Is it possible to replace a 40Mhz crystal with a 49.860Mhz?
I bought a RC submarine that was running at 40Mhz. Submarine broke, seller shipped a replacement, but replacement could not be remotely controlled by original remote. In fact, while looking under the submarine, there was a sticker written "49Mhz - 3". I guess it is referring to Channel 3 - 49.860Mhz. So could I buy a 49.860 crystal, remove the 40Mhz crystal from remote controller, and get my submarine to run again? Is there anything else to consider???
