I have a JR 652 radio system on channel 16. My Blade CP is on channel 52. If I use the JR channel 16 crystal rx crystal in the blade 4-1 will that work or is the channel spacing too far apart? Thanks.

The Blade Rx is negative shift. The JR Tx is positive shift. The Rx will not respond to the Tx because of the shift difference regardless of any crystal swapping

The Hitec should work. HiTec and Futaba are compatible shift.

Your Hitec should be fine as it is negative shift.

Do I need a special crystal? Is the blade single conversion?

You only need a crsytal in your 4-in-1 that matches your frequency.

Your Tx does NOT need special crystal.

For the 4-in-1, use a single conversion Futaba 'Short' crystal - don't ask me why they call it short, it looks the same.

stealth,

I have often wondered about that myself. I have both types of Futaba Rx's and the crystals seem to be the same length. The double conversion have red and white labels and the single black and white.
