Re: servo boards as motor controllers.
would i need to centre the pot before i solder resistors on?

Re: servo boards as motor controllers.
im actualy using some big 40g servo servo boards which i know will take the voltage. the 9g boards will only take up to 6v.
danny, you take the pot off if you are using resistors

Re: servo boards as motor controllers.
I am using,at the moment...
2s lipo,directly connected to servo boards from these servos...

And run through a regulator to the rx.

Re: servo boards as motor controllers.
Harry, how many IC's has your servo board got on it?
If it has two then one will be the H bridge IC and some of them can easily take 15v+. If you're lucky the single ic servos might have two voltage inputs on the chip with one for logic and one for motor power.

ohhh i thought the pot was to programme it then i take it off and put in resistors to keep it there

thanks jim
jordan, i think you are crediting me with more inteligance than i have, can you go simpler?

Re: servo boards as motor controllers.
How are they holding up on 7.4v? when I used them they got a bit warm, so I wimped out and used a 6v regulator. I'm planning on using them in a flea, so it'd be nice to know they can survive 7.4v.earthwormjim wrote:I am using,at the moment...

Re: servo boards as motor controllers.
So far so good.
I have chased the cat round the lounge for a good five minutes at a time on a little test bed chassis,with no probs,must have run 5 or 6 charges through them so far.(insert cute smiley emoticon holding up crossed fingers here.)

Re: servo boards as motor controllers.
If you look at the servo board there will be at least one probably black chip with many legs. Some servos use two chips, one to decode the rc signal and one to drive the motor. The motor driver one can typically take 15V and above so you don't melt the board.haz wrote:thanks jim
