......why not do one of those as well?......
Plea over - Peter
Did I say I/we were not
There are however other priorities ahead of a K3 and whilst they certainly appeal, that appeal is (personally) far surpassed by GEVOs, Br221, Br01 or Br50 on a magnitude that is almost impossible to articulate.....plus about a dozen other engines in my list.
To effective develop a 'commercial' product you have to have a passion and a staggering pile of reference material, in layman's terms I could live without a K3 quite easily and good reference material is hard to come by, especially if your bench mark is the likes of Piercy or MoK.
Sadly big engines sell, even if duplicated several times over; when I did flightsim models, Spitfires, P51's, Fw190 and Me109's just sold and sold, Concorde and B747 too, yet Blenheims, Do17's and Swordfish et al panned.
It'd probably take longer to develop a K3 than say a Princess Royal due to the sheer lack of information, yet the Princess Royal would outsell a K3 five times over. Faced with 500 or so hours of development time it's a brave man who grabs a K3 by the tail as opposed to other sure fire winners, it's a sad fact of business I'm afraid.
