Questions the plans left open to interpretation.

I'll happily add anyone else's questions to this. The answers will be covered in later posts.

The plans never mention the weight of the prototype: What do these things really weigh?

The plans indicate the prototype used a Rotax 277 and that it was underpowered: What defines underpowered?

The plans indicate the Rotax 447 is the recommended motor, it weighs 82lbs. The plans state the motor weight budget is 80lbs: What is the real engine weight budget?

The plans don't have any indication of what the target weights are for components: What should each part weigh?
