R/C MIXer  FOR DELTA WIND & V-TAIL  V1.0

PIC12C508A  /509A  /16F84A

A  R/C mixer is an electronic device, function as mix two servo signals (PWM) from a radio control receiver to produce the sum and difference signals.

If you want to fly a delta wing like ZAGI, but only have a conventional non-mix radio system, you have to get this.

This  MIXer 508A has only two components, microprocessor & capacitor. Two optional jumpers use to adjust mixing ratio, if you put all jumpers on, the ratio would be 0.5/0.5 and act as a amplitude reducer. Turn off power, before you change the jumper setting.

Program include configuration as:

16F84A : OSC= XT,  WDT= ENABLE,  PWRT= ENABLE ,  CP= BLANK(DISABLE)

12C508A /509A : OSC= IntRC,  WDT= SET,  MCLR= BLANK,  CP= BLANK,
