Sail trim
The Micro Magic is designed as a regatta boat and offers many settings to trim, which you
can use, but do not necessarily have to use the cozy sailing. In this chapter we explain the
most important control variables, their respective influence on the sail behavior and how you
can take advantage at different wind / wave conditions. The descriptions are deliberately kept
simple and reduced to what you can use in the model sailing hobby on your Micro Magic RTR
as a beginner.
Mast tilt
Change the position of the sail pressure point, mast backwards -> more weather helm, im-
merse mast forward less weather helm, however, higher tendency for gusts with the bow.
The mast tilt is adjusted by moving the plate on the deck.
Mast deflection
If the luff of the mainsail fit, a little more bend -> flatter mainsail profile, too much bending re-
sults in a diagonal crease in the mainsail.
Main sail tension
Is set on backstay and forestay, should match the wind strength. Increase the main sail tensi-
on with increasing wind, otherwise the jib twists on too strong and the boat luffs gusts exces-
sively. Once the jib during “downwind“ course is shuttling back and forth, the tension is slight-
ly too high. Please note that a change in the tension at forestay backstay or the tension of the
opposite Stages affected, the mast deflection changed so that the profile of the mainsail
changed and especially the twist on both sailing. Also check the tension of forestay if you ha-
ve adjusted the tension on a Stag.
Shroud tension
Your Micro Magic mast is designed so that it could be driven without the shrouds. You should
not stand even stress it wit too high shroud tension . If you want to remove the shrouds, plea-
se do not forget to remove the eyelets and to cover with seal the holes.
Forestay tension
The forestay should always be tightened to a lenght so they are straight and unwrinkled. Do
not try to compensate any other wrinkles in the sail by strongerly tightening the luff. Because
sailing necessarily needs on both the luff sails.
Sail flection
A lower profile also produces more power but a higher resistance. Basically, a little more cur-
ved one moves with weaker wind or wave in the sail. In stronger winds shifting the attach-
ment points on the boom yardarm slightly aft and makes the profile flat. The foresail usually
has something less than the main tummy. By solely adjusting a sail you change the position
of the sail pressure point. To be able, within certain limits, for example, a little too porting boat
with more deflection in the foresail or less deflection in main sail makes a little quieter (porting
vice versa).
Opening angle of the sail
When you open the sails, the resulting driving force rotates more forward. The heel decrea-
ses but the boat also leaves less height. While sailing set with the remote control permanent-
ly the opening angle of the sail so that it fits to the desired course. To trim, you can change
the position of the sail pressure point, starting from the basic setting of the rig through a slight
change to sail similar to the sail deflection. A boat can port with more opening angle of the jib
or something denser large neutral be held (weather helm vice versa).
