thanks for the advice. The retailer is sending out a correct crystal set. I will keep an eye out for any tanks though..  Thanks again guys

I have a H/B fixed pitch with a 35.870mhz crystal. This was in the H/B from new (January). I went to a local indoor meeting and was advised this is an incorrect frequency for aero flying. Should the retailer be selling helicopters with crystals outside the given range? The retailer was Buzzflyer who are very difficult to contact. I am waiting for a reply from them. Thanks for any advise
