Adding Radio Control to a Large Precedent Fairey Huntsman or Perkasa Model Boat

We have recently had a number of requests for advice of what accessories are necessary to convert some of our best-selling model boats into a Radio Controlled models. 

Starting with the classic Precedent Fairey 46.5" Large Huntsman (shown above) and the Precedent K D Perkasa 49" Large Model Boats (shown below) we have put together a rough list to be used as a guideline, although there are lots of variations and choices available.

First of all you will need the excellent:
Carson Reflex Stick Pro 2.4GHZ 2 Channel Transmitter RC System which is an ideal radio for classic two stick control with the benefit of interference free 2.4Ghz operation. A Carson (Acoms) Servo is included in the box.

With this we suggest you use:
Viper Marine Forward & Reverse Speed Controller 25Amp which is a Brushed Speed Control designed specifically for use in RC boats. This Speed Controller has a 25Amp motor limit, which means you can use any DC Brushed motor as long as the current drawn by that motor does not exceed 25Amps under load (with the prop connected, under water).

Other required products include:  

Lead Acid Battery 12V 7Ah - BAT12V7
Electric Motor 12V 10.8Ah - EM850
M4 Fine Line Stainless Prop Shaft 325mm - 4342
Universal Coupling Joint - UCJ
Coupling 4mm threaded for PSU2 Prop Shaft - UCF/M4
Coupling 6mm for Motors & Gearboxes - UCF/6
Large Rudder 67mm Blade Depth - RAU4
Graupner 2 Blade Racing Propellers - G2303/42

Thats basically what you'll need for turning your prized showpiece into an amazing remote control model !
