Subject: [alt-beam] Fttaba servo as motor/gearbox combo.
content-transfer-encoding: quoted-printable
Hi,
Maybe this subject is old news? I've been thinking about doing a Chiu style=
walker, but have not found similar gear box motors. I now plan to use thre=
e old Futaba servos, as I discovered how to modify them.
If anyone is interested in the process please let me know. I could write up=
the conversion and forward it.
The main point is that they are reversable DC motors and not stepper motors=
. Perhaps I'm the last one on earth to discover this ;-)
