congrats on the PPL! we understand that 500k is a high price point for a lot of people (but still cheaper than a new SR20 and we have the same performance and better fuel economy), but our goal is to get to a scale where our 3rd model costs <$100k.

1. the flight controller is triply redundant, so it's basically 3 flight controllers and any 2 can fail and the system will still function (though with a greater risk posture as you now don't know if that 3rd one is giving correct information. There's also an emergency reversionary mode to fly the airplane directly without the flight controller in the loop

2. We don't think that a direct override is necessary or even recommended. We're relying on the fact that we have multiple sensors, flight computers, and servos to make sure that the probability of being wrong is < 1e-7. You can't force a spin in the system and the system will always leave enough buffer so that external factors can't initiate a spin. but if one happens, spin recovery is automatic.

3. We are exploring this possibility. If you are genuinely interested, fill out the contact form on our website and we'll talk.

4. Thanks! we are actively debating making this a standalone radio product for any airplane to replace an existing comm radio
