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…Continue
"We have implemented elevons on our X8 Quadplane and were wondering if we can have both Elevons and differential spoilers, since we have two servos and control surfaces per side. What would it take to enable this functionality?"
"Did you try the RTL while on the ground at the boot up point? I did that and the throttle didn't work. Once I tested it in flight the RTL worked perfectly with throttle control. The APM must know that it is not in flight and already at launch…"
"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 below the configured window in APM, the throttle APM uses during RTL must be either preconfigured or adjusted to hit an airspeed.Note that I am not asking about the throttle value needed to elicit a failsafe. I am asking if APM commands a nonzero…See More
"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…"
"Hi Dave, I tried my first auto land, it was unsuccessful, insha Allah I will try again. I was intreuged to read that even in cross wind the the APM coped with the landing......crabbing at 45°......masha Allah.
Was there any particular…"
"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…"
"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…"
