the pushrod connector for the steering linkage, and the connection for the water cooling system (hidden).
Check that the rudder system is working correctly. Refer to the instructions in section 9.
Before each use, inspect the rudder system and linkage for signs of damage and ensure that they are securely in
place.Ifthelinkage/xingislooseordamaged(e.g.loosescrewsattheentirerearend),repairitbeforeusingthe
model boat. In case of non-compliance, the linkage rod and/or the rudder system may fall off while the model boat
is moving.
This may result in further damage to the model boat (e.g. to the steering servo). Also, you may lose control over the
model boat, which could lead to uncontrollable damage. Refer to the instructions in section 10.
Check that the tube for the water cooling system is attached correctly, otherwise the motor may overheat.

from becoming loose unintentionally.
d) Adjusting the trim tabs
TwoL-shapedmetaltrimtabsareattachedtotherearofthemodelboatontheleftandright-handsides(g.1,position
B). The trim tabs are designed to help the model boat glide and were placed in the optimal position ex works. You can
bendthetrimtabstonetunetheangleofattack.Ifyouwishtoadjustthetrimtabs,removethemfromthehulland
bend them with a suitable tool (e.g. pliers).
A number of factors can affect how the model boat glides. For example the weight of the model boat, the location of
the battery and/or the water conditions (e.g. many or few waves) can affect how the model boat glides. It is therefore
notpossibletoprovideconcreteinstructionsonhowtocongurethetrimtabs.Testthemodelboatseveraltimesuntil
youndtheoptimalposition.
