Known for his many great flying, giant scale WW2 warbird designs, Nick Ziroli Sr., has been finishing up his newest set of plans, this one for the WW1 Sopwith Triplane. This sport scale design has a sport airfoil for improved flight performance and is not intended for scale competition.
Using his signature traditional balsa and plywood construction, the Triplane is powered with a Zenoah G-38 gas engine and the finished version will have a 69 inch wingspan.
The Sopwith Triplane is about 1/5-scale (20%), and it performs beautifully. Nick is doing some final tweaks and when it is all worked out, the plans will be available through the Ziroli Plans website, along with many of his other plans and building accessories.

According to Nick, the test flight went off without a hitch! Great flying performance and only need a couple of clicks to elevator trim for hands off flight. The video shows it is well behaved on landings too!
