Guys, thanks for the discussion on this topic, I’ve read the entire thread with great interest and have learned a lot.
None the less, I still have a few questions. First, after reading the release notes with the latest firmware update 1.6004v, it sounded like it was meant to help (not necessarily solve) some of the issues related to cold weather flying and rapid battery drain that could cause issues. I’d be interested in this groups opinion in this regard.
I flew today in -8C after the FW update and had no issues. I did take all the recommended precautions like fully charging the battery the same day, the battery was kept warm up until minutes before the flight, I hovered for a minute as suggested and the battery/craft temp was ~20C before a flew any distance. I was easy on the stick at all times and the ascending rate did seem a bit slower than usual (I understand that this is on of the safety features of the new FW). The battery performance, as far as I could tell was excellent. I probable could have gotten at least 17 minutes flying time but my fingers were freezing so I had to land after 15. Does this forum think I was taking unnecessary risk flying at this temp. If so, I guess I’m grounded for the next three months until winter’s over. Which brings me to my last question.
I understand if I prepare the batteries for long term storage (several months) by draining them to 40-50%, it sounds like the batteries will eventually go into hibernation mode. I’m I right, and will this degrade the performance of the batteries? I’m I better off charging and draining the batteries over the winter months if I can’t fly because of the cold? |
