Well then you have no baseline with which to compare ..
Let me put it in even 'plainer' English; I already said that my remarks relate to a 'compatible comparison' irrespective of whether or not the Raider can achieve any specific size.
If for example the Raider's 'constructional limit' it a 10 place aircraft then what I am saying .. is that I believe it will be me more cost-effective to build and maintain the Raider concept than a Tilt-Rotor of comparable size.
As far as actual figures (in terms of cost) are concerned, no one has a clue and nor will they until these concepts are further developed. My sole argument is simply that a comparable size Raider will be more cost-effective than a Tilt-Rotor (and which I do not believe is a startling revelation) and which belief will be borne out by time alone!
