"I think that the 5v power supply on the standard 3DR power module will generate 5.3 volts down to a battery voltage of 6 volts or so. I have only tested this myself accidentally by drawing the batteries down to 7 volts in the…"
Fixed wing drones do work well with winds. They cruise at about 12 meters per second. They can fly for more than an hour. You get nice evenly timed photos with the survey pattern setup to fly across wind and always…"
"Event 38 has a fixed wing agricultural drone package. It doesn't support the payload weights you are after but it would allow you to prototype the system operation. I have found their fixed wing drones to be quite…"
"I managed to get a 3DR Solo with the Pixhawk 2 logging high data rate gyro data. The GYR1 data is logged at 1000Hz. It looks like the Pixhawk 2 has a low noise setup and gets full performance out of the…"
"@Anthonie That is the plan. I was going to compare the Pixhawk1 with the APM2.6. I may be able to compare the Pixhawk2 on the solo too. I am actually expecting things to be better on the battery. USB power is pretty…"
"I logged some data from a Pixhawk 1 and found that the rate noise is close to the the 0.005 deg/sec/root(Hz), single sided level in MPU6000 spec. A little higher than the spec., but I was bumping the desk at bit when I logged the data…"
"I just noticed that the Invensense ICM-20602 with its 0.004 deg/sec/root(Hz) is a single sided PSD measurement. This means that the ICM-20602 gyro angle random walk(ARW) is actually better than I showed in my early posts:
"APM 2.8 with the MPU6000 (0.005 deg/sec/root(Hz), 0.3 deg/root(hr)) is at least 2 times better than any of the HG1120s
Pixhawk 1 with its MPU6000 (0.005 deg/sec/root(Hz), 0.3 deg/root(hr)) is at least 2 times better than any of the HG1120s
"Comparing them in terms of angle random walk, the Invensense ICM-20602 0.004 deg/sec/root(Hz) is equivalent to 0.24 deg/root(hr). This is 2.5 times less rate noise than the best HG1120. The ICM-20602 is an excellent…"
"I have always liked the Iris. Even though I have a Solo now, I think the Iris is a better work quadcopter than the Solo. The Iris has both a primary rf control link and a secondary rf link for telemetry. …"
"Looked like you were close to getting it flying. Amazingly tough center section! Put the wings back on. It is worth another try.
I find that having an autopilot in aircraft(even if it is just manual flight…"
"For high stability you want the autopilot with the lower noise IMU gyros. The Pixhawk 1 with the lower noise MPU6000 IMU gyros is a better autopilot for hexacopter stability. The Pixhawk 1 uses the same processor…"
