This is the 1/4 scale Balsa USA Fokker D VII with the MVVS 45cc gasoline engine. Colour scheme is the Rudolph Berthold personal colours of summer 1918. Pilot is Christiaan Geyskens.
Thanks for your comment. A G26 is too small in my opinion. The model takes the power of a 45cc well, and the additional weight is more than welcome (although the MVVS is light for its size).
Although I have put all my gear as much forward as possible (nothing aft of the balance point), and with the MVVS 45cc, I still had to put 0,8 kg of lead in the nose to balance. Total weight ready to fly is now 9,8 kg.
Thank you for answering my question. I will keep that in mind when I build mine. I hope it flies as good as yours. Raul Cardona, CA U.S.

Good knife edge! How does it balance with the 45cc? The manufacture recomends a G26. It takes off with authority. Thanks. Raul
