Tx Rx Crystals

I've heard about 'center dot' crystals and surmised that it has something to
do with the accuracy of the frequency.

Last Sunday I got a couple of lock outs (first ones with this heli) and the
board had pins on either side of my channel (49) which is very unusual.

I have noticed that the crystal in my Rx is 'left dot' and in the Tx 'right
dot'. Is this something to be concerned with?

you should be within 1 position with regards to the dots on the Rx and Tx
crystals. (so try to use a center dot position crystal in your Tx and you
can't go wrong.
