Notes on the radio control system 

 

Before switching the radio control system on, please read the instructions supplied with the transmitter you 
intend to use to control the boat. 

 

The receiver is switched on and off by operating the On / Off switch. 

 

When switching the system on: always switch the transmitter on first, and only then the receiver. 

 

When switching the system off: always switch the receiver off first, and only then the transmitter. 

 

Check the model’s working systems in turn. If any of the functions do not operate in the direction you pre-
fer, you can change them using the servo reverse facility at the transmitter: on simple transmitters this will 
be  by  means  of  mechanical  switches;  on  more  sophisticated  types  by  software.  Refer  to  your  transmitter 
instructions for information on how to operate the servo reverse function. 

 

Never attempt to sail the model with flat batteries in the transmitter or model. The dry cells in the model are 
subject  to  quite  heavy  loads,  and  will  be  flattened  fairly  quickly;  for  this  reason  you  will  need  to  replace 
them more frequently than the transmitter batteries. If you are not sure whether the cells are still sufficiently 
charged, it is always safer to replace them. Your model shop will stock battery testers which you can use to 
check the state of your batteries. 

Notes on building the model 

 

Please refer to the photos and the drawing when assembling the model. 

 

If you do not understand the technical terms relating to sailing boats, you can download a sketch showing 
the basic terminology from the Internet website www.micromagic-rc-segeln.de. 

 

Before you start building the boat, please take the time to study the plan and read right through the instruc-
tions for the boat and the transmitter. 

 

Please bear in mind that many tools can be dangerous if misused or handled carelessly. 

 

Deploy the receiver aerial as high up in the hull as possible, and wind the external part of the aerial round 
the backstay. Reception will be very poor if the aerial is positioned below the waterline, and effective range 
will be greatly reduced. 

 

Completing the rig requires a few knots; they can be secured with a small drop of cyano. 

 

If the circular reinforcing stickers on the sail come loose, stick them back in place using a drop of cyano. 

Assembly instructions 

 

Assemble  the  parts  of  the  boatstand,  and  apply  glue 
to all the joints for additional strength. 

 
 
 

 

The  next  step  is  to  install  the  rudder  system.  This  is 
accomplished by setting the rudder servo and the rud-
der  blade  to  centre,  and  securing  the  tiller  arm.  Se-
cure the two rudder linkages by tightening the shroud 
tensioners. Note that the control cords should only be 
tightened  to  the  point  where  they  are  just  taut;  if  you 
over-tighten  them,  the  rudder  servo  may  be  over-
stressed.
