Hi, I am very new to this and would love to hear from everyone's experience on this hobby my experience was so awesome until one day I crashed it into a tree and all went south from there. However, I have managed to do a shell replacement by myself thanks to the Internet. Everything is perfect now except for a broken camera gimbal and one LED light underneath one arm is not litting. Unfortunately, the unit is fine after the test flight (about 3 time). I suspect it might be a bad ESC I am having in one arm or is it just the LED? I did all preflights check with GPS signal on, I can't see how many satellites available as The camera gimbal unit was broken and I am flying it without the camera gimbal. However, I did wait for a good 5 minutes before flights now to make sure it acquires enough GPS lol. I inspect the ESC in that particular arm but no burned IC or loose connection on that ESC. The unit is flying perfect with stable hovering so I am wondering what is the real problem Right mow I am still saving for a new camera gimbal unit. Please advise me on ehat I could do wiht this problem. Thanks heaps guys !!!
