Hello everyone

The Curtiss f9c sparrowhawk parasite fighter was always for some reason one of my favorite biplanes.Surfing around in the internet I found one kit from Dumas and without further thoughts I bought it.A week later I got a box which had the kit of the F9c and it contained some plastic parts, plans, instructions,but no balsa parts....My fault I was so eager to buy it I did not read the description.....But, I was determined to build it I had the plans and the parts so I blackmailed and bribed my friend Tasos who converted the plan into a file the laser cutter could read and voila.I started building it the worst part being stripping the 1,5 and 2 mm balsa stringers.It will be powered by a CO2 engine.I will use the ABS parts to make a mold for the wheel pants and the cowl.The cockpit will be balsa .

This is a great subject and I look forward to following the build.

Almost done with the half left side cutting the stringers and sanding them to fit tightly was a time consuming work.Then the right side formers will be glued along with the stringers. At the same time I have applied 5 coats of release agent on the vac formed wheel pants and cowling provided by Dumas. I will then produce molds as the parts will be sturdier and lighter.
