F4 boards are only and spread since one year only and now F7 board are already in the corner: https://www.banggood.com/Omnibus-F7-V2-Flight-Controller-STM32-F745-MCU-2-4S-Built-in-Betaflight-OSD-Dual-Gyro-30_5x30_5mm-p-1215667.html
Not only CPU clock are one more time increased versus the F4 but now a dual 6-axis IMU is present to improve even more the stabilization’s performances. More, the gyro-accelero chips are installed on a dampening gel and should absorb any vibrations transmitted by motors. The F7 board is large (36mmx36mm) and weigths 10g so clearly for >130mm machines. With this board, no problem to push the machine up to 32Khz.
OMNIBUS F7 V2 now with inertial damping gyro jacket. The case mass absorbs & resists by inertial damping the vibrations coming from the motors, props, frame, ect… – The added crash protection. The case is mounted by Gell tape and not hard mounted to the airframe in the same way a normal gyro is isolated. In our testing this does work better then soft mounting the whole Flight Controller.
