You may want to close off a portion of the front of the cowl to reduce the amount
of airflow getting inside the fuselage and to help direct cooling air into the plastic
ducts. We have done this using clear packing tape as shown in the photo. A
couple of small pieces of Depron would work as well.
27. Install the receiver at the rear of the battery tray using Velcro. Use Velcro to
secure the battery to the battery tray and use a Velcro strap around the battery.
28. Use the supplied nylon bolts to secure the wings to the fuselage.
This concludes the assembly of the Yak-54.
Radio Set-up and flight tips.
CG range for the Yak-54 is from 3.50”- 4.00” from the leading edge of the wing
measured at the wing root. Correct CG should be easy to achieve by moving the
battery along the length of the battery tray. Adjust to fit your flying style.
Control surface recommendations are as follows:
Elevator- 10 degrees low rates, 45+ degrees high rates.
Rudder- 20 degrees low rates, 45+ degrees high rates.
Aileron- 20 degrees low rates, 45+ degrees high rates.
Use exponential function to achieve the best “feel” for your particular flying style. I
highly recommend that you take the time to set up rates for precision flying and
separate rates for 3D. The Yak-54 is capable of flying very precise maneuvers, and
proper rates and CG will allow you to experience this to the fullest extent. Trying to
fly precision aerobatics with 3D rates is an exercise in futility. Spend some time
dialing in and trimming your plane and you will be rewarded with a great flying
experience.
Thanks again for your business!
See you at the flying field!
