The Yakovlev Yak-11 was constructed in 1944 by Alexander Yakovlev, specifically for the advanced flight training of fighter pilots. At that time, Yaklovlev was able to pull from his experience with the extremely successful single-seat fighter series, the Yak-1, 7, 9 and 3, and apply the advantages of these aircrafts to the Yak 1. Finally, he combined all of that with a radial engine.
The two-seat aircraft was used by all member states in the Warsaw Pact as well as in the Middle East, Austria and China. The wingspan of this military machine, which was primarily manufactured in Czechoslovakia, came to 9.4 meters and it was propelled through the air by an air-cooled 7 cylinder radial motor with 700 hp.
Light and Stable Construction
This model is constructed out of EPO hard foam material, which is not only very light but also incredibly robust. Minor damages can be quickly and easily repaired with superglue.
A high powered brushless motor is built into Staufenbiel’s YAK-11. The motor consists of a KV 410 external rotor motor and a Hobbywing 80A regulator with an 5A UBEC and it is powered by a 6S battery. In combination with an APC propeller this model boasts a powerful flight and a noteworthy climbing performance. As a result this model still remains stable in the air.
Large Split Flaps
In order to reduce the approach speed for landing, the YAK-11 has pre-fitted and installed split flaps that enable highly controlled landings.
Through the built-in electronics and the high degree of prefabrication, this model aircraft can be assembled in less than 30 minutes.
