Looking into building this kit, but finsim is showing fin flutter at some relatively slow speeds for a 98mm powered rocket. Tip to tip reinforcing is obvious, but I'd expect even that has its limits.
Flutter speeds by method:
U vs G: 166 fps
SQR(X) vs 1/k: 337 fps
Quasi static (main display): 830 fps
It wouldn't take much to exceed these speeds. With a 98mm motor it might be a challenge to stay under these speed.
Who's flown this successfully? What motors/speeds? How did you handle this?
