Sergio Zigras' F1Q timer

This timer is available from Bob Selman at BSD Micro RC as the ZTRON FF Timer for $US 30.00 plus P&P. Look under Misc. Electronics to order it or download a manual in PDF format. Features:

• controls brushed or brushless motors via an ESC
• powered by the ESC's BEC function so must use a BEC equipped ESC
• uses a servo to release the d/t but has no capability to operate AR or VIT
• weighs 2 grams
• programmed by a row of onboard DIP switches and the start button.
• The motor run is settable in 1 second steps from 1 to 63 seconds.
• The d/t is settable in 15 second steps from 15 seconds to 15 minutes.
• The motor is throttleable in 63 steps from off to full on.
• Uses soft-start and soft-stop for the motor to save gear wear.
• Requires a momentary push followed by a push-and-hold on the start button to start the motor. The timers then both start when the button is released as the model is launched. After d/t the timer must be powered off and on before the motor can be restarted: this meets the F1Q lockout requirement.

The timer's main limitation is its inability to control VIT and auto-rudder functions. This may be a hardware limitation: the timer appears to be ZTRON CL hardware with a new program to adapt it for F1Q.

You can find a copy of the original manual here, though I don't guarantee it is up to date. You can find out anything that isn't covered here or on the BSD Micro RC website by contacting Sergio Zigras direct.
