High response micro heli from Walkera

The Walkera HM4G3DB2801 4G3 V3 packs double brushless motors and reinforced metal parts into a compact chassis for nimble 3D flying. Its design focuses on direct control feel and component durability while staying small enough for indoor flights.

Efficient power for tight sessions

Using single-cell LiPo technology, the 4G3 V3 balances power and weight so pilots can get multiple practice flights from a single battery. Flight times are typically around 7 to 8 minutes depending on how aggressively you fly, which supports frequent short training sessions.

Electronics tuned for control

The WK-2801 8-channel transmitter comes with the heli to provide clear input and trimming options. Built-in gyro stabilization plus a 10A-L speed controller give consistent responses for aerobatics and stable hovering, suitable for both indoor halls and calm outdoor spots.

The Walkera 4G3 V3 is aimed at pilots who want sharp handling and dependable electronics in a pocketable rotorcraft. It is a good match for focused practice and advanced 3D routines.

Inspect blades and linkages for wear, check screw tightness, and confirm the battery connector and wiring are secure before storage.
Yes, the ESCs and motors are serviceable. Use compatible 10A controllers and matching motor parts to keep performance consistent.
Basic mixes and endpoint adjustments are useful. The WK-2801 supports trims and rate changes that let you tune stick response for 3D flying.
Stick with the supplied 3.7V 400mAh pack for balance of weight and runtime, or try a tested equivalent cell with similar voltage and connector for marginally longer sessions.
Due to its light weight, it is best flown outdoors only in calm conditions. Wind will quickly affect handling, so choose sheltered spots if flying outside.
