[NSRCA-discussion] JR DSM glitch - trouble-shooting.

[cchariandy at yahoo.ca]

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