Servos

Hi Mike, There is nothing much to add to what I said. However the connector is not even an old type RC connector.

I have been using RC since the 1960s and familiar with all of the connectors in use then and later.

This 5 gram servo is a Hitec HS 50, I have others with a standard RC plug.

Hi Roy,
Would you have some photos?
These servos are certainly original ones from the 1970s . . .

Servos

Hi all I am looking for info on other applications of servos.
I bought some servos in a box. One of them is a 5 gram servo with 5 wires coming out to an in-line plug.
From one end the colours are, blue, red, white, black, mauve.
It appears to be glued together with no assembly screws, so unable to investigate innards.

Just wondering if there are no electronics inside and perhaps meant for Arduino or the like.

I would like to use it but seek advice first.

Servos

I, like many others, use standard size servos. But they are sometimes too large for the job.

I also use the 9 gram servos, generally with just 0.5 kgrams per cm torque available. This is OK as a rudder servo for about 10 Watts motor power.
I have even smaller ones at 5 grams!

Recently, while trying to find a suitable servo to tuck away for the rudder in a small yacht, I came across 17 gram servos and bought 3 of them.

They were just the size I wanted with a 1.8 kgrm per cm torque. Worked out at about £4 each, including delivery.

I have tested them with old RC (27Mhtz) and they perform well, no chatter when running with motor and esc. (some of my 9 gram servos are very bad)

Dimensions;- 28mm across X 13mm wide and 30mm high + lugs which stick out a bit further.

Regards
Roy
