Hi,
Not sure where you are up to with the Elliptical Anthem. I haven’t flown the SB version but have had two trimming flights on the Anthem E. it looks and feels great. Very little mixing with CofG at the recommended point. This was a monoprop version using an R210 outrunner and 21x 12 prop. Motor aligned to the nose ring. Vertical up perfect, vertical down slight pull to canopy, which can be fixed with throttle to elevator mix, though may yet be dealt with by moving cg further back slightly. Rolls really well, very Epilogue like in its character.
Not sure if I’ll ever get another go with it but definitely recommend this for any level of pilot.
Thanks
Keith
