I pretty New here, so any help at all would be appreciated.
Here is My Set up Info.
Flight Unit - Pixhawk
Con fig - H- Quad
Motors - Turnigy Multi-star Elite 5008 KV 330
ESC - Afro 30Amp
Battery - Zippy 8000, 6 cell Lipo
Tx - Turnigy 9xr
Module - Fr Sky DJT
RX - D8R-11 Plus
Telem - 3dr 915mhz
Its running the newest Stable release of the Firmware - Arducopter V3.2.1 Quad.
Ok Im pretty Sure thats it.
Ok So here is the problem.
When I Arm Pixhawk and the Tx, They all spin up equally. YAY
Next When I give it say 1/4 throttle it seems that Motor 4 will go to 1/4 throttle perfectly.
I belive that Motors 1 and 2 speed up but not to the speed that motor 4 is at.
Motor 3 wont even speed up. To get motor 3 to even change speed I have to go to about some more that 1/2 throttle. BY that time Motor 4 , 2 and 1. Even if motor 1 and 2 aren’t spinning at the same speed of 4 is putting enough power out to flip the copter.
So I recalibrated The Esc using Pixhawk.
Worked fine but problem still there.
So next I swapped the Esc from the 3rd Arm to the 1st Arm and vice - versa
Problem stayed with the 3rd arm,
Next swapped the 3rd motor to the 1st arm and vice - versa
Problme still at 3rd arm.
So this means what ever goes on the third Arm.
Completely stumped I then see what would happen if I plug in say Arm 4 into the 3rd port from the pixhawk.
So effectively making Arm 4 the new 3. Anyway with Props off I again try and now the one not spinning as it should with the rest is arm 4.
SO I believe the problem is in Programming of the Pixhawk.
As I had previously the Turnigy 3508 kv269 multi star elite. and Alfro 20 a ESC
which never had this issue, but was forced to change them after the Quad could not lift off.
WIth These new one Im sure I can Lift off because I can Flip it O.O
Anyway Guys Like I said Im new here ANY Help would be appreciated.
