All:
- They usually don't have a receiver integrated.
- If they have a ESCs or current sensor (big mag fields), they probably don't have a mag.
Revo class have everything except OSD, ESCs and current/voltage sensor if you can use the 433 RF for control.
Omnibus F4 (in a dev branch of code) has current / voltage sensor, and OSD, but no mag, receiver, or ESCs
So what about FPV Tx, OSD, mags, current, voltage, GPS ?
