Good morning DIY DRONES,
You guys are my only hope as I have tried everything I can to fix this problems but it seems like an never ending journey.
So, let's me start by saying that I have followed and researched about every possible way to build a TBS Discovery with Pixhawk but my knowledge is still very limited, as I keep on reading, I feel like I have made so many stupid mistake.
So my TBS build list:
TBS Discovery w/ core.
900kv TBS motors and bulletproof escs
Pixhawk w/ GPS
4500mah 4s battery.
I have been facing so many problems since thay day I switch from 750kv to 900kv, as everybody said the samething, 900kv is way much better, better bearing, i choose 900kv for long flight etc...
After I install the 900kv on my tbs, everything started to fall apart, Mag_field is really high, over 680 :( Vibration is absolutely ridiculous (eventhough my X+Y axis is still under range but my Z is way beyond measure). My quad could not hold position or altitude, when I fly in stabilize mode it seems to be okie but when i switched from stabilize to either Loiter or Altitude hold, the quad started shooting up and down just like when you change throttle from lowest position to highest in a matter of second. I have to switch to stabilize mode immediately other it will keeps going up.
Could you guys please help me to make this right, i'm truly desperate, i have tried everything but non of them seems to work.
Please find my attachment for the log file, i have tried to fly it as long as i can to review the problems. Please DIYDrones, you are my only hope. 2014-09-12%2023-29-04.log
P/s: I have calibrated all escs, compass, etc.. I followed the introduction closely but non seems to work
