STRIX Mk4

UPDATE 6.27.2020

The first TransTek F7 was DOA. The second died after a couple months. I put a Radix in, and tuned it.


UPDATE 3.36.2020
I completely rebuilt this quad from the ground up after the ESC exploded. Now it's rocking Vanover motors, a 45a esc, the runcam racer 2, a rushtank vtx, and a transtek f7. It performs even better than the last iteration and I'm just dying to get some laps in with this quad as soon as quarantine ends!


After a few months of being a freestyle dream, I converted this build into a pure racer. I cut weight where I could, and replaced the motors for some Brother Hobby Speed Shields. By my rough calculations, @ 45 degrees cam tilt and ~60% throttle - this build screams along at 80mph (128 kph).


When I started this build, I was hoping to use it for races....

Funny thing is, I took it to a field for its maiden and I was blown away by it's freestyle capabilities. Been through a few BIG (tree meet drone at 40+ mph) and i've only ever had to replace props.

I like the look and design of that frame (for freestyle). How is it holding up? did you like building it?

mayan_hawk   Nov 25, 2018 

Really well actually. It has taken a couple big hits and everything is intact, including the motor wires. That may be partially due to the tape job I've done on each arm to keep them contained (@charpu). The build itself was fairly easy, there's more room in the frame than I initially thought and I'm thinking of waterproofing it for the winter season.

I like that the "chin" hasn't broken off, it looks awesome with the big holes there and under your boards. It ALSO looks scairy with your gear all exposed, but maybe i'm paranoid? I like the pyrate look of the frame naked too!

Admidittedly the boards get gunked up more often than I'd like. Since I have the motors reversed (figured I'd try something new) I'm constantly having to open the frame up for cleaning

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

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..
