<< How well does it fly with one rotor taken out?

Like a brick. >>

Nah.

That's on all four.

Lose one and it flies like a brick outhouse in a thermal.

Notice the 4 ea engines are interconnected by driveshafts.

I would think that if you lost an engine, you'd simply lose 25% of your power.

If the rotor itself gets whacked, it'll probably still fly better than any helicopter that's lost a rotor.

I think it's PURDY!!
