Just curious Tony on all the scale planes you scratch build what is the aerofoil you use and why.

This was a BUSA kit so I used the ribs provided in the kit, airfoil is a flat bottom Clark Y type and is 13 1/2% thick. The Tri Paced has a similar airfoil. Not flying aerobatics so the flat bottom provides plenty of lift at low speeds. The Champ has a NACA 4412 airfoil, it is slightly under cambered and the same airfoil is used on the full scale. The Cherokee has a NACA 2415 at the root and 2412 at the tip. I made the airfoil thicker at root to accommodate the wing tube. The 2412 airfoil was used by Miles Reed on a few of his designs and it works well on our models. I normally stick with what is shown on the plans.

Ok thanks for the info just wandering. The NACA 2412 I know just looking at wing designs and wondered what you were using.

Assembling the interior, the front seat will remain out until the fuel system and ignition are installed.

Outstanding!!

Beautiful job really well done. Just do not know how you have the patience to do all that detailed work.

Very nice!

I haven’t decided yet on flying, but it’s likely I’ll be judging

Bill, How did the event go?
