I would say turn fins . , Mine tends to spin out but that can always be adjusted by turning the d/r down . I will be putting in a team orion method R 17x2 with adjustable timing motor and we'll see how she runs . The boat runs really good , out of the box Im running a set of gp3900 and a duratrax 3800 . I did trim the out drive up alittle to keep it from running wet . But there isnt much run for adjustment .
