You want it to be reversed via radio control while in use, or just a one time reversal to make it a pusher ?

Reversed via RC. In case I encounter any obstacles that I need to back out of.

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

but i was just going to do a simple block with the wires in and out reversed here

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??

you could buy a toggle switch for this but then the servo has the wieght of the spring to throw each time and would be harder to stop the motor in middle of movement

Don, I had thought about making a slider switch to reverse polarity. Thanks for the schematics.

hi mate.
how are you doing with the cruiser?
I did not put the revers switch in mine in the end as it was going to my grandson and so kept it simple for 'dad' to sort out '''''''''''''''' may be''''''''''''''''''''
