Hi Popriv your timing is perfect! And what I mean by that there is perhaps very little out there for .15 glow sized twins or more, but there is a vast selection of cool electrics out there just waiting for small glow multi engine conversion

Kit Bashing is definately the way to go and is what you want anywhere from .10 to .35 sized multiengined airplanes. Once you work out your under wing or over wing tub nacelle's a whole new world opens up.

I have done many multi engine kit bashes and even a few scratch build using those sizes. I love my little Waco Troop glider twin with two OS .15FP's (yes there an experimental twin conversion in full scale) And I have my Fokker F7 tri-motor eighty inch span with three OS .10LA's.

Bathtub nacelles either over or under are very simple and quick to do If you like I could post pics of various tubs and how they are built but only if you like since I,ve been scolded for posting to many pics.
