    When do you land? I usually after 30% low battery warning signal, descend the craft and fly low to ground and close to me a lil bit more. So i land at around 16-20% is it ok?

    It is but give yourself time and you do NOT want auto land to kick in as most people panic and then things go horribly wrong.

    It depends what's being filmed - and if it's a one off (like a train going over a bridge or similar) then stay out as long as possible. There's only one chance to get a good shot! Under test conditions and normal use come back in, when the first warning goes off come back in and land. One every 30 flights or so, I take it down to 8% by hovering and holding the throttle up to keep it in place. Makes hand catching a wee bit interesting.

    Here's one of the stay-out clips.

    Is that Thomas the Tank engine ?

    Do you have warp capability to zap from each side of bridge as well ?

    :)

    It was done with 5 aircraft - 2 V+ and 3 P3As. We were expecting it to be a lot slower as the few miles up to the viaduct is on a fairly steep incline and there is a station about half a mile after the crossing. However, he was on full beans and was across the viaduct in about 10 seconds!

    This is ok if you have left the battery warning and critical level settings at 30and 10%

    I try to be at the landing point or very close at 30% battery. I don't know that I've ever pushed landing past 20% battery. I see nothing wrong with landing at 20% but at that 10% is a safety buffer. I've been in situations were I've needed that buffer, hence the few times I've touched down at 20%.

    I think the bigger issue is the design of a lipo battery. They give high voltage for a maximum time and then drop off _very_ quickly. Granted, this drop off probably won't happen until 8% or 5%.

    I have my warning at 20% and critical at 15%. About 70% of the time I land above 30% remaining; it just all depends.

    Usually between 30-40%. Often I land in the low 40's because I've had a long enough flight to be satisfied and since I never know when the heck I'm gonna fly that battery again I prefer the storage charge for a possible extended time be 40% and not much lower.

    I just switched mine from 30 to 20 and critical left it at 15

    Yeah I was just wondering the same thing. Hope it's not a bad move

    Sorry what does "unil whatt" mean? Is that a brand name of a third party battery manufacturer?
