As threadlocker varnish L, you can use Loctite 221 with low hardness; as threadlocker varnish T, you can use Loctite 243
with medium hardness.
In practice, however, it has proven sensible to use medium-hard threadlocker varnish for all screw connections to be
secured. To be able to loosen the screws again for servicing, we advise against using threadlocker varnish with high
hardness.
• Open the respective packaging bag only when the components are actually needed for the respective assembly section.
For this, place the individual components in a separate component holder (empty freezer box, etc.).
• Only perform the individual assembly steps after you have understood all the pending activities and know precisely which
component must be attached where.
• The included screws have different lengths and heads. Ensure that you install the right screws in the right places.
• Only use the material included with the construction set. Do not try to modify the model with additional and unsuitable
assembly material. In case of defect, replace only the parts and components concerned by genuine parts from the spare
parts list.
• Use high-quality assembly tools like a hexagon wrench with precisely ground and hardened screw drives. Cheap tools
tend to overturn and damage the screw heads. An overview of which tools and materials are needed additionally can be
found in the manufacturer’s manual on page 4.
• Only assemble the model helicopter on a suitable basis (soft cotton cloth, etc.) to protect the mechanics from scratches
and damage.
