But without any success, It is an agricultural hexacopter with 24 inch propellers T-MOTOR P60 340KV Brushless Motor x 6
T-Motor Flame 80A x 6
T-Motor MF2211 Folfing Propeller x 6
And a quad controller pixhawk v5 nano
Battery 12S 22.000 Tattu 25C x 1
Without any weight, it flies perfect, I did an autotune and it did it without any problem, when filling it with 5 liters of water it also worked according to what was programmed, but when filling it with 9 to 10 liters, it only raised about 70 cm from the floor and it turned uncontrollable on himself in yaw i suddenly descending, turning on several occasions.
Excuse my grammar, English is not my native language.
I am new to this, but on the face of it you appear to describe a lack of sufficient power to lift the heavier load. The limited climb ability suggests to me an inability to rise out of ground effect.
You haven’t told us what sort of battery you were using. Insufficient current capacity could be the cause of your problem.
Posting a flight log might enable one of the experts here to pinpoint the cause of your problem.
I think that you have the motors tilted, or your ESC are not properly calibrated because whereas motor 2 reaches the maximum, motor 1 is only about 1400us:
T-Motor told me they don’t do this on any of their ESC’s. I’m not suggesting a parameter value just noting how they replied when I asked the question.
I kept seeing that posted also and then while helping someone with Flame ESC’s they said they couldn’t get an answer about it. I emailed Sales/Tech support and they replied right away saying they don’t have that function and that it is typically done on the Flight Controller.
This makes sense to me because they don’t know what motor/prop combination will be used with them unless they are supplied as a Combo-pack which of course they offer.
Hi Dave, the engines are in the correct order, in fact with 5 liters, I fly perfect, do the missions and apply the product in flight, but I have never been able to apply more than 7 liters
Yes, now that you mention it, it makes a lot of sense.
Can you test the rpm of each motor under heavy load? Maybe there is an electric problem with some ESC or motor. For example a bad solder point increases the resistance and makes the voltage drops under heavy current events, like when you try to lift more kg.
Can you post a log from a successful flight with 7L?We need to look at a flight off the ground with some load. It would really help if you had current logging.
Hello everyone, thanks to those who collaborated in the solution.
I tell you that the problem was the calibration of the ESCs. The maximum pulse was 1760 and I managed to upload it to 1986 and it works perfectly.
