After crash 1 week ago, I decided to modify my QC. It was quite heavy crash. I broke frame and 2 propellers. Problem was that I didn’t see it well.
I weld frame with solder iron. And it is as strong as it was before crash.
I added 2 green blinking leds in a front. I used them because they work on 4 volts and 3 mA. I tried to use led strip. But consuption was about 20 mA per stripe on 12 V.
I connected 1 led per cell. Because I have li-po alarm, I solder them directly on li-po alarm pins. So 1 led gets 4v (1 cell on battery).
Then I made 4 legs from plastic. Because QC frame is too low. And when you put it on a grass it is like a lawn mower. There weight is 75 grams. It was 100 grams, but I drilled holes in legs.
Now it is 11 cm off a ground. And you can attach camera below frame. Very usefull.
