Vehicles - MultiRotors / Re: Sudden crashes on AltVario
« Last post by vgwit on September 22, 2018, 08:34:55 pm »
Input page Throttle Neutral is 39 above minimum.

Have tried to look at possibility of ESC firmware upgrade. But BlHeli Configurator can not read my ESCs. I see serial port connected but after a while it disconnects and says to change port or reboot.

My ESCs are DYS BL20A with BlHeli firmware. So today I've tried to change output mode from PWMsync to OneShot125 and motor stattering with lowest motor disappeared! Have made a couple of flights in AltVario  without crashes. Hope it was the only reason of my headache last weeks. Next plan is flights in Rate mode.

I used GY-511 from Banggood, there works fine.
How did you know that this module is supported? Is there some documentation about supported modules or chips?

Output page Neutrals should be high enough to run motors when testing with Output -> Test Outputs

Important, and you didn't mention it:  Input page Throttle Neutral should be about 40 higher than Throttle Minimum.

Thank you Cliff.

In video I've posted above I intentinally started motors more quickly than I usually do. Here is a couple more with slow start.

My neutrals are 1028 and was like this on CC3D. Will try to increase them.
And an important note. I saw the problem in Rate mode also but did not recorded a video. Will do it today.

formidable.
merci de ta réponse encor une fois très claire
je vais testé tout cela demain
pour le easytune j'ai pu le voir ya quelque temps mais cela me faisais peur pour le quad du coup une question arrive sur sa, et t'il possible de faire se réglage en plein vole ou bien le posé a chaque changement ? car j'ai rien trouvé de convaincant sur YouTube
merci et bonne nuit

Firmware General / Re: F3 based flight controller firmware support

This thread should have enough information to get you going?  The F3 code is not in the release version (16.09), but it has been merged into "next".  Build or get a recent next.

It seems that motors go fairly high as soon as you start them.  Make sure your Input page Throttle Neutral is about 40 above Throttle Minimum (typical setup that has throttle going from 1000 to 2000 some transmitter protocols have different ranges).  Also all your Output page motor Neutrals should be about 80 above Minimum (typical setup that has motors going from 1000 to 1900/2000; some ESC protocols have different ranges).

I had some ESCs that came with old firmware and did not like to start quickly, but would start slowly, so doing Output page Test Outputs would work fine, but some motors would not start when about to take off.  I was in Attitude mode and it was always the lower motors (very slightly lower because of ground unlevel) that would not start.  That was because they were being asked to start at a higher throttle then the "higher up the hill" motors.  Once the motors were started, I didn't have any problems.  Temporary solution was to very slightly tilt the quad to elevate the motors that would not start and retry.

A test to try:  Using Attitude mode, set it unlevel by say 10 degrees and see if the lower motors consistently have a harder time starting.  You can then just manually hold the quad very slightly tilted with the hard starting motors higher.  You can also switch to using Rate mode for a test.  Rate mode should not have this problem.

Wenn ich der Copter "armed" ist laufen die Rotoren gleichmäßig.
Ich halte den Copter fest, damit er nicht sofort fippt oder abhaut. Sobald ich den Gashebel auch nur 2mm bewege geht das Ding ab wie Schmitts Katze.

Hat jemand ne Idee was ich noch machen kann?

Nur der Vollständigkeit geschuldet. Das Flippen kam daher, dass mein CC3D um 180grad gedreht montiert ist.
Das ist mir erst später aufgefallen. Wenn der USB Port nach vorne zeigt ist der CC3D um 180 Grad gedreht...

Wenn ich das schneller gemerkt hätte hätte ich mir Rotoren für 5€ sparen können ;D

Und zum Festhalten des Copters immer Lederhandschuhe tragen... Mir fehlt aktuell einiges an Haut auf dem Daumen, die Rotoren sind mindestens so gut wie Küchenhobel.. :'(

Dann sind die Gaswege erstmal ok. So wie Cliff geschrieben hat, die Mitte ca. 50 msec über dem Wert eingestellt, bei dem im Output Schirm die Motoren anfangen zu drehen?

Danke euch, ich hab es hinbekommen. Ich hab an den Max Werten im Output gespielt.
Als Default hatte ich eine Range von 1000 - 1900.

Der Motor Läuft bei ca 1030 an und hebt bei 1350 ab. Wenn ich den Max Wert auf 1600 reduziere ist der Gashebel relativ zahm.
Damit werde ich jetzt mal anfangen zu spielen...
