Thanks Paul!
Last night, I really suffered a setback. As somebody might learn out of my mistake, I will show You this one.
One of the rear rotor blades of the kit was bend. Hence, I wanted to straighten it.

For this I used the steam of boiling water. The blade was fixed in the straightened position and held in the steam.
The effect was awful. Not even, that the blade twisted in all directions. It even shortened about 10 mm

.
Can anybody tell me what went wrong

? Was the distance to the steam too short? Or is there enhanced stress in the plastic, releaving due to deformation when heat is applied?
As I had no spare parts I had to make a new blade out of sheet material. This was ground to a proper profile.
Sure, the blade of the kit is more convex, but in this scale, it is okay for me. The mounting of the old blade was cut of and glued to the new one. Following is a picture of the three rear blades. Guess which one is the new
