Guys,
Ok I fully charged a 4s 2450mah Zippy Compact pack and flew today. This pack is not puffed and took a full charge. However, once in the air I checked the lap time and it was 5.0 sec (59' C to C). This is slow for this ship, it is normally 4.88 sec. I suspect the pack under load is not at full voltage, nothing else has changed with the ESC or timer.
Question is how do I check the pack under load?
Best, DennisT
