ASH 26

 

2001-02, ASH 26, 3,6m wing span and use the SD7032 as wing profile, flaps, 3,8 Kg weight.



The ASH 26 fuselage was bought, as usual, by Uwe Gewalt in Reutlingen. The wings are home made using a Styrofoam kernel covered with Abachi. Due to the relative slim profile a diagonal carbon fabric was used to glue the kernel material with the covering wood (torsion). As wing servos I am using the Multiplex FL BB Servos which is about 11 mm size height. Used for the flaps the servos completely build in the wing and there is no step in the surface. This is not the case for the servo used for the aileron, the trailing edges of the servo cover is about 1 mm higher as the wing surface.

The glider reacts heavy on thermals and will circle easy with used flapperons. Due to the gliders weight the glider can be used up to 20 km/hrs wind velocity.

The wing plan was drawn using the free 2D CAD Program Solid Edge (ASW26_Fluegel.pdf).

This model also later received a conversion with Torcman engine. The first records with engine are available from the year 2018. In addition to the Torcman motor, a Graupner +T 70 controller powered by a 4S 2200mAh battery is used. Also an UltraGuard backup battery is used to secure power of the receiver system. This has increased the mass of the model to 3.8kg. In the history evaluation of DataExplorer you can see how much the internal resistance, of the drive battery used over the years, varies. However, this seems to have little effect on the capacity per altitude meter used in climb flight. Nevertheless, the falling voltage ensures that, if the internal resistance of the drive battery is too high, the capacity can be utilized less.
