Firefly-YCTTSFM Posted June 6, 2008 Share Posted June 6, 2008 I'm considering using a rotary engine in my OpenEZ project. Like O-320/360's, this is a heavier powerplant than the aircraft was originally designed for & shifts the CG noticeably aft. I've seen references to people putting ballast in the nose to achieve better CG ranges. What do you think about extending the fuselage by 6"? Option 1: Leave a gap between the backseat & firewall. Scoot the pilot, GIB, nose gear, canard, etc forward, leaving the strakes & wing attachments in the same place. Option 2: Leave the GIB seat in place, just increase the separation between him & his instrument panel (wasn't expecting anybody flying from the back seat anyway). Or is it just better to put some ballast into the nose? Thanks, Firefly Quote I don't care, I'm still free. You can't take the sky from me.
