Thanks for the interest in this post. I'm not going to make a removable hatch, but not a bad idea. The next step before i start is lay-out the plans and make any modifications you want to do on the plans.
My modifications will be:
1. Clip one wing bay each side-Draw in new hinge areas. I'll use Robart Hinges on this project.
2. Add 1" to the Rudder and Elev. Draw on the plan
3. I'll Cowl the front using a "Fiberglass Specialties" Cowl. Clip the cheeks front of fuse.
4. Add several aftermarket products replacing the kit supplied products.
