Yeah, ive read that befor "fluttering" but a guy on youtube "bankheadrc" did a video of his DRXL to show it. I then built mine with epp and had the fluttering affect too. Balsa is more stable for me and i trust it more for my setup. Side by side balsa is way stronger. Epp elevons are good but for light loads.
