Crux3 - great for all flying levels!!

Great little thing that is responsive and fun to fly, not super hard for beginners and super nimble for experienced flyers too!

Great quad

I got this thing to reenter the fpv quad world. I've been really enjoying the flights. It's fast on 2S but not out of control. Highly recommend.

capable little 1s,

indoor and outdoor, both capable.

ESC died after 10 flights

The drone flies great and is very efficient (7 minutes of freestyle on a 450 2s). The electronics are quite exposed so I recommend not flying it in wet conditions or conformal coating. They really should provide some mechanism to hold the antennas in place without getting chopped up by the propeller. I got the FrSky SPI receiver and the range is quite bad, it will fall out of the sky with no warning at random when flying just 60 feet away line of sight with no obstructions. Highly recommend getting a dedicated receiver and orienting the antennas appropriately. Unfortunately one of the ESCs died after 10 flights - I did not turtle mode or block the props in anyway. Got a replacement AIO controller board for $50 to give it another shot. I choose this option so I would not have to solder/assemble but I now have to solder on a receiver and repair the drone so I can't say its a durable drone and ended up costing me as much as a higher quality, more durable quad like a diatone or iFlight which I should have gotten instead.
