Having a clear out and found some old Kyosho Mini Z Racing boats from our display models from years ago.A good clean up ans chase out the wildlife living insides, a oil and grease up.
Originally Kyosho mini Z racing boats, no longer available, fiited with small batteries 6v Nicads, also no longer available. so refitted with a new battery tray a 3g Lipos and a lot of trimming to get balance correct, models are fitted with adjustable skegs on the outdrive for different weather conditions.
All in all a good conversion, you can still get the bodies for the 2 different types of boat, and fit ex small aircraft radio and motor, escs and mini rudder servo ( Lambougini model comes with servo) etc from a wrecked plane, should give great performance with out the reverse. see it in action on You tube here
