Somebody mentioned an electric hydraulic pump?
I would prefer one driven off the main txmsn. Works better after an engine / electrics failure, you don't want to be like the old B47s where an engine failure also meant hydraulics off.
With the fore/aft collective, which way is power? Pulling back, sort of like pulling up, or pushing forward like a throttle in a jet? Some muscle retraining needed I reckon. The video refers to the target buyer as somebody with a lot of money but unlikely to fly more than 50 hours a year. Does anybody think that a private pilot in a performance machine like this, flying an hour a week, will not join the statistics in a shortish time?
