needed. One by one, move your controls and carefully watch to see if
it looks like the any of them are straining at the end of their maximum
travel. Check the throttle in particular. I have seen digital
servo cases melt from having the throw set up further than the linkage will
allow. If that's not it, disconnect the linkages at servo and work
the control surface by hand. If it does not move very freely, fix it.
If you don't find the problem there, work the servos around in a 10 minute
mock flight on the ground, except exaggerate the movements considerably
since there will be no air load and engine vibration to add to the
load. Listen to each servo. If it sounds like it's having a
problem, remove it and check it out on the bench. If there's nothing
obviously wrong by the sound of things, then feel the servo cases to
see if any of them are getting warm, or even try smelling them for that
characteristic smell that hot electronics tend to have. If there is a
regulator that got so hot as to discolor it, and there is nothing at all
wrong with the linkages or control surfaces, then this ought to find the
culprit.<br>

You will need a very good meter to read the current, because a fully loaded
digital setup takes the current in short spikes and most meters do not have
a good enough frequency response. I have tried using a very good quality HP
meter with over 20k frequency response and concluded it's not accurate, but
it does give you a ball park number and will indicate if you have a serious
problem. I have monitored my receiver voltage using a FDR data recorder and
using two nimh batteries pack in parallel see at least one volt drop spikes
at the receiver when the servos are heavily loaded. I run 2
20amp schottky diode connected packs in parallel for safety. You can
be sure that these spikes are 5amps or more. I placed a Castel
reg in the circuit and it drops the spikes to a few hundred millivolts<br>
<br>
The average current draw is around 250 mA for 2 masters sequences.<br>
<br>
Hope this helps. Incidentally the regulator does not get hot.<br>

Yes.<br>
<br>
I can't find by physical inspection any "wacked out servos" or
other issues that might cause increased current load on the regulator.
So....I'm trying to find the typical (or average) current that should be
seen at any moment (instant) on a meter in-line with the regulator. Then
I'll run my set-up and compare. If I'm in the ball park (less than 1A based
on a couple of inputs so far) then the problem is not related to
"wacked out" servos, binding etc.<br>

Average current is not the same as instantaneous current, unless the only
current being drawn was just for that single instant in time. Anyway, I
will repeat, with an added quailifer, for the sake of understanding for
where to look to help you solve the problem:<br>
<br>
If you are using a JACCIO, Tech-Aero, or whatever regulator in a pattern
setup, even with a YS CDI on a shared output, and if you find that you need
a heat sink, then:<br>
<br>
<br>
Something Else Is Wrong. Check your setup for binding linkages, stiff
hinges, whacked out servos, whatever.<br>
<br>
Seriously, check your setup, OK? Just trying to help here.<br>
<br>

Actually, if you consumed 200mAhr in 0.25hrs, then your average
(instantaneous) current was 800mA.<br>

I'm running a different ignition system, but total consumption radio and
ignition) for an entire 15 minute flight is about 200 mah..200 X4 = 800
milliamps for an hour= 0.8 amps per hour So the instantaneous current
shouldn't be much.<br>

Does anyone know what the current consumption should be at idle/run-up for
a typical YS170/Hyde/all digital servos installation?<br>
<br>
I'll stick a Watt's Up meter in there to see how much I'm pulling after the
regulator.<br>
<br>
Jim, what's the current limit for continuous operation and spike/inrush for
your regulator?<br>

I don't believe a bad battery could cause the engine to rev up unless your
battery failsafe isn't set properly. Make sure it is.<br>
<br>
<br>
The first thing I would look at is the possibility that the throttle servo
is stalled at low speed. That could be pulling the battery/voltage
regulator voltage down and it could recover after you started to throttle
up and removed the heavy load.<br>
<br>
<br>
Finally I would run a one amp discharge test on the battery after it is
fully charged to see if the battery is near its original capacity. The best
way to do this is to plot the voltage vs. time taking readings every 5 to
10 minutes.<br>
<br>
<br>
Hope this helps. Let us know what you find.<br>

I had a close call today with my R921 Rx in an Integral.<br>
<br>
I noticed on taxi out that the engine rev'd up and quickly back down
without any command. At first I thought I must have bumped the stick by
accident. Then just before take-off there was no responce from the throttle
for a second or two then it was back. I thought the 170 may have loaded up
a little and didnt respond. It did that one more time before I aborted the
flight. However, I could'nt reproduce the problem in the pits.<br>
<br>
Before powering down, I checked for holds or fades on the data logger -
nil.<br>
<br>
Battery voltage droped from 8.2V to 7.8V and 7.6 under 1A load. When I
re-charged it took 350mA and I was only on for 3-4 mins.<br>
<br>
Now...I did accidentally run the battery down to like 5V during winter but
it did eventually recharge.<br>
<br>
I'm using a Jaccio perfect switch/6V regulator, Jaccio 2000mAHr (1 season<br>
