RTL Default Throttle Setting?

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?"

Jim Palmer replied to Lockhart's discussion RTL Default Throttle Setting?
"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…"

"Ah! It is a graph of the rate, not of the volume. That makes sense, now. Should have caught that. Thanks!"

"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?"

RTL Default Throttle Setting?

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

Lockhart commented on Luis Alves's blog post AlceOSD - Graphical OSD for APM/PX4
"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."

Lockhart commented on Thorsten's blog post u-blox M8N - ground planes, antennas and positional accuracy
"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…"

Lockhart commented on Chris Anderson's blog post Gizmodo: "The FAA's Drone Ban at the Super Bowl is Absurd"
"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…"

Lockhart commented on Eric Compas's blog post APM response to catastrophic air frame/wing failure?
"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…"

Lockhart replied to Pedro's discussion X8 crashed... will it ever fly again??? in the group X8
"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…"
