RE: Black Magic v2 builder's thread! *Updated*
Hi Dave,
the rudder has the "stock plans" cord. I did add that curvy piece of balsa in front of the fin. I did trim the trailing edge a bit to thicken, my trailing edges are a little over 3/16" on elevators and rudder. That is a little thicker than the stock cores. You can see the extra piece of balsa at the hinge line of the rudder to maintain the length. I need to double check my length again. But I was about 1/4" short of 2M.
I am thinking I might add a curved piece of carbon lam behind the ducts to wrap the airflow downward along the firewall. The prototype plane that I am flying doesn't have the naca ducts and doesn't seem to have a cooling problem.
Anyhow the naca ducts just look really cool. and I like that fact that Mikes inspiration is from a '85 Z-28. It's fun filling in the ducts with epoxy /microballons. I need to do more sanding and a little more filling on te ducts, but they are looking great.
Well after the thanksgiving holiday, I'll be kicking up a balsa dust storm. Looking forward to getting paint on this beauty.
I guess I will be building two more planes this winter. I have another V2 kit and the Districts kit that I won to build/finish.
