We are the first manufacturer who is offering real 10 mm (0.39") sized wingservos designed to be used exclusively in wings and rudders that are using the latest narrow profiles. 

In the case of a 10 mm servo using conventional technique, it would be necessary to use smaller components. 

Accordingly a smaller motor would provide an inferior performance and a smaller potentiometer would give limited reliability. 

As neither would suit our intensions we decided to think about a new way to build such servo:  

Recesses like small windows within the new housing allow the biggest components such as motor, potentiometer and gears to get to the same level as the outer shape of the housing (see photo on right side).  

Using this new technology we manage to use the well proven motors and potentiometer of our Micro-Star 3 and Micro-Maxx servos. 

The newly developed gear train using only four instead of five gears, reaches almost same gear ratio as Micro-Star/-Maxx. 

Changing from five to four gears minimizes backlash and increases efficiency, with the result that the new 10 mm servos have even greater performance than our Micro-Star 3 and Micro-Maxx servos! 

The high tooth flanks of the new gear train and the glass reinforced housings make our new Wing-Star and Wing-Maxx servos very robust servos which are completely Made in Germany. 

As you can imagine we do not supply our Wing-Servos with an open housing: thin stickers of only 0,08 mm strength cover mentioned recesses without measurable increase of the thickness. 

The mounting system of our new servos is a completely new design: lockings tabs and corresponding slots on housing and frame let the servo snap into the frame putting it into proper positio (see photo above and photo underneath). Using 2 mm screws the servo is fixed afterwards.
  Mounting Instructions 

We have applied for patents for the new case design as well as for the new mounting system. 

The 10 mm thickness make it possible to use our Wing-Servos directly in the control surfaces of sailplanes, big scale gliders, electroflight and engine powered models or jets. 

Wing-Star and Wing-Maxx have a ballbearing on the all metal gear set on which we offer a 5-Years-Warranty. 

Both servos have the same housing and the same high-class potentiometer (with 4 wipers) but use different motors and different amplifiers. 

The size of the complete system including the frame is only 29,7 x 48,6 x 10 mm, the weight is 19 g (23 g including frame and screws). 

We supply these servos complete with mounting frame, servoarms, screws, aerodynamically shaped covers, instruction sheet and VMS-microconnectorsystem with an adapter of your choice. 

Additionally we supply precut plywood strips for reinforcing the recess within wing (see photo above) or rudder.
