Hi all i have a Dave Frank Miss rock sport hydro hull length is 21 1/2'' beam is 11 3/4'' hull+ hardware+lipo=38 oz total weight the unfortunate part of this project is very limited interior space managed to sqeeze a Sea king 120 amp esc under front starboard deck im limited to a 2s 2500 mah 50c lipo in the battery tray and a 28mm dia x45mm b/l motor under the cowl . My goal speed wise around the 43 mph range. What kv rating would work? What brand of motor? Regards Andris Golts.
