I am just wondering if anyone has any idea of how a circuit breaker or fuse could be implemented into an fpv plane with rvosd. Maybe in the line from battery to current sensor? I am just thinking that if I go down and lose rc then my eflite motor wil be toast from the prop trying to turn on the dirt or in a tree.
Circuit breaker in case of crash.

Some smart ESCs shut down if the motor is blocked. Check out this wipe out. Plane hit fence and motor stalled so ESC shut it down

I use the K-force series from HobbyKing(Re-branded Hobbywing ESC). It does shut motor OFF if prop get stuck.
However I never crashed while flying FPV, the only time I landed away from home was due to battery going empty. I did set cruise and glide throttle to zero preventing this from happening.
I recovered it next day with no damage other than puffed batteries.

Well, now that you mention it, I remember a crash.
I forgot to configure RC link detection properly(was testing a new firmware) and it was being triggered on full throttle. So on take off RTH was triggered and autopilot raised the plane wanting to turn back to home, but it was too low and there was a building on the path. So I toke manual control back while speed was too low. My inputs weren't as smooth as the autopilot and plane stalled, it was more like a forced landing with landing gear still down.
Lost one of the wheels, and had to change the servoless landing gear retract on one side.

RTH is also helpful if you lose video, which is more likely than losing RC. I have never needed RTH for RC loss, but have relied on it many times during TV service interruptions.

I used the 100, 150 and 120HV versions. All worked flawless. I plan to keep using them on all my projects.
