Hi i recently build my first quadcopter and made quite some rookie mistakes. But i'm a bit stuck at the moment and i hope someone could help me.
So after i build it and hooked it up to cleanflight i found out i had put all my motors in the wrong direction. After moving all the motors to the right place and make sure the failsafe was right and stuff i was excited to fly.
So on a windy day (yes i know, i read it everywhere don't fly on a windy day especially when it's your first flight) i went out to fly. On a local dirtbike track i waited for the wind to calm down a bit and then started up my quad. Crazy enough it actually flew, it came a meter of the ground, i was able to fly it forward a bit and turn.
That was the end of the good part because after about 15 seconds it suddenly crashed. I found out that when i switched the motors i didn't switch the uhm... motor shafts? so the motors weren't self tightening anymore and one of the props came off during flight.
When i came back home i made sure the motors were self tightening, put a new prop on and was ready to try and fly again. For my second attempt i went to a grass field since it would be a softer landing in case i crashed. When i took off on the grass field the quadcopter immediately crashed. it went up for about a meter and then just flipped. I tried again, and again... but it just kept flipping over. Got back home and tried figuring out what was wrong.
So i checked:
- If all motors were spinning in the right direction
- The motor numbers corresponded to the motor numbers in cleanflight
- Re-calibrated the ESC's
- Checked all the props were spinning in the right direction
- Checked if the props weren't upside down (letters facing up)
I wasn't able to find what is wrong with it, i did find something that changed since the crash but i'm not sure if it is what makes the quad flip. When plugging in the batter the ESC's beep and all motors sort of uhm.. tick? i guess this has to do with calibrating them on startup. But one of the motors ticks less than it used to. I recorded it and i'll put the video below. The motor i'm talking about is the bottom-left one. the one with the broke prop.
So to make this long story short:
Did i break my motor? Do i need to buy a new motor? Or what else could be wrong?
I hope someone can help me, i'm kinda stuck at the moment, thanks in advance :)
A small question :P i read the receiver antenna's should be in a 90 degree angle. i put my antenna's in a bit of an alternative position i guess by putting one behind my recording camera across the frame. and putting the second one parallel to the fram underneath the battery. This way they are in a 90 degree angle, but probably not in the most optimal position for receiving. Could this be a problem in the future?
