Fw: switches [TANKS]

["Chrysanthos Kanellopoulos" <xchrysk-at-otenet.gr>]

I already fixed a home made relay on the half moon disc, but the electricity running so close to the servo produces electromagnetic fields that mess with the servo. It swings crazily left and right and it is impossible to control...... Is there something I am not doing right?

 

Frank, thanks for letting me know !

Chris, I am planning to improve the system with more relays.

CHris, the tanks are big, however the jpgs are small.

 

*where have the eu tank.forum disappeared? The US is in the lead, again!!!

That will work.  That's exactly how the Goer is controlled.  One servo 
is used to operate the throttle and the other is used to cut-off on or 
the other motor to turn.

you say no reverse? isn't there some way of toggling a set of relays that would reverse the electric
 current to the motors? when the relays are off, you have your forward, when power is given to the 
relays, you have reverse. I'm sure if you use a servo set up like you where just saying, you could 
have a serve switch set up to reverse the power to the one motor but only when the stick is way 
over (at it'd end) so the reversing servo will only reverse when it is at it's limit also
