Stop 'praying to you Tali H500 each flight by adding LED's above the ESC and have them visible from above.
DO AT YOUR OWN RISK. Use care as errors during modifications can kill your Tali
For less than a couple of dollars you can have the convenience.
Avoid going over 20mA with the LED. Talk to your electronic supplier and ask for LED and resistor combination for a 5 volt system.
My video shows the brightness of standard LED's. The better the LED the brighter the light.
