Re: Pre modded servo boards for escs?

Hi MySolderIsOlder Not questioning your obviously thorough testing, but this is quite different to the results I have been getting. I received another batch of 10 units recently for "stock", but haven't needed to dip into them yet. You have me wondering now if the Chinese have been "tampering" with ...

Re: Pre modded servo boards for escs?

This is our preferred Rx .. https://www.banggood.com/Flysky-FS2A-4CH-AFHDS-2A-Mini-Compatible-Receiver-PWM-Output-for-Flysky-i6-i6X-i6S-p-1214269.html?rmmds=myorder&cur_warehouse=CN We tend to use the FlySky i6 Tx. Or if you have a 6 volt Rx and a weapon motor, maybe the weapon ESC has a BEC function.

Re: Pre modded servo boards for escs?

No mods needed at all.
There is no potentiometer.
These are really a purpose made small 2 way ESC.

Note that if you run 2S - 8.4 volts and an Rx that can only handle 6 volts, you will need to regulate a power source for the Rx.
I tend to use Rx that is rated to 10 volts, so no problem.

Re: Power connectors identification / naming

3) These are probably a "JST DS LOSI 2.0MM 2 Pin Connector". The plugs have flat pins, exposed on one side.

Re: Another New Antweight..

Just watched GFTGA in action.
Impressive the way it rolls around.
How many servos does it have?
Any close up photos of the construction detail?
If it's not too proprietary ;)

Re: Team Antiquarian build diary

I have used the JST connectors for motors, and cut away the outer plastic shield around the pins on the plug. This "depolarises" (is this a word?) them to allow easily changing motor polarity.

Re: Wheely big Help...

Hmmm. I've never disassembled one (in an orderly way) either. Now I look closely, the gearhead is riveted together, so you may ruin it for future use if you prise it apart. Just undo the 2 screws to remove the motor, and leave it off. The gears should idle around fairly freely. If you are mounting t...

Re: Wheely big Help...

Perhaps try running 3S (3 x 1S in series) on the slower motors, if your ESCs can handle it? Alternatively, you could remove the final gear cluster from an N20 gearbox to make the output shaft into an idler, for a non powered wheel. Without knowing your full setup, these are just ideas to get by in t...

Re: T_Y's Build Log

A tip I figured out, when removing/desoldering multiple header pins ..
Carefully prise the plastic pin holder off first, then desolder and remove the pins individually.

Re: Ant Attempt 2 - 'Tough Justice'

Yes, those are capacitors that come with the DasMikro, in the picture.
The N20 motors don't really seem to need them.
You will have to acquire the resistors separately if you want to use them for braking.

Re: T_Y's Build Log

Well, braking would generally be a good thing, subject to personal driving preference. But on these particular ESCs, which I presume are primarily intended for RC cars, braking means you move the stick up to go forward, then far down to stop with braking, then back to centre, then back down if you w...

Re: T_Y's Build Log

The switch on the end of the pair of wires on the JMT (and the Bustophedon) is simply for on - off. It is redundant in our application, so better to cut it off, shorten the wires, and join them together. The switch on the corner of the Bustophedon board is for the braking function. Keep it off, slid...

Re: Mark's Antweight build

Thanks for that link. It just seems that an Arduino or raspberry pi board has far more functionality than is actually needed to link an RC Rx to an H bridge just to control 2 motors, so costs too much in terms of space and weight. Providing the 5 volt supply is easy enough, but I wonder if the "micr...
