The other would be a double pole double throw relay & use something as the controller such as an old servos motor output or other wise.
RadioShack switches that should work are:
Catalog #: 275-652
Catalog #: 275-636
Catalog #: 275-663
Drill a hole through the switch lever add a linkage some collars & possibly some pen springs.
The wiring will look odd, but the motor or ESC can go to the "common" on the switch, & the other will go on the outside poles with a crossed jumper to the other set of poles.
If you are only allowed one servo total, The switch can be controlled by steering too far to the left or right, but it might be tricky to drive.
