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?

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.

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

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..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
