Hi Ted, et. al.

Do you know if the V8 configuration of the Thielert will fit in the cowl of existing Lancairs?  So far, my discussions with DeltaHawk (also a "V" configuration) and SMA, (opposed flat) seem to indicate that there is no direct drop in replacement for the powerplants we are looking at.  The C182 I test flew at Oshkosh this year was an excellent test BUT...they had to add another airintake below the standard scoops because the diesels run hotter (at least theirs does).  The Delta Hawk engine also looked promising with a planned 300 HP version envisioned but their "V" heads would insure that the lovely lines of the Lancair's would suddenly develop some bulges.  I would really have to do some serious thinking on the butchering of those works of art before I would do that kind of mod!  And being as the SMA was air cooled but the Delta Hawk and Thielert's are water cooled, the need for more air (and the big scoop) could be a moot point but what about you engine wizards?  Any thoughts on whether all air cooled and/or water cooled diesels will require big, ugly air scoops added?

Another question in particular to the ES and most especially the Super ES builders, when completed, are they prone to being nose heavy, tail heavy or pretty much right on?  And have any builders had to ballast the tail?  That could be another serious consideration.
