Cinewhoop Builder
Cinewhoops are the safest way to fly FPV near people, products and walls. JoinFPV's cinewhoop builder helps you balance payload (a GoPro Hero 11 + ND filter weighs more than you think), motor torque and prop pitch so the duct doesn't choke airflow at hover. We also validate that your TPU camera mount won't intersect the prop arc — a mistake every new cinewhoop builder makes once.

Frequently asked questions
Can a cinewhoop carry a full-size GoPro?
Yes — most modern 3.5-inch cinewhoops handle a Hero 11/12 (~150 g) on a 4S 850 mAh pack with 4-5 minute flight times. JoinFPV warns you when payload + battery exceeds your motor thrust budget.
Why are ducted props quieter and safer?
The duct shrouds the blade tip, eliminating the slap noise and protecting people and walls during low-altitude indoor flight.
