Don't know about him, but I'll likely do the HeS 011 powered versions
(including engine, which I intend to market) with at least the swept
back wing+butterfly tail. I'd like to find data on the proposed "B"
model, with larger wing and fuselage stretch, powered by either the Jumo
004 or HeS 011. The later swept wing versions would have had the same
stretched fuselage, and the alternate wings were obvious, but on the
increased size straight wings, there is next to nothing available.
Depending on how well it is done, the kit engine might need replacing,
and the engine done for the Craftworks kit would be good replacement. I
don't know when, or even if, now, the Craftworks '162 will ever happen,
but the engine at least ought to be useful.
