Cruising speed about 40knots++ It should still be working, it hasn´t been run over by Kenneth´s much slower boat!!!! Graupner Hydro Sprint (Micro Hydro) Engine: Kyosho AP29L (ducted fan) Rc: Hitec Batteries: 9,6 V 500 mah which gives a running time of  2-3 minutes. ESC: Graupner v60. This powerful engine needs a high quality ESC. Prop: Graupner stock propeller but I`m looking for for other propellers as well.
