RD620 Dual Conv. Receiver

[kit]

What crystal does the dual conversion RD620 Rx use and where do we get them?

Do you sell them? (72mhz)

[CSO#1 @UHobbies]

Right now they are all 72mhz
We will have dual conversion crystals for them within 5 days.

So I was wondering where the crystals were? I've got five 820 receivers on backorder and would like to pick up the crystals as well.

Thanks,
Dave

I have 2 rx Corona 620 on 35 Mhz. On the first I use Hitec dual conversion crystal and on the second Webra dual conversion crystal.
No problems.
PS. the webra crystal don't work on electron6 rx.

I have a 35 MHz DS Corona. I tried it with an original Multiplex DS crystal, but it did not work.

I used the same and complete setup (of LiPo battery-ESC-crystal-servo-MPX Cockpit SX with synthesiser module) on a MPX-DS receiver to check these components, and this worked out OK.

GMO78 claims that a Hitec DS crystal is working with this receiver. MPX and Hitec components are essentially the same, as far as I understand. So I would expect that a MPX-DS crystal would do the job as well, or am I wrong in my assumption?

So, will the Corona just not work on a Multiplex DS crystal, or is the Corona faulty? Any suggestions from your experiences and/or expertise?

Thanks!

I would say it depends on the vintage. But then again they may not be compatable at all.

I mean Hitec and MPX

This is straight from Corona:

"The best choice of the crystal will be Futaba’s.
Our receivers are compatible with Futaba and GWS’s crystal. As for HITEC or JR, sorry we haven’t made a rigorous test on them.
Corona has crystal of 72MHz and 36MHz now and 36HMz will be available soon."

I'll be waiting till UH have the corona xtals before buy any of these.

Don't keep us waiting too long UH.

Thanks for your replies, Eagleburger & Kentucky!

From your comments, it seems plausible that I will have to purchage either Futaba, GWS or Corona crystals!

Update:
I ordered and received a DS Futaba crystal from my LHS.
Everything is working perfect now; I am going to order more of these nice Corona-Rx's!
