I have problem with my new copter. repeated get potential thrust loss during loiter, also altitude hold mode. may be wrong tuning ? would you help me please everyone. above I provided LOG file.
Motor = EMAX ECOII2306-1900KV
Props = 3 blades 5 inch
ESC = Hobbywing Xrotor 65A 4in1
Nope, that is simply too much weight for that powertrain.
You need other battery, or other motors or other props.
Thanks for response.
I use Lipo 4S1P battery with 45C and 5000 mAh Capacity, Is not enough?
Do you have any advice? which brand ? motor, props and battery?
See section 1.1 of this document.
Check the hover data using ecalc, copter. Very useful. Most probably lack of power on the props.
Ecalc should give you a hover power which should be at least 50 % less than the maximum power for a given combination of prop/motor/battery V/weight
VERY DANGEROUS TO FLY if it is less than that! How I know it…
To calculate, you absolutely need to know the weight of your copter.
If you do not want to go into these details:
Either increase prop size, by an inch
Or: go to 5S or even 6S if the motor can tolerate that.
Or try a much smaller battery.
Without going into calculations and eyeballing it, I think your copter should be flying well with a weight of about 700 grams max… And a 4S 5000 battery weighs about 450…500 grams, so you are probably overweight.
You will have to retune afgter changing these things.
