Shendrones Squirt v2

I was browsing RotorBuilds one night and stumbled upon rtyler's insanely clean Squirt v2 build. I couldn't get it out of my head and knew I had to build one.

I copied Nurks PIDs from his blog and they work great. Based on a few things I had read I was prepared to have a bit of a hard time flying it in a cinematic way but it wasn't that bad. I definitely need to slow down my pans so the horizon doesn't tilt so much. I'm considering trying RealSteady GO for horizon lock, I just need to print a new GoPro mount that isolates from vibration better, as there are issues with the Hero7 and RealSteady if you have any vibrations reaching the camera.

The maiden flight video below was filmed at dusk last week so the lighting isn't the greatest. I've got some ND filters I'm excited to try out on a nice sunny day though, hopefully soon. I love this thing and can't wait to get more footage this summer.

I almost forgot - the TPU ducts. I have an Ender3 3D printer and it's pretty dialed in for TPU. I figured these ducts would be no problem at all to print and I'd save $55 vs buying the pre-printed ducts. Up until this project my TPU prints had all been pretty small - battery holders and canopies for whoops basically. These ducts are huge and even with retractions turned down as far as I could reasonably set them, I had 5 or 6 prints fail at about 90% (8 hours into printing) leaving me with a bunch of nearly finished ducts to throw away. I eventually tried a slightly harder TPU from Amazon - Priline Black in 98a shore hardness. It produced a perfect set of ducts on the first try. They are nice and soft but not so soft that they deform at the slightest touch. I also printed the GoPro mount and the antenna mount (designed by rtyler, see link below) in the same TPU and they came out great as well. The GoPro mount could probably stand to be printed at 99% for the Hero7 Black, it's a bit loose, forcing me to run a velcro strap around the camera.

I know these are quad blade but I jave switched them

How hot are they? Most people say as long as you can leave your fingers on them for 2 seconds without getting burned you're ok.

If they're seriously too hot to touch you may want to search around for filtering and PID tips for hot motors.

THanks yeah I have never had motors that felt like this before thats why I freaked. Ill do some more testing. I think Ill flash Nurks BF version and go from there. Thanks again Bootbox!!

Hey Bootbox how are you liking your Shendrones Squirt V2. I just bought the frame, but will be printing my own parts. Also wanted to ask I see everyone is using 5mm hub motors and was thinking of going w/ Emax RS1408 1.5MM shaft so I would not have to cut props any thoughts on this and thanks sir.

Yeah buddy of mine might be building one now lol. I have a 550 hexacopter I was using for aerial video, but this is whay smaller and cooler.

I was really suprised how locked in it flies. It's super stable even in acro mode. I think it has to do partly with the design and partly with Nurk's PIDs. He has the I-term pretty high and the D-terms relaxed. It wouldn't be a very good setting for a freestyle quad, it's really stiff. But it's perfect for the Squirt.

Im really super excited about this build and enjoyed your video. Look forward in tuning it. Id like to see what Plazma Tree says with those pids

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
