I am getting ready to build my dust. Knowing the speed involved and concerns about flutter, I am worried about the elevons fluttering. I'm sure they will be fairly rigid near the horn but I'm more concerned about out near the tips. Has this been a problem for anyone? I thought about glassing the elevons with light glass cloth before covering to give better torsional strength. Is this going overboard?
Power will be a Rossi 45 rear exhaust with full pipe.

you can have your horns further out than normal if you cut serov holes in the centre ribs and have the horns pointing out at the tips, then the horns are outborad of the fins giving more leverage over the whole elevon. mind are 3/32 balsa and dont flutter
