Important Info:
For Futaba systems, use only single conversion crystals that match your 75MHz transmitter (JR crystals work fine). Do not reverse polarity of the power source. Any channel can be used as battery input. Do not use outside the voltage range. Do not short input/output pins or pc board. Do not coil antenna (reception loss occurs). Trimming the antenna reduces range. Use a Deans base loaded antenna for best results.
