Earl,<br>
Your numbers imply that the frame rate of the 7008SB is 1/2 the
frame rate of the 6008HS for discrete channels. That doesn't seem
like the right direction for Futaba to be steering. Or is just that
on a SB system the discrete channels are an afterthought?<br>

a high impedance meter with a scope mode. It displays a
voltage at the top of the scope screen, as well as a freq.
Without thinking, that voltage is the number I reported, and
it's 50% different between the RX's because one was operating
at 2X the freq of the other, but it's not pulse amplitude but
average volts. </font></div>

<div><font face="Arial">I took another look and the actual pulse

Pretty obvious upon thinking about it. So - Futaba didn't
change anything and Robert's problem isn't with pulse
amplitude. </font></div>

Earl, something doesn't look right. How did you measure the
pulse amplitude? Did you have a servo connected? I measure 3.0
volts peak unloaded on a 6108SB.

you give Futaba service / Steve Kaluf a
call. It may be that the RX pulse rise is a
little low for the ESC. Futaba have, in the
past at least, used a lower pulse amplitude
than some others which resulted in strange
results when mixing servos on occasion. If
this is the case, the problem is more
compatibility with the ESC than RX defect,
still annoying though.</span></font><o:p></o:p></p>
