Dave,

Can you summarise what the requirements of JAR VLR (NPA 2) are?

I am also curious what classifies a machine as a kit, and what the certification requirements for a kit are?

If a machine is not certified what restrictions are imposed? Is it allowed to hover 5' AGL for example?

No - i am not planning to become another low rotor inertia statistic, but i would like to understand the constraints...

Ultimately for the Pegasus i would only comment that i'm suprised that several small gearboxes are seen as such difficult things to develope! Surely a chat with say Gleasons (or the Cranfield Gear design course) would be easier than reinventing pressure jet technology? Besides how is the thing going to be yaw controlled, unless the plan is for a NOTAR type steerable nozzle.
