Lightweight 2s Freestyle quad.
Top-mounted Lipo for that true freestyle feeling.
Dry weight: 60.1g
AUW (350Mah): 87g
AUW (450Mah): 90.4g
FPV footage: Coming soon!

*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.

Frame looks great. It doesn't fit 3" props, does it?

If you can wait just a few days, I will provide a store link. I'm updating all junkyard models to V2, which includes additional battery strap and rubber band locations, as well as extending the camera mount location. In this model, the camera is a VERY tight fit when using a toothpick AIO board.

Sure I can wait. Looking forward to it.

Frame is ready!

Notable changes:
(1) Bottom Plate carbon fiber thickness increased to 3mm for higher durability.
(2) Frame now has chamfered edges for cleaner look and slight weight reduction.
(3) Motor mounting pattern is now 9mm/12mm combo, meaning it can carry a wide range of motors (1103 thru 18XX)

This design was extended to all frame types:

After a lot of research ive ordered the deadcat junkyard and i really think its one of the best 2.5 frame dedins around. Heres hoping for high quality carbon fibre and fast work by armattan productions! i will be flying it inverted with a toothpick fc, 1106 3800kv motors and an insta go mounted.

Awesome. Unfortunately Armattan Productions is never fast (in my experience), and COVID is going to make it take longer. But I have gotten good quality carbon fiber cuts. I really hope your deadcat build shapes up the way you want. I would love to get some pics if it when you finish, maybe send me a link to your build log here on rotorbuilds when you get it done.

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).

tlamb1234   Jun 06, 2020 

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?

Like your build!
what KV did you go with? 10.000kv?

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).

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
