thanks for the technical readout on how the tx works. i havnt bought anything from th scratch and dent yet but i need to upgrade my tx. i guess i have to wait a while till i get one on my channel (or just buy one on my ch). im in no rush.
i think why people get confused on this topic is when you change a tx channel to another one it works (not as well but that would be hard to notice if doing a quick test), the crystal on some tx's are removable, and the fact that you can buy tx crystals.
