vortex prop

[kssi]

i ran my vortex 22 hydro today, i used a stock bj, a stock sv, and a 42-55. both stock props ran great . but the 42 i could not even go half throttle and it would just spin out ,soooooo about what should my prop be with a ammo 23 and a mystery speedo, oh and 2 2cell 5400. thanks kenny

You may want to try an octura x437,x440,or x640.
