18. Final Finishing and Checks
The Vision 3D is now very close to completion – only a few steps and checks
are left to ensure that the model ready and safe to fly:
•
Balance the assembled model laterally (from wing tip to wing tip). Add
tip weight if required to obtain perfect lateral balance
•
Ensure that all servos are moving freely though their full movement
range and are not ‘straining’ at the extremes of movement – this is
particularly important for digital servos which will drain significant
current under load
•
Ensure that ALL radio gear lead connectors are secured to each other
using tape or heat-shrink tubing
•
Ensure that all radio gear leads are restricted from moving about within
the airframe by using tyraps and/or foam blocks. This will stop the
leads chafing in flight
•
Ensure that all fixing bolts have been screwed in place with Loctite.
•
Ensure that all fixing/threaded holes drilled/tapped into the airframe
have been strengthened with thin or medium CA
•
Range check the model, with the motor both off AND running - for
safety please use a helper when checking with the motor running
•
Test your batteries to make sure they are holding their charge and do
not have failing/failed cells.
•
Ensure that any loose debris from building is removed from the
fuselage – preferable by vacuuming it out! This will stop your motor
ingesting any debris through the carburettor hole in the firewall.
