Hey everyone,
I'm new on the forum and have just signed up after searching for my problem online and noticing in this forum.
According to the title, i'm having issue with trying to spin a motor. When i try it, it makes a scrapping sound. There are many posts here in the forum about it (which i have seen) but usually its about old motors, which have crashed, which is not my case.
I have a new BLHeli_32 ESC (upgraded to 32.8) and some new motors, which i would like to test in my bench. The ESC is a iFlight Succex 55A and the motors i have tried out (which are brand new and used them today) are Racerstar BR2814 1000Kv and T-Motor AS2814 1050Kv. I have been trying them out with an APC 1050 pusher propeller. When i test the motors, both with and without propellers, i hear a scrapping noise (i can try to record it), when the throttle is above 40% without propeller and above 30% with propeller. What is strange is that it seems that at 60%, there is no scrapping noise (just at 60%, under and above 60% there is scrapping noise). The problem isn't from the circlip scrapping on something, but can be internal? Which would be strange that it happens on two different brand new motors. It seems clearly an ESC timing problem, from what i understood. I started by using the default settings and then changeg to the settings laid in Oscar Liang blog (The Best BLHeli_32 Settings - Oscar Liang ) and then changed for the settings when you have ESC desync and now i have increased the timing to 27 and have reduced the maximum acceleration. Unfortunately, i'm not having success and i keep hearing the scrapping noise and the motor doesn't produce the thrust it should produce (with the scrapping - above 30% throttle with propeller - , current isn't constant while without scrapping it is - under 30%). I should also add that i'm using a bench power supply capable of 10A and i'm not getting nowhere near that amount of current (it is set to its maximum) - don't know if this can influence something.
Does anyone have an advice/has this already happened to him/her? Which blheli ESC configurations can i try out to sort this out?
Thanks in advance
