Saw this one with a stock Fuji 50cc at a recent fun fly. Pilot flew aerobatics with it very well but didn't do any 3D. Not all of us care for 3D, anyhow.

Mine will have a Fuji 50cc with CH Synchrospark. Direct mount onto the firewall gives exactly 7" as called for in the manual - no standoffs or spacers necessary. Great for easy setup.

Fuji will have a new version with electronic ignition out pretty soon, which you can pick up at around $450 easily (480 - $30 discount). Not a bad deal.
