Orange_ RC_ pilot Here is a little food for thought when you first start learning the skills in using the covering films any brand:

Covering flat open bays such as the bottom of a wing, piece of cake.

Covering a mildly curved surface with a single bend such as a wing top, just slightly tougher.

Covering a sharper curved surface with a single bend such as a circular shaped fuselage, much tougher but with practice?

Covering a surface with a double compound curve such as a spinner, well not for mere mortals.
