Karearea Talon SVX220

NZ frame Karearea (predatory bird from NZ) Talon SVX220.

I made another frame that was designed to be light and aerodynamically slippery which was great in a straight line but was an unruly mess in the corners as it wanted to drift constantly making it hard to fly with any consistency. At first I thought it might be the underslung battery design, but my WarpHelix frame didn't exhibit this behaviour, it felt far more neutral and I came to wondering if the fairings were aiding it the corners preventing it drifting outwards as that also is an underslung battery design; so when this popped up I figured I would give a vertical armed frame a test run to test the theory some more.

I haven't had much flight time with this yet unfortunately as the past few weeks mates and I have been flying acrobatics through trees (this really isn't the frame for that sort of flying) rather than setting up a track; what I have flown however have shown that this frame feels very 'direct'. You point it in the direction you want to go, and it goes. I believe having some verticality to the arms seems to produce some latitudinal drag, rather than drift outward it seems to bite into the air. It takes some adjusting to get used to as you usually fly expecting to counter some drift but this frame seems to really dig in through corners like it's on rails.

Not the lightest of frames compared to the some of the more anaemic frames out there right now, but building a frame with vertical arms requires very fine tolerances and some inventive ways to get the arms to mounts to the body so an ultralight weight vertical armed frame seems a tall order. However, this came in at 306g using not insignificant sized motors (2207) with heavy props (Dal Cyclone 5050) and full size camera. A change in props and a Micro camera will easily get under 300g which is hardly a heavy quad.

Kudos goes to Karearea for this design; excellent tolerances, strong materials and a really nice feeling quad over all. For track work, I don't think I would go back to something without some verticality in the arms. The Talon is razer sharp in corners while my WarpHelix build is less direct but very neutral; both feel great around a track but I feel like the Talon in the right hands would be a real weapon.

Is this the one with the high / low side plates? Looks really neat btw.

Low plates, 2 stack.

3 stack sits flatter across the top but no real need for this configuration

do you think there might be a freestyle drone with vertical arms? im kind of interested in the idea but not too huge on racers

Karearea is doing one right now, in prototype but plenty of pictures. Its essentially a Talon with slightly different arms and the center stack allows for top or bottom mount of battery.

I think its the KEA35

If you're on facebook check out karearea drone or goto their website I believe the freestyle version is up there too.

The ThinkTank FPV Airport Helipak is the premier travel bag for FPV enthusiasts. I've taken this bag across the country and around the world, and I really can't imagine a better pack for the job. It's huge. It's the size of a carry-on luggage, and it's designed specifically for FPV. It offers customizable compartments that can store a handful of quads, a transmitter or two, a couple sets of goggles, batteries, tools, props and a laptop. If you're feeling lazy you can even pack a couple quads without removing the props. You'll never find yourself saying, "I wish my bag was bigger." Build Quality This is a nice bag. It offers enough padding to securely carry all your FPV gear. The exterior padding is quite thick and rigid. I feel safe packing my goggles and transmitter without any additional keep reading..

The EV100 Micro AV Recorder is a DVR for the Eachine EV100 headset. Eachine should have built this into the headset, but here we are. It's about the size of a matchbook and works quite well despite a short learning curve. It's powered by the same battery included with the EV100 and uses the white balance lead. Other than that you can use either of the included 2.5mm to 3.5mm cables to plug it into the video input/output port of the EV100. You can either strap it beside the battery in the headstrap or use the included double sided tape to mount it to the top of the goggles. Vs the Eachine ProDVR This is obviously a repurposed Eachine ProDVR, but it does simplify the design. The ProDVR has different pins for each input and output. In fact the entire side of the unit is dedicated to various keep reading..
