no Reg? if so that is enough to void the warranty.

Thomas, with a123 cells you don't need a reg. Two lipos, possibly, but not a123 cells?

And that is because a freshly charged 5s nicad or nimh pak has a voltage of close to 7 volts. No regulator is required or needed for these packs. The nominal voltage for a 123 pack is 6.6 volts. You tell me what is the difference and why should it matter? I charge my a123 packs the night before. The next day when I fly the packs are at their nominal voltage.

"...and the beatings will continue, until morale improves"

OK, lets demand Futaba to make a complete recall of anything
that ever failed for any reason, then order their CEO before congress...

Then let's run shifts to post complains in this thread every day,
until the end of days.. That mudslinging shift can be shared with
posting to another thread, where the posters would praise vendor X
with posts like " my received was sucked into bull's a..hole,
and it was totally screwed up - many thanks to the great service
of my beloved vendor X who sent me a brand new receiver, together
with a pack of Kleenex and a deospray can, to clean up that mess"

(OK, bring it on...)

The point is that that rx is only rated by the manufacture for 4.8 volt ( 4 cells) "Edit added" to 6.0v (cell) "Edit added" . I know a lot of people are running higher voltage with out mishap but it may just catch up with them someday just as it did you. This attitude from Hobby services you are complaining about was probably (just a guess here) after you got pi$$y with the guy after you found out they wouldnt replace it for free. I commend you for being honest at least with them and here.But the point is you used it outside of spec and that will void the warranty with ANY company. I guess it wasnt a day to go with your namesake.I just think it is unfair that you raise a complaint here considering the situation. Im not trying to bash you here ,just trying to speak the truth to this situation.

No, the rx is not rated at 4.8v. If that was the case, then the futaba servos that are rated at 6.0v are worthless.

I have had good luck with them, but I have also had bad luck with them. It's not about dragging the CEO befor a lynch mob. No, it's about holding them to a standard to serve their customers they way they should be served. Without us buying their products, they would not have a job.

I have called them up before and just tried to get a simple part no. and had them get very fustrated just because I asked them to look up a part no. I have also had them answer the phone and obtain great service.

I disagree with the notion that I'm operating them out of specs.
Again a fully charged 5s nicad or nmh pack is not 6 volts it is 6.9 volts plus tapering to a nominal 6 volts with use. I can only hope that the designers of these receivers took this into account when they were designed. Indeed Futaba should word there specs to say 4.8 to 6 nominal. If these receivers were designed with with a sharp operating cutoff at 6.0 volts and exceeding that threshold would lead to catastrophic failure then that IMHO qualifies them as a poor design. Again Futaba is without actually saying it endorsing 6 volt + operation of these receivers by stating that it is ok to operate them on 5s nmh or nicad packs. At the end of the day it becomes a gotcha that Futaba/Hobby services can use against you to deny warranty coverage. Futaba/Hobby services can get on here and say whatever they want regarding this issue but the evidence will lead to only one conculsion, and that is this receiver would have also failed on a 5s nmh or nicad pack!

I stand corrected as far as the voltage. Here is the tech note spec from the site
SPECS: Size: 1.8 x .9 x .5" (45 x 22 x 12.7mm)
Power Requirement: 4.8 - 6V
A 4 cell rx pack has been the standard for the 30+ years i have been in the hobby. A 5 cell nicad or nimh is a 6v battery the A123 is a 6.6V battery. The point is that you are out of spec by a fair margin on a charged pack. You can easily put an expander( like this- http://www.smart-fly.com/Products/Expander/expander.htm ) on and run whatever you want on the servos but leave the rx reged to the correct voltage it is built for.

This also from the site
All Futaba systems are designed to operate on either 4.8 volts (NiCD 4 cells) or 6 volts (Alkaline 4 cells OR NiCD 5 cells), except certain servos which are specifically labeled for use at one voltage or the other only. Some manufacturer's systems are not designed for and do not operate well on 6 volt, but most Futaba equipment handles the increased power input and provides increased performance, speed and torque.
Im just saying you are running 6.6V+ (around 7.4 at peak charge)at your own risk

Replacing the antenna on the futaba 9Z...
/
/

Ok.. It was easy the get a brand new antenna replacement for my Futaba 9Z WCII.

So, We opened the transmitter... opps... bunch of flat cables, boards, screws...

It was painful... I couldn´t get the old antenna out of transmiter...
There is something I don´t take into account...

Some of you took some pictures when replacing the 9Z antenna?

Where is "the trick" to pull out the antenna from the 9Z?

/
Saludos cordiales,
