We have guys here that run Andy Brown rigger fins on 1/8 scale and Gas thunderboats. I run cut down Accutech scale fins on my sport hydro and rigger. It is only about what works, some work better than others on different hulls. Rule of thumb, a turn fin should be as thin and as strong as possible. We are also using carbon turn fins moulded off an AB fin, which seem to work well, even on gas thunderboats. I will be running one on my 1/8 scale when I get it finished.
