The 'Tamiya' servo

So, I wanted really long legs on a hex, and people claimed that normal servo’s wouldn’t be strong enough… maybe not even those big 300oz/in ones.

So, what does a girl do to build her super hex?

Look at alternative solutions! Because Jim’s super gearbox servo things aren’t here yet, I am experimenting on my own.

Today, was a Tamiya worm gear box. These have 4mm shafts, and I was wondering if they would work well with LM’s 4mm hubs and the SES.

Now, I did gut a cheap GWS servo I had lying around for the control circuit. I hooked it all up, it was looking very hacked on that big motor :stuck_out_tongue: However, when I plugged it in to a RC receiver, and turned it on, the GWS controller decided to drive the motor until the C bracket slapped the motor. (All despite the fact that the pot was centered.) This of course resulted in the fabulous magic smoke as the GWS controller board gave up its life. So, I ripped that all off. (next time, don’t lock the set screws before testing, and take a picture before blowing things up!!)

Anyone have any recommendations now for a good way to ‘servoize’ this motor?

Thanks,
Caitlyn

You’ll just need to work out a way to mechanically link the feedback pot to the output shaft of your gearbox, and wire that back to some servo guts that are capable of driving your motor under load without letting out the magic blue smoke.

So long as the board is capable of driving your motor, and the feedback pot isn’t hooked up backwards (heh), a servo doesn’t care what it looks like - so far as it knows, it’s just a servo.
