2" 2S babyshark: ready to crash

Built a 1S tinyshark and then immediately wanted a lightweight 2S for more acro power.

This guy is lots of fun. He crashes well. I think the prop guards help save the not-super-robest racerstar motors from a fair bit of trauma. Though it does feel more agile without the guards.

Cons: I really don't like the micro cmos camera, and the version of the cam i have extends past the canopy by quite a bit unfortunately. I've shifted focus with a frontal crash already. Using an unsightly glob of hot glue as a bumper at the moment. I shelled out for the runcam nano hoping for better video - waiting for that to arrive, not sure if it'll fit the canopy.

Thinking about using the fullspeed baby16 2S stack in this guy (losing telemetry, gaining OSD) and moving the 1S-2S capable tinyfish+star6+pololu stack to the tinyshark, to make it 2S-capable.

PIDs that work:
roll: 30, 40, 27
pitch: 40, 50, 32
yaw: 70, 45
4k/4k, dynamic filtering, PT1, both gyro notches off

TODO

  • replace tinyfish + racerstar + pololu stack w/ fullspeed baby16 FC+ESC and micro frsky rx. Loses telemetry, but gains OSD. Becomes 2S only.
  • try runcam nano for better light handling, low light?
  • design new pod with more camera protection. maybe that can fit AIO cams.

The FSD-tx200 seems to fit pretty tight. do you have problems with overheating?

deks   May 25, 2018 

Yeah, it was tight but I don't think I had issues with heat. Though I've since redone this build to use a custom pod: https://rotorbuilds.com/build/11346 (i need to finish the write-up, so it's still a mockup at the moment)

That pod is designed for use with a micro AIO whoop-style cam+vtx, like the cm/vm275t or the LST-S2 Shinehalo camera, because I found that those cameras actually had better image quality than the cheap banggood camera that the babyshark pod is designed around. You do lose the ability to do 200mw, though.

Wow that pod looks awesome!

I love how it gained prop gaurds only after you rammed it into yourself 😂and the squirrel was so chill about it

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

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..
