I have a question about how RtL works in 3.3I was at 1000+ meters, when engaged RTL. My RTL altitude is set to 100 meters. So I expected plane to glide towards me till it reaches 100m and then continue with motor if still didn't reach me.But…
"Tried latest OpenLog firmware. As well as "lite" version with increased buffer - still no luck"
I tried using OpenLog SD card logger to record onboard tlog files. But I'm getting strange files, not readable by Mission Planner.Here is what I did:1. Connected OpenLog to the telemetry port of APM 2.5 (Gnd, +5v, Tx), while telemetry radio was…
"+1 on compass issue. Double-check compass orientation and settings."
"Very nice experiment!
I'm having the very same issue, but when I first faced it, I could not find a good discussion thread on this. Is there one I missed?
My question is - why does it not gain altitude on speedup if there is a pressure bubble? But…"

"Interestingly, I got the very same problem on my new Hexa with PixHawk.
As per logs, vibrations jump on both IMUs. And it looks, like full throttle is given prior to increased vibrations. So it might be, that vibrations are a consequence of full…"

"Should CRate look like first derivative from RelAlt on dataflash logs?
They both should be based on Acc + Baro, but it looks like Acc component for CRate has higher weight in 3.1.4 At least in my case.
As vibrations increase, CRate drops down into…"

"Ha!
I've just notice, that whenever vibrations increase, CRate drops. (See image), but!
As per Docs:
RelAlt: Accelerometer + Baro altitude in meters
CRate: accelerometer + baro climb rate estimate in cm/s
So how can CRate be negative, when…"

"I was able to replicate thisseveral times. And Now I'm certain, that this relates to increasing vibrations in some conditions.
However, here is interesting part of today's log:
There is clear increase in vibration, as I tilt copter forward and…"

"Can't find any reason other, than RelAlt dropping down... Will do more test flights next week to see it that happens again."
I had strange issue yesterday. While in ALT_HOLD mode, quadcopter suddenly starded climbing like a rocket. Did not respond to my throttle input until I switched to STABILIZE. Then it got controllable again.I'm not a big log expert yet, so would…
"Sorry if this has ben asked before, but
For FrSky telemtery - Is there any reason to connect:
1. IO Board Tx to APM telemetry port. Looks like it does not need to send anything to APM.
3. A6 Pin to FrSky receiver's TX. Does it need to receive…"

"Very cool!
Are there any special sensors on the copter? Or is it based on regular Acc. sensors?"

"@LTMNO, thanks to @Jani - that is exactly what I did.
To make it simple I just take V(in) from balance port of main battery."

"As a temporary workaround, voltage can be read by receiver itself (A2), just need to split voltage wire and link it to receiver. So we have temporary workaround :)
This is really great project. Thank you!!!"

"Just tried the new MAVLink/FrSky v0.3a with FrSky
Everything is working good, Great job guys!The only Issue I have is voltage reading (See the video):
