this is what my work order said once I got my radio back from Hitec after I had sent it in for glitching problems. Kind of ridiculous if you ask me. How does the Spectra module fall out of tune? Its not like the transmitter is being shaken around in my hands or gets knocked around... why would this component just decide to break? How often should I expect something like this to happen? When I sent in my radio for this problem I asked these same questions but received no answers. It was very upseting that this randomly happened to me since It completely ruined my time at the Kyosho Challenge this summer. I only get a chance to go to one big race a year (if that) and the last thing I expect to give me problems is my transmitter. Especially one that isn't even a year old. I hope someone from Hitec can answer my question here since right now I am stuck between a rock and a hard place. I REALLY do not want to give up my CRX. It is by far and away the most comfortable radio I have ever used and easy to set up, but I prefer something that works over something that doesn't. I don't want to wait for the next time this radio falls "out of tune" during another important event. I know for sure I am done with synthesized operation. The out of tune spectra coupled with Novak's garbage XXtra receiver (3 of these have gone bad on me) is a bad combination..... I was thinking of just replacing all my XXtras with the DCX receiver, but this of course doesn't assure me that the Spectra wont continue giving me problems. Should I keep the Spectra and CRX? Was this problem very uncommon? Or should I change the transmitter as well over to crystal control.... can the crystal module fall out of tune as well?
Lastly, if I do decide to change transmitters, does the HFS-03MM work with Futaba's new 3PM transmitter?

I've been using the Futaba 3PJS with Spectra and Novak Xxtra receiver for quite some time and it has never gone bad on me. Only time was the antenna got cut inside the Xxtra to cause bad reception.

It's electronics. Values of electronics can change for several reasons..

Mostly due to heat.

But, it hard to say. I have never heard of other users having this same issue with the spectra.

I have had my Spectra module for over 4 years with no issues....
I have been running the Xxtra rx's since they came out also...

However, I do like the DCX & HIS-03MK Rx's better.

I have been using my Spectra for about 3 years, no problems at all. I use all DCX receivers. You could get a crystal module to have as a backup if you don't trust it. Or better yet I'll trade you a crystal module with crystals for your spectra! My son could use one.
