I hope all goes well on the test stand.

I remember looking at the one Frank Taylor had in Chino many years ago. The construction seems quite simple. I suspect the lack of engines is really the problem. Maybe something like a DB601a could be substituted, but those are probably all earmarked for German aircraft restorations which are likely more popular.marine air wrote:These KI-61 airframes have been around since the 1970's and no one has made much progress. I belief is that there is a "story" as to why they haven't been completed. Are there no blueprints? Was the metallurgy in wartime Japan faulty and can't be trusted? It's almost like there's a technological hurdle of some kind preventing these from being rebuilt.

I would think with the given success of the Erickson HA.1112 being converted to use an Allision engine, all the while retaining the original look of the German BF109, that a similar process could be applied to these KI-61s. Making them turn-key much cheaper / easier to maintain aircraft instead of more difficult, demanding, and specialized regarding the DBs.
