at the Christchurch Society of Model and Experimental Engineers in Halswell, I noticed two guys at our boating pond. Curiosity got the better of me, oh well the work can wait anyway, and I found them both running fairly
high speed jet boats.
My questions answered I now knew that a toy boat readily available here in New Zealand, could be retrofitted with replacement radio control, a better electric motor and Electronic Speed Controller.
Youtube clips provided ample examples of such modifications. Many showed water cooled motors and controllers being fitted. I already had a spare brushless motor and ESC🙂. Within days I had my own yellow jet sprint replica. And yes, out of the box it was very much only a toy. Steering was straight or full left/right. Speed control was ALL or NOTHING, and the boat’s speed minimal.
