So! This is technically my second build, I didn't document the first, as I pretty much just copied a (very sick looking) Acrobrat from here on RR (courtesy of TheDronanaut).

That being said, this was a huge improvement, not over the quad itself, but in my ability to build it; both efficiently and for longevity. That is, she's already taken some gnarly crashes.

Without further ado, I present to you, "Roy G. Biv".

The HelioRC Spring IMUF v2 was incredibly easy for a beginner like myself. Clear instructions (though many of the documents and pics refer to v1, mind that, there are differences.)

A great thing about the Spring FC being paired with the Holybro Tekk 4-1, is that the 8(?)-pin connecter between the two is completely matched. No modifying the layout, no added soldering, etc. Additionally, the pads on the Holybro 4-1 are HUGE, nearly too big. But better too large than too small, right?

You will notice that I used rubberized standoffs and rubber grommets on the FC, hopefully that is a non-issue.

So far, everything is holding up exceptionally well. My only real gripe with the build (and this one is on me) is how I oriented the power wires coming off the FC. Other than that, I'm lovin' it.

Side note: I very much enjoy the building aspect, if you see anywhere in this build where I could have made some improvements, please do tell! I love learning and I want my kwads to survive the many crashes that they will see, inevitably.

Beut of a kwad. One thing I noticed was the XT60 solder joints look a little cold. Very clean stack tho. Kudos!

hey thanks for the kind words!

the xt60 to FC joints are by far the most difficult for me. I still haven't sorted out a great way to do them.

thanks for the reply, just received them in the mail and love the look, I building a light weight racer with them so I hope they do good, also want to use the 20x20 helio with the 20x20 aikon coming out.

FWIW, this fc/4-1 combo is the easiest setup I've ever experienced.

that's good to know, I've also never used butterflight but it seems really similar to betaflight

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..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
