Husky 4-Inch Getting Started Guide

A compact FlyFish Atlas 4 cruiser with enough power for light freestyle, built around DJI O4 Wide, 2.4GHz ELRS, M10 GPS and 4S power.

FlyFish Atlas 44S ONLYH743 + 45A AM321804 3500KVO4 WideM10 GPS

Real FPV, not a stabilized DJI camera drone. Never arm indoors or while holding the Husky. Props off for motor, receiver and Betaflight checks.

The build

Frame

FlyFish Atlas 4.

Stack

Flywoo H743 Mini Pro with 45A AM32 ESC.

Motors

HGLRC 1804 3500KV.

Links

DJI/Flywoo O4 Wide, 2.4GHz ELRS and Mini M10 GPS.

4S only

Do not assume a pack is appropriate because the connector fits. Inspect cell count, physical condition and fit. Secure the pack and keep the balance lead away from props.

Prop choices

2-blade

More docile, efficient and relaxed for cruising and learning the aircraft.

4036 tri-blade

More grip and authority for punch-outs, rolls, flips and light freestyle.

Verify the aircraft's configured direction. Do not guess props-in or props-out. With props removed, verify motor rotation; then match every CW/CCW prop and confirm downward thrust.

Startup and first takeoff

RADIO → GOGGLES → HUSKY

4S LiPo healthy and secure
Correct props tight and undamaged
DJI video and OSD clean
ELRS link, ARM, BEEPER and modes verified
GPS given a clear view of the sky
Short controlled hover in a large clear area

GPS, beeper and care

GPS is useful, not magic. Configure and safely test Rescue before depending on it. Learn the FlyFish beeper switch before the quad disappears in grass. After every flight inspect props, motors, hardware, antennas, GPS, camera, TPU, battery, XT60 and visible wiring.

Husky personality: two blades for the distance runner; 4036 tri-blades when those 3500KV legs decide, “watch this.”
