A collection of my personal mods for the amazing AtomRC Penguin!
---
### Features
- Multi Purpose Canopy
- Integrated air intake for cooling VTX & pan servo for sightseeing.
- Mountings for pitot tube! Use default version if you do not want to mount airspeed sensor.
- Elevated base for using oversized battery; I was able to fit 10800mAh battery.
- Reserve bay for user customizations. Experiment with your own payloads!
- Back Cover Multi
- Able to mount Insta360 ONE RS, using standard hand-screw for selfie stick, for recording acrobatic FPV sessions.
- Air intakes for cooling avionics.
- Optional mounting position for telemetry modules such as MicoAir LR900-P.

### Tips
- For mounting Insta360 ONE RS, IT IS ASSUMED THAT ONE WOULD USE HIGH CAPACITY BATTERY (>5000mAh). Check CG after installation.
- Unfortunately, I could not fit 4S2P 21700 LiIon pack... Maybe 4S2P 18650 would fit?
- For long range cruise session, I found DJI O4 Pro overheats when using 4K 120FPS record settings. Just keep that setting for high speed acrobatic sessions!
- The camera housing (O4 Pro version) is identical and compatible with [my Super Drift mod](https://www.thingiverse.com/thing:7005008). This Penguin mod is actually the original one to use such housing design, predating around half a year.

### Reference Performance
- Cruise speed: 20m/s (~70km/h(A))
- Max Speed: 60m/s (~210km/h) (45 deg. dive)
- Landing speed: 11m/s (~40km/h, with half flaperon(B))
- Cruise range / Endurance: 70km / 1.1 hour (10% battery margin(C))
(A): I deliberately use high cruise throttle setting to punch through west wind. For maximum endurance, target 14m/s (~50km/h) cruise speed.
(B): Due to airframe having ailerons situated back far from CG, I found flaperon to be little use other than air-braking.
(C): The record is without Insta360 One RS mounted.
