Fun and DESTRUCTION (2)

Wow does time (and my tiny whoop) fly. I have had a great week of flying my QX90 inside and outside. I have brought it with me whenever I go out, as you can see from some of my videos post which take place at my Uncles house. Crashing has been a pretty common occurrence for me. I have broken more than 20 of my 3D printed prop guards. Luckily, they cost less than a penny each to print. I also have broken 6 propellers (costing a whole $0.15 each). I hoped this would be the extent of the damage but unfortunately that is not the case. On Monday, I flew with a battery that was too low for flying and was unable to complete a punch-out as planned. Because of the resulting voltage drop stemming from sudden amp draw on the already depleted battery, the craft could not complete the banked turn I tried to do and started to oscillate about 35 degrees from its axis until it flipped and hit the ground. This picture shows why rapidly moving above 35 degrees on such a small aircraft is so problematic. Instead of being felt by passengers like the picture says, it was applied to the opposite end of the aircraft as well as the FC, which is MUCH more problematic.


The impact knocked the lens and CMOS assembly off of my FPV camera. Unfortunately, this is not something that can be easily fixed. I ended up having to buy a new camera  and replace the existing one I soldered the replacement unit into the lowpass-filtered section of my F3 Evo flight control board and it works! I was only out of the air for 3 days, but if felts like forever.


Here is a video of the crash. When the video goes white, that is when the camera fell apart, yet the TX still transmitted video (impressive!)

  1. ^^ those videos were stunning :D in actuality, that sucks that your camera broke! Luckily there is Amazon Prime lol. For robotics, we always test our batteries before using them.. looks like you should do that too :D. You should try to fix up that camera and use it as a backup in case anything goes wrong with this one in the future.

    1. Thanks for the suggestion. I have now made it a policy to test all batteries with a multi-meter before using them. As for the camera, it is beyond repair. The CMOS sensor itself was damaged and the lens shattered. If I break my current camera, I will unfortunately need to buy another. Lets hope it doesn't happen!

  2. You should've used more power-ups

    1. Your absolutely right! I will be sure to hit the in-air performance boosters next time. /s

      In all seriousness, their are some "power-ups" that I can use to improve the performance of my quad. Look at my week 3 blog post for more information on that.
