fastened in the wing halves. The steering linkage is attached with a double elbow on 
the servo lever; see photo. To mark the length of the steering linkage, it must be 
attached to the lever in the landing flap. For this purpose, a threaded bush is 
soldered onto the end of the linkage and fitted with an M2 nut and an M2 clevis. 
 

 
 
 
 
 
 
 
 
 

 
 
 
 
 
 
 
 
 
When marking the length of the linkage, move the servo to the retracted position. For 
this purpose, briefly turn on the RC system. Attach the linkage in the servo lever and 
adhere the servo. 
If the servos are adhered in the recesses, they must first be fitted in shrink hose. The 
shrink hose must be roughened prior to adhering. 
The servo covers are fastened in the recesses with the accompanying countersunk 
sheet metal screws. Pre-drill Ø 1.5 mm holes in the covers and lower the screws in 
the covers accordingly. 
 
After the adhesive hardens, the landing flap covers are adjusted and adhered. In 
doing so, make sure that there is a gap of approx. 0.5 mm 
the entire way around. The covers should be secured with an adhesive strip to 
prevent slipping and to assure a flush fit with the profile contour until the adhesive 
hardens. Now move the landing flap out, remove the upper brake plate and cover the 
wood with adhesive film. 
Before adhering the torsion pins in the root ribs, insert the two wing halves into the 
hull using the wing connector in order to check the fit.
