<DIV><FONT face=Arial size=2>I don't know what their limit is, but I did just
scope the output of a Spektrum R921 and it's a 3.4V pulse on an unloaded
channel. A lot of this can depend on lead length and drive capability of
the channel output, so 3.4V from a R921 or 2.7V from a R6014S becomes something
less at the servo input. I still have an R955, but I can't measure it
since I no longer have a PCM Tx (it's for sale too - cheap!).</FONT></DIV>

<DIV><FONT face=Arial size=2> What do the typical JR servos that we use
in Pattern planes (8411, 9411, etc.) like to see? I want to use them with my
Futaba 5114 (PCM - G3, 72 Mhz) receivers. I'll check the signal levels on the
receivers this weekend.</FONT></DIV>

<DIV>Aside from using a purpose built servo that matches logic families with
the receiver, the only real solution is to insert a level translater in
between; basically a simple buffer that allows you to take a lower voltage
ourput signal from one logic family in the receiver and boost the signal
level to work with a servo that requires higher levels for safe operating
margins. Personally, I would not fly other servos without doing this,
even if they seem to be working fine. Jim Oddino's post
used two very instructive words: "ragged edge". </DIV>

<DIV>I think I read somewhere that the R608FS receiver uses the same
chipset and has the same problem.</DIV>
<DIV> </DIV>
<DIV>So far I have not had any problems with the servos that I use,
but I was not able to check the pulse width out of the
higher channels with my Hitec programmer. I have to wonder, however,
exactly what is the logic level for the various servos? Also, does
the logic level of the servo change with a different battery
voltage? Does the output level from the rx change with a different
battery voltage?</DIV>
<DIV> </DIV>
<DIV>I guess this is a good reason to use some sort of output
conditioner (powerbox, etc) if mixing brands of receivers and
servos.<BR></DIV>

<DIV><FONT face=Arial size=2>I was reading the FAQ section of the
Futaba website when a particular item caught my eye regarding the
R6014FS 2.4 receiver. The FAQ states that <FONT
face="Times New Roman" size=3>the use of non Futaba digital servos
with the R6014FS receiver may be problematic due to the 6014's
lower output voltage of 2.7 volts. Since I do occasionally
mix and match Futaba and JR servos and use the 8 channel 2.4
receiver, I wondered if this issue was common to all Futaba 2.4
receivers. Here's Futaba's answer: "The FAQ refers only to
the R6014FS receiver, this is the only one that has the lower
voltage." Just thought I'd pass this along in case someone
experiences performance anomalies with the 6014 receivers using
other than Futaba servos.</FONT></FONT></DIV>
