Coming soon: Happymodel Larva X 100mm

Happymodel Larva X 100mm FPV drone

Happymodel is planning to release a new small-sized FPV drone called Larva X100. As its name says, it adopts a true-X frame with a 100mm wheelbase. The Happymodel Larva X quadcopter is 2.5″ propeller compatible and can be powered by 2s~3s LIPO batteries. The aircraft weighs about 50 grams without a battery.

Thanks to the versatile Crazybee F4 Pro V3 flight controller, you can configure the Happymodel Larva X 100mm with multiple flight modes (Angle, Horizon, and Acro). According to your existing transmitter, you can opt for a built-in DSM2/DSMX, FlySky, FrSky D8, or TBS Crossfire radio receiver.
