I could get about the same distance with a Thrasher as I could with a Tern. The Tern is very slightly faster, but the Thrasher glides a bit better. Stability-wise they're very similar. Both will flip in headwinds or if you get too aggressive with torque.
My sentiments exactly with Tern lil faster Thrasher bit more glidey.
I'll eventually have to get another Thrasher. My one sample was much closer to a Renegade than a Tern.
I hear you. I have small sample size too (1 each) and my Thrasher is more understable than my Star Tern but the comparisons and other comments make me want to try another, maybe max weight Thrasher.
