again before you paint them, as the perspiration in your skin also contains grease
which will soil the surface once more.
•
The wooden parts must be sealed to prevent them absorbing water. Use sanding
sealer (e.g. GLATTFIX, Order No. 207) or clear lacquer (e.g. HYDRO-AEROFIX,
Order No. 926.1) for this.
•
If you are using spray paints, carefully mask off all areas which are not to be painted.
Seal all holes too, as the fine mist of paint penetrates every opening, no matter how
small.
•
Read and observe the instructions supplied by the paint manufacturer.
Colour scheme
We recommend Graupner ACRYLFIX spray cans for the colour finish:
Hull, hatch cover
Hull contrast areas
Maiden run
Charge the batteries fully and test the model's working systems one by one. Seal the
hatch cover with adhesive tape, so that there is no chance of water penetrating the hull.
You are now ready for the boat's maiden run. Take your time to get used to the model's
handling characteristics. Please bear in mind that this boat is capable of very high speeds,
and is therefore not as easy to control as a slower vessel.
Important: when you wish to turn the boat, reduce the throttle (to around half-speed) just
before initiating the turn, otherwise the model may flip over or turn on the spot.
We recommend that you only use full-throttle on the straights.
We hope you have loads of fun building and running your MEGA DRAGSTAR III.
Notes on trimming a Mono racing boat
Model racing boats require careful trimming to ensure that they run with maximum
efficiency. The following points should be checked and fine-tuned in order to obtain a
smooth-running racing boat:
•
Centre of Gravity: the Centre of Gravity (CG) marked on the plan is a good starting
point, and will provide safe handling for the first few runs. If you find that the stern of
the boat tends to jump, the CG should be moved further aft by re-positioning the drive
batteries. If the model tends to take off, move the CG further forward. Make any
changes in small increments until you find the optimum position. The correct CG will
also alter slightly according to the state of the water surface (waves or smooth water).

•
Position of the drive batteries: the batteries should be installed as close as possible
to the stern tube in order to counteract any tendency for the boat to "dutch-roll" (rock
around the fore-and-aft axis). It is also important that the model should be slightly
