This is my conversion of an "NQD Spurt" ready-to-run boat. The 'toy' 40Mhz radio gear has been replaced by 'proper' 27Mhz components and the on/off speed control has been removed and a 35Amp forward only (aircraft type) ESC fitted. The bang-bang rudder system actuator has been upgraded to proportional servo control. The 1800mAH NiCad battery - which lasted for about a minute! - has been replaced by a 4300mAH NiMh pack.
