<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 old)</DIV>
<DIV> </DIV>
<DIV>I think the Rx momentarily lost power. I'm sure if I change the Rx pack and the regulator.</DIV>
<DIV> </DIV>
<DIV>Does anyone know if this regulator can fail and interupt the supply then recover? Any explanation for the relatively high current consumption...maybe a regulator issue...high Vdrop/RDSon?</DIV>
