"Hi Rob,

Many thanks for your support, you will be missed as one of the experts on this forum.

Good luck, and best whishes !

"Hi Christian,

I am too very interested in the power module, because of the accurate measurements, which is critical to squeeze every bit of flying time out of the battery.

By reading the specs I started thinking about the BEC's as stand alone…"

"Randy, Leonard,
After finally be able to download RC9, due to very bad internet connections at my current holiday location, yesterday I had the first flight with this firmware.
In the meantime read the Blog post of Leonard, about the Motor Bel Play,…"

"Ok thanks, I'll see what I can find on the hardware side of things.
Don't get me wrong I do like the progress a.k.a EKF, but I do see rather inconsistent behaviour between flights..., in RC7 I had clipping up too 3000 and higher, without any strange…"

"Ok thanks, I'll have a look if I can find anything moving around in wires under the PixHawk, maybe something started to move due to wind or so...
according to what I have read in the EKF settings, you may increase the importance of the GPS over the…"

"Thanks Andy, So maybe the dropout on the Gyro was the initiator of the jump in altitude possibly ?"

"Thanks Randy,
I am however wondering why as the same platform has been flying fine for quite some time, i.e from 3.21 onwards....
At the first part of the flight when I still was in loiter the vibes are fine, it's as soon as it is gaing height in…"

"Altitude Jump during AUTO mission.
On RC8, fully tuned including Yaw without any alteration afterwards (perfect feel, no twitching in Pitch), the drone is pretty stable and has had a number of flights in the Netherlands, without the strange…"

"Thanks Andy,

Indeed the value should be lower then the original 230..., so reduced to 140, which doesn't prevent arming, and is allowing me to take off in Loiter.
Did see the fast flashing green indicator as well, so is fine during flight.."

"Thanks Henri, I do see the same figures with my Neo-8M, so reduced the HDOP value to 140 on both birds!"

"Hi Darwin,

I have seen this as well..

It has to do with losing the character set on the OSD, just re flash and make sure you have both sides powered up (digital side with 5v, analog side with 12v)...

That has resolved it for me...."

"Thanks Randy !
So a green indicator on the PixHawk, while fence has been setup, isn't valid to assume you are good to go..

Taking off in any of the GPS assisted modes is a better check.
That is a kind of misleading I think, I.e green light should…"

"I indeed do fly at a field, so don't have multi path problems which may be the reason that it's not getting a full 3D lock.

And I most of the time take off in Stabilize and then switch to AltH or Loiter while in the air, but I never take off…"
