Birdbrain RC Hoverfly 2.5

Had a spare 20x20 Mamba stack, an rx, and a VTX, and figured I might as well throw it all in something - ordered a set of Mamba 1105 motors, 2.5" and 3" props, and a Runcam Robin, and sat down to design a frame to hold it all.

Was thinking about a little race quad, but then decided I'd like to try to create a really tiny GoPro hauler, complete with guarded props. Original design used ducts like my Goshawk, but I couldn't get a clean print and realised at the size I was working with I might be better off with a lighter weight milled HDPE guard. Top plate is drilled with an absolute ton of holes for mounting stuff to - also considering a top plate fitted with a load of M3 press nuts to make accessorising easier.

Build was a challenge - the Mamba FC has a long row of tiny pads to solder to, took some delicate work. Since the wires for the VTX and camera go through the top plate, they had to be soldered to the FC in place attached to the top plate and 3D printed mount, a little awkward.

Wasn't trying to hit any particular weight (and designed this to mainly run on 4S), but it comes in at 245g with GoPro and a 450mAh 3S lipo - good result!

any chance I can buy this frame? I checked your website but it's listed as out of stock

you should do it upside down with the batterie and everything on top

awesome design but yes I agree - turning it into a pusher quad might make it even better!

dude you need to sell this frame, I would buy!

looks super cool, considering on manufacturing em?

I'm planning on it! Honestly, been planning to sell frames for literally months, at the moment I'm away racing almost every weekend though which makes progress slow! Certainly by autumn I'd expect to have my webshop up and running :)

Thats a really nice looking cinewhoop, and I bet it'll deliver better footage than all those split type cameras. I never could quite consider something like on of those board cams to be "cinematic."

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..
