Auto Takeoff

Does the Auto takeoff mode work? I have only tried auto land and have been a bit skeptical of Auto takeoff feature. Continue

Voltage Fluctuations
Started this discussion. Last reply by R_Lefebvre May 2. 17 Replies 0 Likes
Is it possible that the magnetometer could become inaccurate due to voltage fluctuations? I am finding that I can loiter for around 8-10 minutes then the mag starts to drift. Yes my Auto_dec is "0"…Continue
Camera suggestions?

I am starting to do some research on cameras for my aerial rig. Right now I have been building up a 1000mm class size helicopter. The camera size isn't a huge issue but I don't want some mondo camera…Continue

"So the problem with starting a mission with a waypoint is that it *could* start trying to accelerate before the skids are up, and end up tipping over. Also, it starts moving with a very low altitude, so you could hit somebody.
What…"

Sean Whitney replied to Sean Whitney's discussion Auto Takeoff"I was flipping it straight into Auto mode yesterday when spoiled up on the ground. It took right off and flew to its way point no problem. I just don't know what the Auto Take off will do in mission planner. "

"Yes... I think so. I've been using it quite a lot. I just can't remember if I've modified anything that would make it work when it otherwise wouldn't. I don't think I have."

Sean Whitney replied to R_Lefebvre's discussion Arducopter 2.9 for TradHeli Discussion"Holy crap! you were doing 25 m/s? That seems really fast for that autopilot. How does it handle it most of the time? "
DeveloperR_Lefebvre replied to Sean Whitney's discussion Flight from today.
"Hmmm... What I was referring to is this:
// detect whether we have landed by watching for minimum throttle and now movement if (abs(climb_rate) < 20 && (g.rc_3.servo_out <= get_angle_boost(g.throttle_min) ||…"
Sean Whitney replied to R_Lefebvre's discussion Arducopter 2.9 for TradHeli Discussion"Is there a wiki page on all the changes?

Sean Whitney replied to Sean Whitney's discussion Flight from today."Thanks Lefebvre,
Once I went with a onboard mag and new GPS my problems were solved. I suppose I could tune on the Loiter Params a little more. Next flight I will try putting them more closely to stock. "
DeveloperRandy replied to Sean Whitney's discussion Flight from today.
"Yes indeed. Above I mentioned, "as long as you don't put the throttle to zero with the land-speed set that low it should be ok" but to be really picky, the land_complete flag is set before the check of whether the throttle is…"
DeveloperR_Lefebvre replied to Sean Whitney's discussion Flight from today.
"Good point Randy. But, isn't it also checking for the Throttle setting to be below throttle_min? So that would stop it from falsely triggering, no?
Nice flight Sean. Glad you seem to be getting your bugs worked out."
DeveloperRandy replied to Sean Whitney's discussion Flight from today.
"ok, as long as you don't put the throttle to zero with the land-speed set that low it should be ok. If you could read it's mind though you'd likely find that it had already set the land-completed flag to true internally. …"
Sean Whitney replied to Sean Whitney's discussion Flight from today."Yes it was set around 10 cm/s but you should have seen the first attempt when it was set at 1000 cm/s fat finger... Talk about heading for the ground quickly! "
DeveloperRandy replied to Sean Whitney's discussion Flight from today.
"Looking good! That's the gentlest touchdown in history. I guess you had your LAND_SPEED set very low? Best not to set it lower then 20 (cm/s) or it could get confused as to whether it's actually landed or not."

Manuel Zangenfeind said… Dear Sean Whitney,
I saw a video from your Trex 550 in Loiter Mode. The heli is staying very rigid in the air.
I'm using a TREX 700E and want to fly this heli with apm 2.5 version 2.91 autonomously.
Currently I want to adjust the PID parameter. The stabilize and the Altitude Hold Mode is working perfect, but I have some problems with the Loiter values.
So would it be possible to send me your PID values of the loiter mode? I think they have to be very similar.
Thanks.
Nice Greets from Austria
