hi VC
I will be 'making' a reverse currant switch.......4ch tx?..................hahaha same as me............. use a servo to trigger the reverse.
one idea here
http://website.lineone.net/~alanann/hints.htmbut i was just going to do a simple block with the wires in and out reversed here
Scratch build - Antares Cabin Cruiser
the servo at bottom right slides a plate with two wires from the esc.
the wires from the motor go to the back of block (2 red off red terminal ) the wires from esc go on the slider block ,
then a slow tx contorl on the servo stops the motor then reverses it as the stick is moved whichever way for the servo.and the slider moves from one set of contacts to the other.
so the polarity goes....right to left ...from red /black to black/red so when slider moved it would then be red esc wire to black motor wire instead of red.
on a brushless motor this should be ok for the short periods of reverse use.
easy?
?
