Nýtt F5J módel frá Vladimir Models (Mini Graphite framleiðandi)

Hvort sem það er hástart eða hang, sjálfknúið eða vindknúið, þá er þetta ágætis staðsetning fyrir það.

[quote]Vladimir (Models) Gavrilko has released a new F5J model called the Plus at 3.7 meter wingspan and around 900 grams. This model was designed by Joe Wurts and it is going to be a game changer for the F5J arena. Lot of this plane is very proprietary in design and all parts will be produced in house. The level of completion will be very high. Barry Kennedy at Kennedy Composites will have one at the Toledo Show to examine. Keep watching as this is just the first of new planes coming from him.[/quote]



[quote]PLUS is a newest 2017 unique project of Joe Wurts + Vladimir’s Model expressly for F5J competition.

PLUS is the F5J without any compromises.

Airfoils and wing planform was optimized according to Reynolds numbers for best thermaling and best wind penetration of ultralight model.
Joe’s Wurts airfoils allow you to use flaps in a wide range from -2 to +7 degrees for achievement maximum climb performance in thermals and minimized decline rate in float condition or speedy upwind flight.
The absence of the propeller in the nose is the main Plus advantage. It is greatly reduces the overall drag of the model and not only improves the wind penetration, but also improves climbing in the thermals. Probably, all the pilots noticed a significant deterioration in the flight characteristics of the electric plane in comparison with the glider (without a propeller in the nose).

Plus F5J has very unique advantages:
+ the best thermaling performance;
+ unique wind penetration performance;
+ low drag without prop spinner and blades in the nose;
+ right direction of rudder moment reaction of opposite V-tail;
+ very easy handling;
+ ultralight weight;
+ compact size for transportation.
