First if you use a Hitec Rx it must be a positive shift version or one of the shift selectable, autoshift models. I don,t beleve futaba sells anything in Rx's that is selectable.

CHEERS JOHN AM THINKING OF A GWS MAYBEE I THINK THEY AR JR SAFE

No, as a rule most JR receivers are single conversion and most Futaba and the better Hitecs are dual conversion. A single conversion crystal will never work in a dual conversion receiver. Mixing brands of crystals and receivers is never a good idea.
The negative and positive shift issue that John referred to is only on the 72Mhz band that we use in North America, in the UK you do not have to consider that[8D] all brands of PPM/FM receivers will work with any brand of transmitter for you. But using the improper crystal for your receiver is the most common cause of folks asking "why won't my radio give a good range check and it glitches like crazy"
Good luck,

The golden rule is ALWAYS to use the Manufacturers crystal. Never NEVER use a 3rd party's crystal.... it may work or appear to work but invariably it will give you crap range.

Crystals are no longer interchangeable between brands.
Transmitter Crystals - do not interchange between brands except as listed by GWS

What type of crystal do you need ?
