G'day Which Taube are you building? I built the smaller of the two BUSA versions. I have only flown it twice as it was quite a challenge to fly. If you are building the larger version with ailerons it may fly better.

The real Taube used wing warping for roll control and the elevator was not hinged but warped up and down too. Without some form of wing input into rolls, the smaller model Taube will only turn with LOTS of rudder. I found I had to hold the rudder through the whole of a turn. This is not normally the case with rudder/elevator planes - holding the elevator once the turn is started is usually enough but not for the Taube.

The engine bay is rather small so I used a Saito 40 which worked well.

I really should put the engine back in mine and have another go at flying it but the engine is currently in a nice little 80% size Astrohog which flies perfectly.

Perhaps I should build the larger version?
