4" Raven Split

I've always been fascinated with the Split cameras. I really like their image quality for how compact they are, but definitely do feel some of the latency they add. It's not a huge amount, but I notice I'm slightly miscalculating turns and such. For this build anyway I've decided to deal with that.

The frame is my own design - pod stl can be downloaded here - This variant was made to fit boards with the USB placement of the TBS Podracer AIO, and Foxeer Micro Lollipop vtx antenna. Carbon is 3mm, with a 1.5mm battery plate attached to the stack screws. To secure the battery I'm using wide rubber bands which I don't think would work well with quads any bigger than this, but seems pretty sturdy here. Whatever type of strap is used, I very much prefer to have two of them. Otherwise there's not much to say about it.. it's a carbon fiber X with 4" arms and whoop board mounting!

Behind the ND filter is a Split 3 Nano Whoop. I'd love to replace it with the newer Split 4 but couldn't find them in stock domestically. One thing I've seen somewhere is that the Split 4 can lock ISO, which I'd think would make the filter more useful. For that reason, on the Split 3 I'm not sure if it's doing anything at all but after a few more flights I'll find out.

We're having some crappy weather in my area, so I'll try to post some footage once it clears up and I figure out a good tune.

Initial flight impressions:
This thing can cruise for an eternity. Using the 850mah 3S pack pictured, I flew for 14:30 at low speed.
Tuning is coming along with pretty high P & D values, which I recall being key for similar 3" builds on 2S. Not quite where I want it to be yet but getting there. Will have video soon.

Would you like to share the print settings for the canopy? Usually when printing these kind of canopies they they look awful due to the amount of supports required to print it.

All in all a really clean and good looking build.

Thank you! I'm printing on a MP Maker Select with Flexion extruder, Sainsmart TPU, and using Raise3D's ideaMaker slicer. Basics are 1.5mm layer height, 100% infill, and support set for angles above 60deg - I usually add auto supports and then edit them manually for better results. You can adjust the number of vertical layers between support/model, and support density to get a cleaner release. Hope that helps!

I'm not sure if you have a spare UART for an Openlager but this would be a great rig to stabilize with Gyroflow or ReelSteady Go.

The Van   Apr 17, 2021 

No spare UART but I suppose that's something I could use softserial for right? Anyway, stabilizers would move the frame around and I'm not a huge fan of that with props in view. Just hoping I can get a jello-free tune :)

When I see stuff like Gyroflow and RellSteady, I wonder what happened to Plasmatree... ?

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..
