Scratch-Built 75mm Tiny Whoop

Built using this video as a guide. Buy the batteries that use the BT 2.0 connectors, either that or use ones with XT30 connectors and replace the one on the flight controller board. Reason being, the PH 2.0 connectors, even though they are more common, are not as good for tranferring the amperage, the connectors are just too small, so you'll end up getting voltage sag.

These parts are small

It's great to be able to fly inside when the weather is bad outdoors. Of course, it won't handle high winds, but it still can handle moderate ones. I noticed indoors that the camera was quite sensitive to low light, so decided to try it at night using just the streetlights. I was really surprised to discover it is extremely capable of flying at night, you can see from the video how well it works. Incredible considering the camera is so small and cheap. Also I was surprised as to the range, I was able to go all the way to the end of the block with a really good video signal.

Small but mighty

Also, one of the comments in the description gave some better PID tuning values, which I can confirm work pretty well. It's a bit hard to read, so I've made a screenshot from Betaflight showing the configuration values.

A note on the videos: this is recorded from the FPV goggles, obviously this thing is too small to hold a separate camera. As such, the footage is analog, so if you have any epilepsy or seizure issues when seeing flashing images, do not watch the videos. The analog signal causes flashes and color changes constantly. Probably doesn't need to be stated, but if you get motion sick easily, do not watch these.
