I had a OS50 in mine which was more than adequate also I had no weight issues with a light weight silencer but feel I would have with a standard one, I think going up to a 60 may cause a cofg problem, unless you put the tail servos at the rear which is an option of course.

As to the wing hole if you go the route of patching under the surface do fill the void with a lightweight filler as the edges will show through otherwise, then don't forgett to laterally balance the wing afterwards.

The only way to learn how to cover is to do it, but some and try, Wings are the easist to cover, do the bottom first and then the top, if you can attach the ailerons after covering both the wing and the ailerons, tip sections are easier if you cover them in seperate pieces the curves are difficult but possible with a bit of paitence and using a seperate piece you can have more than one go without ruining the main panel. The most difficult bit on a wing is getting a straight edge along the leading edge with different colours top and bottom, you can buy a trimming tool to run along the le that makes it easier, if you are not confident get one.

Cheap film covering is just that and is more difficult to use than good stuff like Profilm, Whatever you do use a new sharp blade at all times to cut the film, good stuff is tough.

Good luck
