Yea, you can use the wooden blade but u hv to make sure the head speed is below 2500 rpm, but I won't take the risk though, now a carbon / fibraglass blade is not expansive that much less cost than the total loss of a heli. Not to mention when u / someone get hurted due to the accident.
I am just a new player, so select wooden, if just for normal flight and hoving purpose, is that wood OK, because I previous play King 2 , already damage 8 pair wooden blades ready, so i now upgrade to play 250se.
Yea, you can adjust the head speed as you like, say not to exceed 2500rpm, but 250 is not suitable for beginners ,it is more unstable and tricky in setting up especially on the tail. Why not get a bigger one like 450 or go even more bigger these heli is more stable than 250 and cost the same (i mean compare to 450).
