Re: Team Antiquarian new build diary

Re the silicone tubing tyres .. Very nice. It would be interesting to try making them say 4 or 5 mm wide. Many people think that more surface area is better, but basic physics states that total friction between two smooth surfaces with a given downforce does not vary with area. They see the benefit ...

Re: Tiny 6mm gear motors appearing in Aliexpress

We have had one Ant run here with them, with 14mm wheels. A 4WD vertical spinner. It drove very well. He was running on 2S with the faster ratio planetary. The problem was wheels breaking off from impacts, though maybe the motors/brushes would have failed if the wheels had lasted longer. I have boug...

Re: Pre modded servo boards for escs?

Hi Stuart

I will be very interested to see how these new Feetech servo ESCs work out?

Mike.

Re: Pre modded servo boards for escs?

I am back home now, and have had a chance to test some of the Doman 360 servos and ESCs .. First I tested the 10 most recent ones (Ordered 17 Mar, Rcd 28 Mar) I ran each one from Ch 1 of an FS-iA6 Rx with 4.92 volts in, and an FS-i6 Tx. They all seem to do "what it says on the packet". Next I ran th...

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.
