4” Hex Racer

After a bit of drinking at IO this year I somehow convinced my good friend Truc Quach of Kinetic Aerial Designs to design me a 4" hex racer. We saw a lot of interesting and innovative designs in the X Class race and it inspired us to go wild. He came up with this 4mm thick plate that takes Merica pods and keeps all the motors in a row rather than a traditional hex. We went this direction because I think it looks cool and somehow it flies fantastic. I ran a 58.3 on the global qualifier the day after I finished the build. My best with a conventional quad was a 56.7 for reference. Second one is coming soon with some 1606 motors and a few other small changes, this thing has ruined quads for me.

I phrased that poorly: the flying is FPV, the footage is LOS. I can hover without my goggles on and that's about it!

No footage yet, I'll grab some DVR at my next race. Maybe some LOS too, got a few compliments about how rad the "6 pack" looked in the air

FANTASTIC! You used a Matek F411! I may need to ask you a few Q's.... I have a 2.5 hex OTW (and I am gonna use F411 too) and only this minute received a 7" (https://rotorbuilds.com/build/19781)! Thanks for sharing!

Honestly the F411 could not have been easier to use. Pad 5 and 6 are already mapped as DSHOT outputs so solder up your signal wires and choose the hex mixer. Thats literally it. It was running away into the sky on BF4.0.5 but flew fantastic on stock 3.5.7 so I'd probably start there. That 7" looks like it's going to be an absolute hoot with big props and 6 big motors!

That is great news (that the F411 is as straightforward as one might hope)! I love it for anything smaller than 5 inches because it is really a great FC. 3.5.7 is my religion... I just got a dual gyro F7 and didnt know it required 4+. This one (7" ARX-R) seems to be doing better than my past experiences... but we shall see. I am nowhere near as confident in it as I am the 7" hex.

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..
