A RC servo needs a 150ms pulse,


** Wrong - it's 1.5 mS.

I stand corrected, amazing how fast one forgets things one programmed

so long ago...


** Those familiar with RC gear know there is a pulse stream sent by the
transmitter with a repetition rate of about 40 / 50 Hz. The number of
pulses sent is one more than the number of channels and can be as high as
10 - which must fit into a 20 to 25 mS long frame.

The rest is history - as they say.



Yes, in remote controlled toys et.


** You have missed my point - which was about how most folk manage to
recall specific tech details.

Those who take up a RC hobby rarely buy individual RC servos, as you did,
cos that would be of no use to them.

BTW:

Never allude to a fully functioning RC airplanes, racing cars or racing
boats as "toys".

Cos they fucking ain't.

I always remeber that scene in "The Flight of the Phoenix" when Hardy
Kruger lost his cool, when they called his model plane designs "toys"
