Realalistically a .60 size airplane should weigh no more then 8 lbs for good performance.
Not really. Maybe in a 3D plane.
Look at the 60-size GP Seawind that weighs 10 - 12lbs. The plane flies great!
People tend to think that their is only one type of flying and that all pilots like the same thing.
Let's look at Warbirds: The Japanese had the Zero, which could out-fly any fighter the Allies had. But the Allies could drop a Zero like a bug with a single hit.
Why? Because they had no armor - they were built to be light and agile, not to be shot at. So while they may have flown better, they did not accomplish what they were designed to do.
You've never heard a P-51 pilot say, "You can't add wing tanks to that plane, it would be too heavy"
Now, granted, you need to fly a P-51 differently if you've got wing tanks on board, and it's the same with any plane that you have added weight to. But that's not to say that adding some sheeting to the wing will cause the plane to perform poorly.
In this case, the OP is talking about a GP Extra 300 60.
I had this plane and I built it as per the instructions and for me, it was too light. If I had to do it all over again, I wouldn't hesitate to sheet the wings
