The Yak-11 was designed as an advanced trainer for use by the Soviet Air Force and came into service in 1947. The pilot and instructor sat in tandem under a long canopy that had separate sliding hoods. Although designed as a trainer, Yak-11s were also used in combat during the Korean War, and more recently, highly modified ones have been used very successfully for air racing. The Steadfast was built from scratch as an out-and-out high-performance single-seat racer in Romania in the early 2000s. It was based on the Yak-3, but essentially it looks the same as a Yak-11, so our model is based on our previous Yak-11 model.
The inspiration for our Steadfast version came from Nick DeCarlis (MrSmoothie on RCG), Nick had converted the original Yak-11 into a Steadfast version. He made his own single-seat canopy and changed the color scheme to give his Yak-11 a striking new look. HobbyKing regularly works in partnership with members of the RC community to develop new models that not only look great but are also well-proven and tested when it comes to their flight characteristics. So, we would like to give thanks to Nick for all his help and assistance in developing this version of the Yak.
The H-King Yak Steadfast is supplied with a power train that has been developed for pure speed. Using a 6S LiPo pack, the 5020-550KV brushless motor with the supplied 95A ESC and 16x6 prop will give it an incredible turn of speed of over 100 mph. It is very quick, and seeing a model of this impressive size doing fast pylon turns near the ground is a sight to behold. Aerobatics are also a dream to perform, the rolls are very axial, and looping maneuvers are big due to the abundance of power. The only limitations to the aerobatics it will perform are your flying skills.
The model is full of outstanding features, these include CNC machined fully functioning oleo struts, servoless retracts, split flaps, LED landing lights, and navigational lights. It is supplied as "Plug N Fly" with the motor, ESC, and high-power metal geared servos factory installed. Building the Steadfast Yak is also very quick and straightforward due to the minimal parts count and preassembled components. The fit of the parts and the finish of the Steadfast Yak have also been improved over previous versions of this model.
The striking H-King Yak Steadfast is an impressive 1450mm wingspan scale RC plane that has impeccable handling characteristics, has plenty of power, and looks stunning in the air. It is a must-have addition to any RC modeler's hangar and will turn heads when flown at your local model flying patch.
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.
Powerful Propulsion
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.
Landing Gear Fit For Field Landings
This military trainer has pre-installed and very robust electronic landing gear with proportions true to scale. Thanks to the 80mm sponge rubber wheels, not only does the YAK-11 perform well on hard runways but also on grass surfaces during take-offs and landings. On the ground, the aircraft can be maneuvered into the correct position with its movable tail wheel.
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.
Authentic Visual Design
This model offers numerous scale details and exact proportions. In addition it has visually authentic rivets and panel lines, mock exhaust pipes and a painted pilot figurine. However it is not only the appearance of the model but also the flight performance, with the characteristic Yaklovlev wing geometry, that makes the the model a smaller yet in all other ways equal counterpart to the original.
Quick Assembly
Through the built-in electronics and the high degree of prefabrication, this model aircraft can be assembled in less than 30 minutes.
