I'll cover the open sections and glass the wing. I did this on my 72" span CMP Zero.

The covering was already wrinkling and coming off in my shop. I don't want to deal with that.

The question is always, " doesn't glassing add weight" , it could if you weigh it. But not enough to cause flight problems if done properly. I plan on reducing the number of servos in the wing by connecting all the flaps to one strong servo and one for the slats.

What do you think you'll do when your covering comes off?
