Hello to everyone. i am new to this forum. I don’t know the rules exactly, I apologize in advance. but i have a big problem. I created a new quadcopter but I couldn’t calibrate the escs. can you help me?
esc: fvt little bee spring 30A
Motors: emax rs2306
boarding pass: cuav v5 nano
First of all, I connected the escs to omnibus f4 card with the blheli suite and made the minimum and maximum throttle settings. I adjusted the motor directions. Then I connected the escs to the receiver one by one and did a manual calibration. Then I connected the escs to the cuav card and made the connection to the mission planner. I installed version 4.07. I calibrated all sensors and remote. Finally, I selected and saved oneshot125 in esc calibration. Then I cut all the power and brought the throttle to the maximum from the remote control and connected the power. After the melody sounds, I disconnected the power and connected it again. After the beeps came, I turned the gas down to minimum. melody and beeps sounded. The last time I gave light gas, the motors worked perfectly. but when I cut off the power, reconnected and arming, the motors lost their calibration and their speed changed. so one motor was 1300 while the other was 1150. I tried all protocols (oneshot, oneshot125, dshot150, dshot300, dshot600) and the result did not change in any of them. When you cut off the power after the calibration, the calibration is broken. what do you think i can do? (I contacted cuav engineers with teamviwer. They also looked at all the settings. They also made a few adjustments. They said ok no problem, you can fly now. Today, as soon as I put the propellers on and arm, the quad crashed into the air like an injured pigeon, and all 4 propellers were broken. By the way, I’m sure the propellers are installed correctly. The motor directions are also correct.)
