Lightweight 2s Freestyle quad.
Top-mounted Lipo for that true freestyle feeling.

*I designed this frame myself, and after months of R&D, I've decided to market it. It's called the "JunkYard" because you can put just about anything on it. Click link to frame to learn more.

If only the frame were deadcat layout. Would be perfect🙁....I hate the props in view of the cam feed.

Deadcat bottom plate is now available!

This design is a prototype but, based on the successful stretch frame.
The top plate (https://armattanproductions.com/pages/product_details/23693) is universal to this JunkYard series.

I have ordered this frame myself to begin demo's, I would welcome any input or comments!!!

Thanks! suggestions: there should be a 3mm bottom plate option; also, not sure if I missed it, but there's no weight in your description (dry weight of the assembled frame).

I I can create a version with a 3 mm bottom plate and also 2 mm top.  I used those sizes when I was prototyping these frames, but in the early stages I was struggling with the power to weight ratio. When I trimmed them down to the current sizes, I hit the target AUW.  I really beat these things up on a regular basis and so far I haven't broken any frames. The reason I didn't put dry weight of the assembled frame It's because there are a lot of different configurations that can be used (with or without the camera mounts, or ignoring the top plate if you choose to use 3-in props). I have all the individual weights of The frame pieces separately. were you looking for those weights here on rotor builds or on the frame order website?

When I refer to the "Micro" or "Micro-brushless" class, I'm broadly referring to quadcopters that wouldn't annoy people if you took it to your local park for a fly while there are kids on the playground, heheh. To me it's an evolution of the "Toothpick" class. I loved the Toothpick (hail Kabab), but I wanted something with more "heft" to give the 5" freestyle/racing feeling.

Thanks. Bob did not invent the toothpick.

I dont believe he did, but I do believe he perfected it (just my opinion though).

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..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
