Default Hitec 27 band crystal question

Hi I have a Hitec Lynx 3D radio that i had a spektrum in.. I got a new CRX and am using the spektrum for that. I have the stock 27 band module, and a reciever. I have been looking for a crystal set for the radio. All i can find is am/fm offbrand crystals. They say they work for am and fm. I dont want to get a bad set that doesnt work. i have a few questions.


The module is # HP-MIC.
The reciever is the HFS-03MM 3 Channel.

1st. Will this module and reciever combo work together with the proper crystals?
2nd. Will the crystals listed to work with both AM and FM work properly with the FM setup above.

Thanks in advance..

Use only FM x'tals.

If you use Hitec x'tals, make sure and get Single conversion x'tals for the Rx.

Transmitter crystals are either AM or FM. Receiver crystals are either AM/Single Conversion FM or Dual Conversion FM. Any receiver crystal marked AM is AOK in a Single Conversion FM receiver and vice versa. Refer to
Data - What type of crystal do you need
Much more under sub section
"Radio Systems, Accessories, Alterations and FAQ" on my web page.

(xx is the channel number you want. 01-06 for 27 mhz)
