5-Inch 4S Build in Progress

what are those motors? 

A new addition to the family! I'm sure it'll take it's first steps (flights) on 4s, then before you know it, he's all grown up and wanting 6s and hanging out with all the other quads getting up to all sorts of mischief, flips, rolls, powerloops. Ah, they grow up so fast....

You’re spot on with that. I have 6s love it. This is just a build I wanted to try. Never ripped a 4s 5”
