Motor reversing switch

[David MeierParticipant @davidmeier28154]

I wanted to make a servo operated reversing switch so that I could use the cheaper aeroplane esc’s in my boats.

The disc is made from a piece of single sided printed circuit board, the contacts on the rotor arm are made from phosphor bronze shim. The Tower Pro servo cost $3.79 US and the Turnigy 20 amp brushed ESC cost $4.95 US both were from HobbyKing Online R/C Hobby Store

 

Of course you do need more than a two channel transmitter.

David,

 

Many thanks for a briliant way of reversing small brushless motors. I shall certainly try it. As an aside I have bought quite a number of DSM2 compatible receivers and small servos from HobbyKing.com in the past without any problems at all.

 

Their prices are spectacularly low and anything that helps reduce the cost of our hobby has to be good!

Thanks for your comments John.

I agree that anything that helps to reduce the cost of our hobby is good and on that line of thought here is another site of very reasonable RC bits that I have found very useful for use on boats even though it is mainly focused on RC helicopters.
