    Thanks. Don't have a boat, but maybe rent one and haul up there. They do have rentals on Saranac, so that might work too. Never tried flying from a boat. Might be something to practice on and maybe head up there when the leaves change color, although I've done that before and finding lodging...

    Readings were from my lipo alarm right at landing, then used a 2nd lipo tester about 1-2 minutes later. Cells were in the (edit out 5.2- 5.4) 3.52 to 3.55 range if I remember when I landed.

    Asking again, as I'm confused. Landed with cells in the 3.55 range. Put 7438 mah back in. Going to redo test today on another battery. Have 6 and they are all pretty new. Resistance is under 2ish on all cells. I'm confused because, 3.5+ range shouldn't be hurting my battery. Battery...

    Are you sure you don't have your props on upside down? Have you calibrated your radio?

    Ok, I just did a test tonight. I flew 1 of my 80000 6s batteries till my alarm went off. Here's what I got. Landed with cells in the 3.55 range. Put 7438 mah back in. Didn't write down the ir values, but it's a good battery and during charging the internal resistance values are around...

    I live about 4-4.5 hrs from Lake Placid and have been contemplating maybe a late summer or fall (when the leaves turn color) 2-3 day trip up there for some flying /filming. I've been there a few times, but that was a long time ago. Curious as if you would be willing to share some accessible...

    Old Man, service is worth something. When I buy, I weigh price and service and can go either way. So far on batteries, I've opted for price. I've never used either Maxamps or Thunderpower, but just googling them, they seem to be pretty much the same price on the 5000 mah 4s, but max amp a...

    I have 6 of the 8000 6s nano techs. So far, all are good as I've not pushed my flight times so no real stress. Curious, how do you replace a cell on those in case I ever run into a bad cell. I have that on 2 of 5000 4s batteries, 1 hard case, 1 soft, so maybe I can learn something today.

    I have a 850mm x8 w/ 3520 Avroto's. I fly 18-20lbs w/ 2x8000 mah 6s 25c batteries. Also a 650 quad with KDE 3520's. You mention you generally fly about 8-10 minutes but can get around 15 minutes. I have similar situation and am curious as to what you think the overall effect on battery...

    My earlier post was meant to infer something on the order of do you push the published calculated amps and have some overhead? Do you trust the manufactures numbers or wait for real world confirmation? When I bought ESC's for my 3515's and 3520's, I used the 100% throttle %'s plus some for...
