Tiny Whoops

Tiny whoops are the gateway drug of FPV. These palm-sized, ducted drones weigh under 30 grams and can fly safely indoors without destroying furniture, pets, or relationships.

What is a Tiny Whoop?

A tiny whoop is a small ducted quadcopter, typically 65mm or 75mm motor-to-motor, with integrated prop guards that also function as aerodynamic ducts. The ducts increase thrust efficiency and protect the propellers from impacts.

The original “Tiny Whoop” was a Blade Inductrix fitted with an FPV camera — the name stuck and became the generic term for all small ducted FPV quads.

Why Fly Whoops?

• Indoor flying: Fly year-round regardless of weather
• Low risk: Light enough that crashes don’t break things (usually)
• Cheap: Complete setups under $100 for the drone
• Quiet: Won’t bother neighbors
• Skill building: Tight spaces force precision flying
• Social: Whoop races are common at meetups and events
• No registration required: Under 250g (well under), no FAA registration needed in the US

Components

Frame

Whoop frames are injection-molded plastic (or carbon fiber for performance builds) with integrated ducts. Common sizes:

• 65mm: Standard indoor whoop, 31mm props
• 75mm: Slightly larger, more power, still indoor-friendly, 40mm props
• 85mm: Pushes the “indoor safe” boundary, but more capable outdoors

Motors

Tiny brushless motors, typically:

• 0603 or 0702 for 65mm (1S)
• 0802 for 65mm-75mm (1S-2S)
• 1102 or 1202 for 75mm (2S)
• 1303 for 85mm (2S)

KV ratings are high (10,000-25,000 KV) because the batteries are low voltage (1S = 3.7V-4.2V).

Flight Controller + ESC

Most whoops use an AIO (all-in-one) board that combines the flight controller and 4 ESCs on a single PCB. Common form factors:

• 25.5x25.5mm mounting
• 20x20mm on some newer designs

Popular boards: BetaFPV F4 AIO, Happymodel CrazyBee, JHEMCU GHF411AIO.

FPV Camera + VTX

Usually a tiny AIO camera/VTX combo. Runs on the same board voltage. Some use analog, some digital (Walksnail 1S, DJI O3 on heavier builds).

Battery

• 1S (3.7V): Standard for 65mm whoops. 300-450mAh. Flight time: 3-5 minutes.
• 2S (7.4V): More power for 75mm+. 300-550mAh. Flight time: 3-6 minutes.

Connector types: BT2.0 (BetaFPV), PH2.0 (older, more resistance), GNB27 (Happymodel/GNB).

BT2.0 and GNB27 have lower resistance than PH2.0, meaning more power to the motors. If buying new, go with BT2.0 or GNB27.

Propellers

Tiny 2 or 3-blade props:

• 31mm for 65mm frames
• 40mm for 75mm frames

They wear out fast from crashes — buy in bulk (packs of 16-32).

Setup Tips

Betaflight Settings for Whoops

• Motor Protocol: Usually DShot300 (some older AIOs need DShot150)
• Idle percentage: Raise slightly (5-6%) to prevent desync at low throttle
• Rates: Lower than a 5” quad — tight spaces need precision, not speed
• Filters: Stock filters are usually fine. Don’t over-filter on whoops.

Battery Tips

• Don’t over-discharge — whoops are light and the batteries are tiny, so voltage sag is harsh
• Storage charge batteries you won’t use within a day or two
• Buy lots of batteries — you’ll go through 6-10 in a session easily

Indoor Flying Tips

• Remove obstacles: Lamps, glasses, pets — clear the flight path
• Start in a big room: Living room or garage before attempting hallways
• Fly low at first: Ceiling fans and light fixtures are whoop killers
• Turtle mode: Set up “flip over after crash” — you’ll use it constantly
• Prop guards work: Bouncing off walls is normal and expected
