REFLECTOR: Elevator trim

[Laurence Coen]

Brett,

The circuit you are showing is different from the one I posted.  Yours works best for those that want to add braking to their existing pitch trim.  The circuit I used has some advantages for those starting from scratch.

1) The relays switch the motor current instead of the switch in the stick.  Improved durability.

2) Only 3 wires to the switch instead of 4.

3) Current for the relay is much smaller than the motor allowing the use of smaller gage wire.

4) No 12v hot wire to the stick.

This is now also on the Wiki, with the original VV image quality.  Also note that the Velocity Views table of contents are fully searchable in the downloads section, so for instance if you searched for "dynamic brake" you could immediately find any article with that text string {see below}.
