RE: ever here of crystals going bad?
alright so these cars can really take you back to school. So I take apart 3 different receivers today. I'm swapping crystals, checking wires just trying to figure out what I'm doing wrong and then I read the little sticker on the crystal I'm trying to get to work "TX" ......UGH! What a dumbass! I had no idea the package of crystals I purchased previously was a set of RX and TX. I just luckily put the RX in the receiver I was adding at the time and it worked. I thought the package was just a pack of two same frequency crystals. You learn something all the time playing with these things.
