Helio Spring V2 IMU-F F4 Flight Controller FC
Improvements over V1
No more jumpers! Simplicity is our motto.
Inductor is on top to account for faulty ESCs emitting substantial EMI.
LC filter on the OSD line
Filtered camera power.
New orange color!
Truly Freeing
Supported by multiple open source flight controller software including ButterFlight’s 3.3+ most current technologies
Natively Fast
True 32khz processing without overclocking
IMU-F
Never before seen IMU-f system an advanced inline discrete filtered gyro that is transparent to the flight controller. With a super clean discrete filtered gyro, more processing power is available for flight controller logic and future feature updates without causing slowdown or issues during flight
Helio Gyro
The hardware contains both an f3 (IMU-F) and an f4. The gyro is a IMU 20601.
