"I couldn't find tabbed cells so I bought a cheap welder and welded them myself.
I wrapped the cells in heatshrink and made small cuts near the ends of each cell so I could insert a custom made balance plug. It was a regular balance plug with the ind…"

"Hi Dimitri

18650s have higher energy density by weight. 

They have low power output compared to LiPo batteries, but 4-5 amp at cruise is easy.

I used them for my long distance flights

"Does the drilling drone have enough range to get home, or does it do a mid air rendezvous with the helicarrier somehow? "

"Hi Rogerio
Is BMS battery management system? No nothing like that. I did see the charge of each cell when charging them and they were very consistent.  The balance plug system was quite fiddly so I would only do a balance charge every other time.
I…"

"Hi Rogerio
I used Panasonic 18650B Li Ion batteries. 6S 9P = 30600mAh total. I built them myself into 6S packs, it was a very DIY approach. I bought a cheap welder to weld them together, and heatshrink to hold them together. I used some JST leads th…"

"Hi Rob_Lefebvre
I didn't read, or recognise the significance of the no-load current comment you wrote (on September 14, 2016 at 2:52pm)
Seems like you were averaging about 4A, while using a power system designed for 65A.  The no-load current of that…"

"JB, no I don't, not as such. Do you know how to calculate prop efficiency from the telemetry data?
Can anyone confirm my understanding of the physics is correct?
Whole power train energy cost in level flight is simple, power=drag (or I guess, batter…"

"I'd be really keen to see your post, and try your idea Andrew. Thinking about JB's comments above, the aggressiveness of the climb might not matter too much. If you were only half as aggressive as ideal (say because of battery power limitations) you…"

"Thanks Naish
That is 7.8% more power for the same weight. That should give about 35km more range in perfect conditions, about 30km more in the conditions I experienced. 425 km + 30 = 455 km. "

"Thanks for all the support, and suggestions. I'm keen to try a few of them. I actually didn't test half the things I would have liked to. Some because I didn't have time, others because they were too hard, and of course lots that I didn't think of -…"

On the weekend I did a 425km flight with my Vigilant C1.Setting a new distance record is something I’ve been slowly working towards ever since flying 301km with the Cyclops EPO plane in 2014 John Smith and Gene Robinson of RP Flight Systems supporte…

Hi, I'm a bit confused by the options to run servos at 7.4V on a Pixhawk.This warning appears on the page http://ardupilot.org/plane/docs/common-powering-the-pixhawk.html#po... confirms you can do it, but doesn't offe…

"I see a couple of very simple solutions put forward including wrostek's under wing, or Cala's option sticking out of the side of the fuse. 

I have an underwing mount with a homemade servo gimbal to stabilize roll, it has a range of about 30 degrees…"

"You're right, that position offers no protection.
When the camera is worth 5 times more than the airframe it would be worth finding a position that offered some protection."
