"Agreed - capacity is not up, but charging ability is. Also, the normal laws of physicals still apply - dumping say 10A into a 5cmx5cmx15cm space is gonna generate heat. And you're gonna need a *really* thick cable...
More capacity would be…"

Hi All,Just a quick heads-up for those of you flying with an onboard camera and using GPS. I use a gopro with no problems, it doesn't seem to interfere with anything.However today I decided to try a…Continue

Wiki NinjaGary McCray commented on Dave C's blog post Lithium battery dreams
"Actually, we already had a blog 3 or 4 weeks back on this University of Illinois battery technology.
Basically using micro-cellular construction they have much better denser current path.
Batteries don't really have any more capacity but you…"
Chuck commented on Dave C's blog post Lithium battery dreams"@Dave good to know I am not the only person that makes designs with a "Need X Component Developed" sticker on them. Battery density is one of the main hurdles to overcome for the next wave of technology breakthroughs."
DeveloperR_Lefebvre commented on Dave C's blog post Lithium battery dreams
"Seems like these massive battery breakthrough stories come about once a month or so... but nothing changes very fast in the actual market."
Dave C commented on Dave C's blog post Lithium battery dreams"Yes indeed it wasn't the best article, I'm sure we will hear more in time. It just had me staring at a wall with designs on a set of my own wings...
It does say that it can be optimised for more juice or increased life.

DeveloperJohn Arne Birkeland commented on Dave C's blog post Lithium battery dreams
"According to the article it has higher power density, but not higher energy density then current batteries. So it mean that you can draw more current out of the battery quickly, and charge it quicker. A higher C rating using current LiPo terms. But…"

Dave C replied to Matt Gunn's discussion GRID V2 does not work. Developers, Please Read."I'm sure the devs are not ignoring this, they are just very busy and most of them are devs in their spare time and for free. This is opensource 'DIY' after all.
I'd love to help but I'm no programmer, i would suggest…"
Dave C replied to Trent Reeder's discussion Platform for Aerial Photography"Two questions really.
1. How much area do you need to cover? This relates to how long you need to be in the air and how fast you have to travel.
2. How much have you go to spend? I will elaborate when i hear your budget ;)
Maybe give us an idea of…"
Dave C replied to Felix P's discussion Apm 2.5 and some less wanted behavior ."First of all what are you powering off your APM? And how is it powered?
Do you have any servos connected, are they powered from the APM's rail?
Those dji motors will not take that sort of abuse - you can run them on 4s and 10" if you…"
Dave C replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"There is a parameter in the advanced list (i forget what it's called now but its obvious) that delays the start up of the telemetry for a specified number of seconds. This should solve your problem.
I use 5 seconds and I've only had…"
Dave C replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Yes RAW has be renamed IMU.
Try reinstalling MP using the msi. That usually fixes any probs I've had with it."
Dave C replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Yeah, I've had this too. I post videos with music, youtube bitches at me and disables the video for about an hour. Then the restrictions magically disappear and the vids become available.
Maybe it's due to my awful taste in music ;)"
Dave C replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Agreed, leave the crashing to the development and testing teams.
The beta releases should only been flown by experience APM users who are fully aware of the risks.
I for one love it when i have an unexplained crash (very rare these days) or…"
Dave C commented on Joshua Ott's blog post Thirty days of Awesomeness (#3): FollowMe test."To clarify, what i should have said was 'one could even walk the course, without clicking channel 7 at every deviation from a straight line.' "
Dave C commented on Joshua Ott's blog post Thirty days of Awesomeness (#3): FollowMe test."Yes thanks Hughes, I've been using that for a long time now.
What i want to see is an upgrade, where a new path can be set with the tablet on each run, it would still be a live follow, but along the course, rather than cutting corners. I…"
