I have a MS Composite digitial reciever 7ch, and a futuaba TX on channel 17. I moved my rx crystal from a futaba rx to the MS COMPOSITE RX, and it does not work, tried it on both FM and PCM. SO since it doesnt work with a futaba crystal, which crystal will it work with?

I dont want to buy all the crystals till I get one right...I emailed and called MS but they are terrible about getting back to me, and the place I bought it from didnt know and just told me to call MS....so Im back at step one, what crystal works with MS recievers?

ANY HELP PLEASE!!!!!!

THANKS
