Thank you! I'm glad you liked the Instructable. This is good fun to fly in places where you wouldn't be able to fly a bigger racing quadcopter. However, it definitely feels a good bit slower than 210 size racers, despite my attempts to make it as fast as possible. I noticed this when I moved the electronics from the ZMR250 to a smaller, lighter frame, and now it makes the 130 feel slow.

Thank you! I am not aware of anyone using 3D printed propellers, as they would be pretty hard to get them right and they would be very fragile. I bought a few of the DAL T3045, DAL T3045BN and RotorX 3040T propellers and all of them work well with these motors. The RotorX are the most efficient but are also the most expensive and are less durable than DAL.

Thanks! I'm glad you liked it.

Thank you!

Thanks. This quad cost me about 250$ (USD). I already had some parts such as the radio transmitter, FPV goggles and video receiver. Those are generally the most expensive parts to buy (though you only have to buy them once) so if you don't have them already it will cost a good bit more. There aren't too many substitutions for cheaper parts you can make with this build as parts this small generally come around the same price point.
