hey ,yeah seems like that log was to old... with a newer one it works!

just one question.... when i click on go home summary there it says mismatch.which mismach is meant by that?

and what does moving heading mean?

Hi,

When RTH becomes active your drone is first turning to the home direction and fly that heading to home.
Mismatch is between the heading to home and the actual moving heading.
If all is OK there is no mismatch, well withinh few degrees is normal.

like this one....(spark data is the heading the drone is facing, to home is the heading it should go to gohome and actual is the moving direction the drone is actual flying!)

and what does moving heading mean?

Moving heading is the actual move direction of the drone.

With zero wind and only fwd pitch they are the same ; drone facing a heading and drome moves that heading.

Flying at lower speed drone moving heading is not always the direction of the nose....
(if ofcourse only fwd pitch is applied, only roll means 90 degrees offset of the nose heading)

Thank you! Very nice program!

So if the moving heading is different from the spark data heading the drone is not flying straight?

The heading in the main screen is the heading of the drone, so the direction of the nose pointing.

If the moving headin is not the same it does say something....but difficult to analyse cause its a complex of items who causes this. (input stick, wind, turbulence. yaw/imu mismatch maybye, etc etc)
If you see a lot of flights (preferable your own cause you know what happend) you get a feel to interpret this data.

Its usefull to see a RTH into heavy wind! Drone heading is OK to gohome, but moving dir is 180 the other way....

Okay thank you! Another question: is current the motor output?

Spark_Pilot_XxXx Posted at 2018-10-16 10:16
Okay thank you! Another question: is current the motor output?

nope, not all GO4 app version record the current for the the motors, so its a amperage value

Sorry ,what ist an amperage value???

Oops, uh   U = I x R   > voltage = ampere x ohm.  if this doesnot ring a bell, do some googling

A picture is worth a few words


V = Volts
P = Power (Watts)
I = Current (Amps)
R = Resistance (Ohms)

Oh,okay! Thank you!

Hi Goody,

Thank you, enjoy my FRAP !

And still busy and adding things to FRAP,  i have seen a flightrecord with more than 12.000 records! (wich i now my limit, see if memory can deal with more)

cheers

Nice work on the program!

Hi BumblerBee,

Thanks! can you make a screenshot what you exactly mean? Sent it to JJBsoftware@gmail.com please.

This seems to be a fantastic program.  Is it freeware? shareware?  Is there a website that describes it?

If you are referring to JJBspark's FRAP, it is Freeware.   JJBspark has been very kind to provide his program without charging for downloading and using it.

Hi MAPilot,

Just download and start to use it. If any questions just ask me (here of via email [read in FRAP] ).
Program is kind of self explaining, just click all buttons and see what happens  :-)

cheers

Thanks.  I'll give it a go.

Is this open source as I am a UI designer and was wanting to build a better looking UI for it?
