hi everyone i am new to the hobby and i managed to build a full quadcopter by following the very well known $99 dollar quad from uavfutures.

ive been try to fix this one issue of my quad being very sensitive even at 10%-15% throttle or less straight after takeoff. this problem i believe is to do with my motors that may be faulty as i have had other issue with them in the past weeks when building the quad.

when i arm the quad and take off it seem fine for 1 second at a 1 high ish metre hover , but then it starts to fall very slowly , so when i correct this by adding the smallest and i mean the smallest amount of throttle it shoots up and i end up disarming it and catching as it comes down.

i have watch many video on how to calibrate and tune my quad and havent seen any improvement .
iam currently using dshot300 as my esc recommend as well as blheli .
and before somebody says i dont re correct after i have calibrate it.

so if anybody has any suggestion i would love to hear them
thanks - jack
 
Nobody explains RC Rates better than JB. This should give you a better understanding of how to control your quad to your feel

 
Sounds like his settings are off.
Perhaps try resetting the pids.
Do a board reset in the setup tab next to gyro calibration & do not load any backup settings. Just setup the modes & failsafe.
Then see how it flies. If it still persists then it's probably the esc settings as the pids & rates have just been reset.
Throttle is a thing to master. Even if you do sort it out. Have you messed with the throttle mid-point, you might have brought it right down.
Instead if having 25% throttle at 25% stick you can have 100% throttle.
Or you could have 2foot long sticks, that would counteract speed :D
 
What esc's & protocol are you using.
In bl-heli configuration tool, check all the point are where they should be.
1000
2000
I have mine at 1020 + 1980 same in betaflight. This is for other reasons.
