Ken, it is all balsa except for the turtle deck and fin leading edge. Those are wrapped in 1/32 ply. The canopy was laid up using my Symphony canopy as a male mold and lastly the cowl started out as a Vanquish part that will be hacked up and drastically changed but gave me a good starting point. The hatch will be carved out of pink foam. When I am happy with it,I will move onto the wings and tail. Prior to glassing and finishing the plug I will be able to do a complete mock up. Lots of work ahead but I am very excited about the project.
