I followed TweetFPV tutorial to build my own budget gates to train myself, have fun regardless of the outdoor temperature/weather and keep my cat active!
In fact, I found myself flying whoops (65mm to 85mm) more and more often due to the lack of adequate space to use 4/5 inches.
Totally amazing your skill level is fantastic and bravery 5***** , 
Please tell, is the footage speeded up, or do you have reactions ten times as fast as the rest of us ?
Check the timer on the top left 
It’s just matter of confidence, and a lot of crashed. BTW, it’s not the fastest tiny whoop I do fly: this one has got 19kv motors, I now fly 25kv
