"Is it just me? I see Thomas' posts on the number of DIYDrones members, and I can't help but think that the trend over time is going down, not up. Is the y-axis a log scale, or something? Does anyone else thing this?"
Is the throttle controlled by the APM during RTL? During RTL due to failsafe? I ask because I've searched in the documentation, and I can't find an answer for this.Because a RTL due to failsafe implies that the receiver is sending a throttle command…
"I'd vote for just C. C++ for embedded systems feels cumbersome unless it is complex. Because the OSD simply receives the MAVLink/UAVtalk messages, things are fairly straightforward. My two cents."
"Excellent test, and very interesting! However, I think the length of time for data collection in insufficient. Some units may work better at different satellite angles, etc. A redo of this test, only with data collected for a period of time to let…"
"At first glance, it doesn't seem too unreasonable. It is a temporary restriction. If someone was planning on committing terrorism, 30 miles is fairly reasonable for a fixed wing aircraft.
However, this restriction would only "work" if this 30 mile…"
"Have you noticed temperature sensitivity in the bungee? I use a catapult system, that has proved to be reliable - I always use the same measured tension. It was reliable, until I tried launching in temperatures ~50 deg F cooler than usual. The…"
"A feature like this would be difficult to make robust. Any kinematic condition to sense a failure would likely need the opposite response from APM as would be necessary for stability in a non-failure condition (eg cut power in a free fall instead of…"
"The fuselage certainly looks fixable. Some heat, glue, and perhaps some additional re-enforcement (fiberglass, kevlar, or even tape) should make it strong. Not so sure about the wing. You could try embedding additional carbon fiber braces. It is…"
"Very sad news.
The test flight looks like it had a number of "firsts", including a new rocket engine.
"SpaceShipTwo was testing a new plastic-based rocket fuel for the first time Friday. An eyewitness told The Daily Beast that the spacecraft…"
"@Kevin:
Thanks for the reply. Yes, ceni-amps is weird. The header declaration for osd_curr_A has a comment that says osd_curr_A is in units of mA. However, OSD_Panels prints osd_curr_A*0.01. Odd.
Yes. I'm trying to have a concise method to compare…"
"I am writing a custom efficiency function for MinimOSD-extra to give percent efficiencies for horizontal flight and climb. Doing so requires the units in the math to work. Can someone verify that I am understanding the units correctly? It is not…"
"@Rob: Aircraft fly over wilderness all the time. Just because you cannot land in the wilderness, it does not follow that you cannot fly above the wilderness. [Not that I want to see or hear a drone when I am inter wilderness more than you]."
