A few weeks ago I had a wicked crash of my quadcopter (APM 2.0 with sonar). It suddenly took off in one direction (without waypoints or input from me) but eventually came back to its hover point. I…Continue
I'm just getting my 3DR AC2 up and running with an APM2. I have the ubiquitous Eurgle/FlySky/Imax/Turnigy 9x r/c transmitter. I know many folks flash the er9x firmware to this transmitter for use…Continue
"win 8 mobile and win 8 RT (in the new Microsoft Surface) are not compatible with all x86 programs, so they presumably will NOT run APM mission planner. The new Microsoft Surface Pro (due to release in January) should since it will run a full version…"
"Don't get the 4S batteries. The extra voltage won't help you. Get 3S and consider 4000-5000 mah. I have a 5800 mah which is good but a little heavier than I wanted. If you're going to run additional electronics, such as telemetry or a…"
A few weeks ago I had a wicked crash of my quadcopter (APM 2.0 with sonar). It suddenly took off in one direction (without waypoints or input from me) but eventually came back to its hover point. I started a fast decent, but when I gave it more stick to slow it down the throttle seemed to give out and it slammed into the ground.

"I'm interested in using four digital (vs analog) led strips to do a sort of animation along the arms of my quad. The LEDs would light sequentially from outside to in when the quad was descending and inside to out when it was ascending,…"
"Are you using the stock (yellow) ESCs that come in an Arducopter kit? I used those and was unable to get them to calibrate either automatically or individually. It turns out that some of the ESCs shipped by 3DRobotics have a firmware…"
"I found a post in one of the forums with a similar problem. According to that kind gentlemen, DIYDrones shipped two different types of plain yellow ESCs, one of which is not programmable (despite what the instructions say). That would…"
"certainly didn't intentionally set to NiMh. No matter what I do, I seem to only be able to get the musical "123" tone (self test) and a long beep when it arms (with throttle low). I don't get three beeps or two beeps…"
"More ESC trouble. I rechecked everything, and I'm still having trouble getting the ESCs to calibrate. When I connect the ESC directly to the receiver, I get the "123" tone indicating the self test process, but I don't get 3…"
