I'm not entirely sure yet, because I don't have the plans to study. I thought about motor access, and I'll likely lay up my own fiberglass cowling so that I can remove it and have unrestricted access to the motor. I can also put some NACA inlet ducts in the cowling for motor cooling. I'll see about where the battery hatch goes. Depends on where the battery needs to be to get the CG right. It's a pretty simple airplane so I'm not expecting any insurmountable obstacles.
