On the quest for the ultimate micro, 4in was something I explored with the Apex initially. Brotherhobby 2004 motors turned out to be trash. one crash could result in multiple broken motors. The selection of 4" T mount props is junk as well. But with the 2Fiddy, a much much lower AUW meant i didn't need super pitchy props.

Talking with @Sub250gFPv i found xnova's 1804 1900kv motors and so I decided to order 4" arms for the 2Fiddy, get some insta360 go 2 mounts printed and build something that could compete with the Babyhawk II HD. How does it fly? Update So I got a buddy of mine to tune it and... it's awesome. I love it. I actually took it with me on a trip and flew it after I crashed my 5in 2Fiddy in the ocean XD.
