Spline sand the surface, then layout an open bay pattern leaving around 1.5" ribs aft of the spar and cut out your bays.

Re: How to lighten foam core wings??
Can this be done with the sheeting on? I've only seen that done with the foam only... Sorry for all the questions just don't want to ruin a good flying bird

Yes, but not practical at your point of construction. Read through this thread, it may help you understand. http://www.flyinggiants.com/forums/f...-new-post.html

Re: How to lighten foam core wings??
i was just looking at something extra to do when i recover my plane. I've read your threads.. I was just wondering if there was something i could do since the wing was built already.

Re: How to lighten foam core wings??
Well I’ve been doing this hobby for 10 years and I find it just best to leave the wings alone. Take the weight off in other places. I’ve had some wings fail because I’ve tried to make them lighter. It’s just my 2 cents. Hate to see a nice plane go.
Good luck to you!!!! |
