screw adjustment on ESC?

[James Rolfe \(Agg - OCAU\)]

What's it do, then? :) I don't know the brand/model of ESC, no markings on
it. It's a grey body with a purple heatsink, if that means anything. Given
up on the guy who sold me the cars ever sending me the manuals. It's on an
original RC10 and has 1 green and 1 red LED. There's a small pushbuttony
thing and a philips-head adjuster, any ideas what these do? The reason I
ask is, the ESC turns the car off when the battery is low - but at the
moment it seems to do it well before time, when there's still a fair bit of
charge left in the car. I'm hoping that screw thing is a sensitivity
adjustment.. maybe I should just fiddle with it and see.

On many esc's the screw is either a brake, power, or both, adjuster.
You would need to experiment to see what this does. I'd say screw it in
fully (generally only 1 full turn either way) then with the car setup as
below, and on a wide open area, nail the throttle for a second then full
brake. Screw the adjuster fully the opposite way and nail the throttle
for a second, and then full brake. Compare the differences in the
'attitude' of the car to see what (if any) efects the screw has.

The push-button is possibly a set-up button.

Generally, turn radio set on, turn batteries on while holding the
button. When button is released another press and release sets
'neutral', move the throttle stick to full and press and release the
button, then move the throttle stick to full brake/reverse and press and
release the button. This is a method of setting the esc to match the
transmitter. There are variations on this, some set neutral at the
first press and only need two more presses to set forwards and brake,
for instance.

its more likely to be what paul said as to what it would be but i've seen
some escs have the screw adjustment as the neutral set.

Yeah, Tekins used to do that, but then they had two, or more, adjustable
buttons, for top end, and for neutral .. ;)
