Ichi-go Akitainu 3"

UPDATE: Quad decided to make an unclimbable dead tree with vines and crackling branches as its final resting place. RIP.

UPDATE 2: Might just rebuild this again, but this time with more LEDs and colourful neon props so it will be easier to find. The HGLRCs are a bit too sensitive I believe, so will be looking at other stack alternatives.

This is actually my first quad build. Had a Walkera and a PNP Diatone GT-R90 plus a couple of Whoops but was inspired by Albert Kim's 2s build using the Akitainu frame and decided to go for an ultralight 3" quad with 1408 motors. Looks wise I was inspired by the murdered-out looks of the Furibee Darkmax.

So far it handles great, but I had to soft mount the motors and the whole stack to get rid of vibrations which made the quad drift to the left in angle mode. Flies fine in Horizon and Acro. Also as Albert Kim pointed out in his video the 2.1mm lenses won't fit in this slim frame, go for the 2.3mm instead.

Chose 1408 motors paired with the HGLRC stack powered by a Tattu 4s 650mAh, I think it's a pretty light build with extra punch. Now to see whether it can carry a Gopro or not!

ADDED : Total weight is 135.4g. I thought it was a fluke but I ran a couple of packs of the 4s 650mAh lipos and I'm getting 10+ mins of flight time if I was just hovering (was just testing my drifting problem). I'm assuming I can get at least a good 8+ mins if I was to fly regularly.

Why the いち - ご?

Because it's quad #1 1号

Wow. Great first build... looking for a three inch that has some power to it. This may be my build.
Will mention your @ once i finish it!

Looking forward to your build! Let me know if you have that drift problem as well. I actually ended up soft-mounting the whole stack on double sided foam only and it has held well.

Lookin GOOD! You really cured drift with motor soft mounts?!? My current setup has annoying drift every time I do a pre flight hover in stab mode. I don't think too much of it cause I fly in acro, but I sure would love for it to go away.... Motor soft mounts eh? I always thought that was just for sensitive gyros, but i'm willing to learn something new. I'm on a dys f4 pro, so i'm soft mounted at the stack, and running an mpu 6000 so I wouldn't think it would help... guess I have to try it now!

irmanhilmi   Feb 02, 2018 

I don't think the motor soft mounts solved it, as it was already on when my setup was drifting. I think it was my stack soft mounts. I actually used rubber bushings that came off some parts from my Axial Yeti! But yeah, it solved my problem! Of course I did everything else that you'd see on Youtube though.

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
