Spoiler servo installation

The spoiler servo is to be installed using a strip of double-sided foam tape (not supplied in the kit) to the W28 balsa sheeting. First, apply thinned epoxy or thin cyano to the inner surface of the W28 sheeting in order to be sure the double-sided foam tape will stick. Reinforce the inner surface of the W22 and W23 airbrakes in the same manner.
Epoxy the W33 magnets into the holes in W22 and W23 airbrakes and W29 holders on the airbrake frames. Please check the polarity of the magnets first – they must attract each other. (Fig. 30) (Fig. 31)
Refer to the Det. C on the building plan during the final airbrake servo installation. Link the servo horn and the W36 torsion bar lever with two ball links joined together with an M2 threaded rod (saw off the head of the supplied M2×10 mm screw).
Once you check the servo can move freely within the required range, cyano the W36 lever to the W37 carbon torsion bar. (Fig. 39)
With your radio on, set the airbrake servo to the "airbrake fully extended" position. One at a time set the W22 and W23 airbrakes in the fully extended position (-24 mm), push the corresponding lever W35 to the airbrake and secure with a small drop of cyano to the W37 torsion bar. Take care the position of both airbrakes is exactly the same! Once satisfied, secure the joints of W35 and W36 levers with the W37 torsion bar using a sparse amount of epoxy.
Finally, cut an opening into the W25 hatch to allow free movement of the airbrake servo arm (if necessary) and secure it to the W32 holders. (Fig. 40)
