Hey mgnostic, I’m glad you chimed in.
I picked up a 4*60 a couple of years ago off of FB mkt place. The guy was trying to convert it to electric and gave up on it. I picked it up real cheap but it is badly fuel soaked. Trying to dry it out with KR2 & heat with towels but this may be a perfect candidate for a twin conversion. It has a 79 inch wingspan with the added wingtips.
did you design the nacelles yourself or are there plans to do this somewhere?
