I fly with JR equipment, tx,rx and servos, all on chn 40. What is the deal with trying to find a crystal? Every place I look online and LHS withen 200 miles are sold out of the crystal. I looked on Horizan Hobby today and they said the crystal was out of production. I would have posted this on the JR forum but its closed. Can I buy that spektrum radio modual to my JR 600 radio so I dont have to worry about freqs?
