"Pretty neat. What's the benefit of a system like this over a small landing pad than transfers power? Seems like a lot of extra weight on the vehicle for this approach as well as having to push more current since the vehicle is hovering."
"It is not required... It falls under "Target UAS Requirements (In addition to minimum requirements)" column not "Minimum UAS Requirements""
"I think the blame falls on both sides but more responsibility should be taken by the companies, in this case 3DR, to emphasize the complexity of these machines and provide a path to learn the ins and outs of how to operate and understand them. I…"
"I usually don't jump in on conversation like this but your suggestion is way off base. The option to perform RTL with a specific behavior is %100 dependent on how you operate. What you believe to the correct behavior may result in hitting an…"
"If you are going to be flying a GoPro the CM3000pro is an amazing gimbal. 32bit Alexmos with dual IMU and slip ring on the yaw axis all ready to go out of the box. I've been loving mine. …"
"FAA officially announced it Sunday morning... http://www.faa.gov/regulations_policies/rulemaking/media/021515_sUA..."
"While stick and rudder skills may not translate well to flying a drone, the knowledge gained from earning a private pilot liscense is essential. COAs I've been apart of in the past required our crew to have at the minimum passed the FAA Private…"
"Are the low voltage cutoffs disabled on your speed contollers? I havent looked at your log but maybe the LVC is starting to kick in on the ESCs"
"The EKF is much more robust as it leverages multiple sensors (baro and GPS for altitude for example) and it much more immune to sensor glitches, failures, and vibration. I highly recommend using it."
"It is definitely possible the video tx is interfering with GPS since L1 GPS is 1575mhz, not to far from 1258. Try killing the power to the transmitter and see if GPS improves. I had a 2w on 1258 over a foot away and it still severely impacted GPS."
"Depending on your configuration it could be interference from your setup. Mount the GPS up and away from the body. I had the same issues until I shielding the plate my GPS mounts on with copper tape."
"There is a differential GPS solution in the works that requires a ground station with GPS to send corrections to the air vehicle. "
"Redundancy. The pixhawk will use which ever GPS is healthier. "
"If you are using a pixhawk make sure to do an accel cal since the EKF will use both IMUs now"
"I meant current but capacity increases as well in parallel."
"I didn't say cells in parallel doesn't increase the capacity. I said it doesn't increase the C rating. Maybe I wasn't very clear. Hopefully this is better: Say you want a battery pack with 10,000mah of total capacity. If you made it using a…"
