Pit's Torque (exposed reverse stack build)

The concept is based on my "Scorp" build. The arms and the bottom plate design is largely similar.
The idea came to me when I opened the DALRC Rocket 50A ESC box. I didn't want to hide this beautiful metal cooler below the electonics stack. So I thought what if I place it on the top? I only needed to figure out the top plate(s) so "The Rocket" gets all the glory it deserves. In addition, I couldn't really use a tiny 20 awg wire on the build as exposed as this. The Blue 16 awg seemed to be the best alternative (however about +10 grams in weight).
The build with the heavy DalRC Rocket, 16 awg wires and those Lumenier Zip 2407 monsters is about 320g. Not light, by todays standards, but it surely can make a use of all the power that the batteries can give.

Here is what to do if you'd like to build a quad with this naked style frame.
a) Buy a 5inch, a 5/6 hybrid or a 6inch carbon parts from the armattanproductions here: https://armattanproductions.com/pages/shop_product_grid/3488
b) Buy the metal parts from anywhere you like. (banggood, aliexpress etc..). The complete list of those parts are available in the description of the armattan link.
c) Print the tpu parts yourself or let some friend print them for you. The models for those parts are available for free here: https://www.thingiverse.com/KrisMin/collections/pits-torque

The frame has a 4mm bottom and top plates (30.5x30.5 bolt pattern support only). The arms are 6x9mm in cross section. The body is built like a tank. In case of heavy impact, the arms will give up first. The bottom of the frame is flat - no sticking out bolt heads. The frame is designed to be simple. The arms fit on every corner(mirror). The top plates fit on both sides (mirror). The electronic stack features the shifting plate, same as on "The Scorp". It's a good way to do tight builds and an efective use of the space between the stack and the camera.

With what did you tie three cables near FC? It looks like copper shaved cables.
Thank you for info. :)

Check out the Torque frame Thingiverse collection link at the description. Those in picture are the wire clamps. Printed from TPU.

The description is now updated and the carbon parts are available at armattanproductions.

awesome. Looks like a Hotrod

Yeah the frame definitely shows it off! But fyi, the fc normally goes on top because thats where the least amount of vibes will be, if she's flying funky or hot motors I'd recommend you try switching them.

There is no issue there. Because of the shifted stack design, the FC has double vibration isolation. In addition, the motors and motor bolts have tpu dampers, the motor bolt holes are oversized to minimize direct contact with the arms.

A builder after my own heart lol

Frame shows off ESC nicely. Awesome work!

Any racers 6S really. I am using CHL 1050 currently, but those are not that good.

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..
