Also, the flaps.....
As with all the Junkers aircraft, the flaps can be linked to the elevator pitch. This action means you can control the flaps via the elevator pitch control. With the Ju52 it gives it fantastic STOL capability as you can change the flaps angle by single degrees using the pitch wheel and chug along very slowly whilst descending.
Ju87 and Ju88 have only 3 positions...raised, take off and landing but again are automatically selected considering the aircraft speed if linked to the elevator pitch.
Ju88 - Take off - Start with elevator pitch neutral ie. 0 degrees. Select flaps down button once, this activates the flaps and links them to the elevator pitch. Then apply positive elevator pitch until you get 'take off' flaps. To raise the flaps, select the flaps up button to disengage the flaps from the elevator trim. Select neutral elevator trim and the flaps will raise.
Landing - activate the flaps. Use the elevator pitch as above to select landing setting.
Note though, you can't use the elevator pitch to adjust approach whilst the flaps/elevator pitch controls are linked and airspeed will determine what flap setting you get ie. too fast and the landing configuration won't be applied.
Hope this helps
