<DIV>I noticed that when I powered down and up the Rx the throttle servo
moves to a near mid point position and immediately returns to wherever the
throttle is set. It (9303) always did that. So I think the Rx lost power
and on it's return the throttle servo did it's usual thing and rev'd the
engine. It also didnt respond from idle so maybe it is stalling.</DIV>
<DIV> </DIV>
<DIV>I'll replace the servo and battery. I also noticed that the heat
shrink on the regulator was discoloured and torn so I think I'll replace
it as well.</DIV>

Make sure it is.
<DIV><BR></DIV>
<DIV>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. </DIV>
<DIV><BR></DIV>
<DIV>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.</DIV>

<DIV>Hope this helps. Let us know what you find.</DIV>

<DIV>I had a close call today with my R921 Rx in an
Integral.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>Before powering down, I checked for holds or fades on the
data logger - nil.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>Now...I did accidentally run the battery down to like 5V
during winter but it did eventually recharge.</DIV>
<DIV> </DIV>
<DIV>I'm using a Jaccio perfect switch/6V regulator, Jaccio
2000mAHr (1 season</DIV>
