We are very happy to introduce F3P biplane Citrino.
This is design of my friends from South Africa. In first steps in F3P class, biplanes were extremely popular. With two wings wing area was big and besides this biplanes create big drag (that was helpful in order to slow down the plane). They were perfectly suited for heavy equipment and simple sequences. Once everyone start to evolve and try to build lighter planes an use lighter equipment, monoplane concept seams to be logical solution.
However return of biplane was just matter of time. With today knowledge and light equipment, very advanced biplane can be very good choice for F3P competitions starting from basic class to insane FAI sequences. Our friends from South Africa show that Citrino is very capable biplane, by putting solid flights in first world championship in Coburg, Germany.
Citrino released by Donatas Design, is slightly bigger compared to prototype. Wingspan is 80 cm , Fuselage 96 cm. Quite big wing area will allow you to use different equipment from slightly heavier and cheaper options, to lowest weight F3P marvels like Lantsov coaxial system and Hitec 5035 servos to achieve best results. Model will fly very well if it’s ready to fly weight will be in range of 90-120 grams. Perfect battery for optimum flight time and weight ratio will be 2S 160 mAh.
This plane is inspired by F3A legend Mr. Wolfgang Matt from Liechtenstein and his latest F3A biplane Citrin. Mr. Matt allow us to release small brother of Citrin, so special thanks goes to Liechtenstein!!!
