Armattan Gecko performance build. No measures where taken to make this build lightweight -- chasing grams using Armattan's Gecko frame would be the wrong choice anyway.

iFlight Xing 1408 3600KV together with Aikon 35A V2 4in1 ESC equipped with metal heat spreader deliver robust performance.
This ESC can only mount sideways in the Gecko frame, otherwise the discharge pads won't have room. It's not too bad after all -- motor cable routing came up quite clean.

Front stack features RunCam split DVR, TBS Unify Pro32 VTX mounted on the 20x20 stack mount together with the RX.
The remaining amount of free space between cam and front stack is used to squeeze in the Vifly Finder 2 buzzer.

This results in a solid dry weight of 180g. No, this build will never be even close to sub 250g...

With T3056C props this Gecko flies 4+ m even with a 4s 650mAh, 850mAh are obviously a better fit. Everything stays cool -- F4 flight controller, ESC and motors. Sound is quite aggressive, some 5" are more subtle.

Nice! Thats how a Gecko should be - stuffed. I think they fly better with the extra weight. Mine is similar and flies like a 5”. Harder to tune but tons of fun.

BF 4.2 with RPM filtering runs already quite OK with stock PIDs. Roll tracks really fine, pitch has some minor bounce back -- expected this due to the asymmetry along the axes . The Aikon FC has logging, so this will ease the tune.
It won't become a jello free cine whoop for sure, especially not with a RC Split. But hell yeah, it's really so much fun to fly this beast.

BF 4.2 with RPM was a huge improvement for mine. I dont have logging so unfortunately i haven't been able to use that to tune out all the shakes. Still one of my favorites.

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..
