Sounds sweet. I build my Echo I with 18mm mounts. Much more subdued in flight

If FSI motors magically reappeared on the market, I think I'd go for the 21mm motors but stay away from the 27mm E and F motors. There are just too many composite motor options out there now that would be less prone to CATOs.
