2Fiddy 4" with Insta360 go 2 on 6s

By ExplodingEvo on Sep 05, 2021

4 452 2

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.

Nice build! I just built a 2fiddy 4" on 6s as well. It's a blast. I used the Tmotor 2004-3000kv with a 33% throttle cut. I'm loving 4" on 6s. Also have a 5" 2fiddy on 6s, and love it as well.

I thought about going 2004 but these provide a great amount of thrust and less weight overall. my dry weight without the insta360 mount or cam is 159g. Not as low as my babyhawk but about 21g less than the 5in. I like it but I need to put a cam back in the babyhawk to see which is better.

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
