Mine has a DA-50 with 2 1/2" standoffs, Pitts style muffler and ever a True Turn spinner... It has #2 2300mah A123 packs mounted as far forward as possible in the fuse, right behind the firewall... I didn't build mine, but bought it from a guy in Louisiana who built it, flew it 4 times, didn't like it and sold it here on RCU... When I got it RTF, the CG was 4 1/2" behind the wing tube... Even after adding a pound to the nose the CG is still 2 1/2" behind the tube... I can fly it there... Love the airplane... Not sure, but if you guys are getting them to balance without removing tail weight, then the fella that built mine must have used cement instead of CA when building the tail...
