9.3 Soldering
In case that any soldering of wires is required, use only the correct equipment for
the job. There is plenty of information available on the web about proper soldering
techniques; here are just a few key tips:
−
Use quality soldering iron, or soldering station
(
http://en.wikipedia.org/wiki/Soldering_iron
−
Keep the iron tip clean. A clean iron tip means better heat conduction and a better
bond
−
Use a wet sponge to clean the iron tip between the soldering of joints.
−
Keep the iron tip well tinned.
−
Make sure there are no cold joints!
9.4 Materials necessary for small repairs
Repair of minor damage on propeller blades:
-
Use white polyester filler (or epoxy resin), for the repair of small scratches on the
propeller blades
-
Sand away excessive filler with fine sanding paper (initially granulation 360, later
600 and 800, and finally 1000)
