"Hej Maarten, today I ran into the same problem. Could you explain the solution in more detail? I tried to research but could not figure out the solution. Kind regards, Sebastian"

Maarten Heuvelman commented on Nick Sargeant's blog post 100km+ in the X-UAV Mini Talon
"Hi Nick, The problem I have is an "Overshoot" in altitude during a decent. So going from a waypoint with an altitude of e.g. 10m to an waypoint with an alititude of 5m the mini-UAV goes as low as 3m after which it levels to 5m. It is an…"

Maarten Heuvelman replied to Maarten Heuvelman's discussion Nearly crash due to heavy overshoot of altitude during decent.
"The basical problem is an 40% overshoot at a decents, such as decent from 10m to 5m, in between the altitude goes as low as 3m. Yesterday I tried changing the PTCH2SERV_D from 0.06 --> 0.02 --> 0.01, this had no noticable influence. Today I…"

"Today I did some more experiments; I changed the PTCH2SERV_D from 0.06 --> 0.02. Unfortunate I could not do the same flight, but I tried to setup a simulair. Perhaps it helped a little, not sure. What I notice is that going from one waypoint to…"

Nearly crash due to heavy overshoot of altitude during decent.

Flying in Auto mode my plane made nearly crashed in the ground making a right turn and decent.After waypoint 4 a right turn and decent  from 20m to 5 m was requested, however the plane fall to 40cm (above ground), then plane corrected to the requested 5m. After this it made a perfect safe (auto) landing, as programmed.Before this flight I did an Autotune flight (tuning roll and pitch). (unfortunate no log)Something is completey wrong, but I have no clou what ??See the attached, parameter_file,…See More

Heavy throttle overshoot when lowering altitude

I have problems tuning my TECS.When my plane in AUTO mode and a lower altitude is requested (going over to a new lower waypoint) you see and hear clearly that the trottle is reduced too much, the plane drops fast in altitude, and the is corrected by an higher trottle again. Which parameter do I have to adjust to get a smoother transition ?I have no (reliable) airspeed indicator so it is currently not used.Best regards Maarten…See More

"What is the difference with a normal 433MHz telemetry solution ??, can you make a comparisson table ? 5Km with 20dBm is nothing: The 5Km path loss at 433MHz is around 100dB (using isotropic antenna's) so with 20dBm transmission power you have…"

Maarten Heuvelman replied to Guillaume Jouvet's discussion Most reliable way to get the airspeed on fixed-wing?
"Dear Andre, I see indeed an small increase of airspeed when I pu my finger on the pitot tube, is this because the air is a little compressed as my skin goes a little into the tube ?? What is IAS ? Best regards Maarten"
