I will soon start to build a 60 inch Das Ugly Stik Jenson kit that once it is finished I hope to fly in a relaxed manner. After closely examining the plan I have some questions that I hope someone can advise on.

1. Neither the plan nor the instructions show how the engine is fitted to Former F1, or, the recommended distance the prop driver needs to be from the Former. Is it a case of mounting a glass reinforced type engine mount onto F1 in such a position to place the prop driver on the vertical and horizontal centre line of F1, the engine then mounted to give clearance and at a distance that “looks” O.K.

2. There is no recommended movement for the control surfaces.

3. The plan shows the centre of gravity (CG) but the instructions state that the CG can vary dependant on the finished weight of the model. Surely the CG on the plan is the datum.

4. Has anyone got a suggestion on the engine to fit to the Das Ugly Stik and what material to cover the airframe with. I would prefer to fit a 4 stroke engine.

Thanks.
