Now that I have a good idea how this Cub flies at 17.5 pounds (wet) it was time for some accurate CG placement. I had added a 9oz weight in the compartment that is just behind the fire wall when the 26cc engine was up front. Now that the 35cc engine is up front the Cub flew pretty nose heavy. Power off glide slope was horrible and roll / yaw axis stability was poor. That weight is now gone and the Cub is now balanced perfectly at 3.5" from the wing LE. The Cub now weighs 16 pounds 7oz dry.
I got back to the cowl for some more filling / sanding and the two large cracks and large hole (for old spark plug) along with the rough splintered cowl areas are now gone. Some primer and light sanding is in order next.
Looked over the engine for irregularities and found nothing
. Nice pretty and shiny as when it came out of the box. Muffler nice and secure and bolts still nice and snug.
