word on the forums is that the blades from OF Helitechnik in Germany
are the smoothest flying blades around. I ordered a matched set
of 5 from StarwoodModels.com, and after a few weeks (they got held up
in customs, who probably thought they were Samurai Swords) they
arrived. They are 800mm Semi Symmetrical blades with a 14mm
root, and 5mm bolt holes, so they were a custom job as well.
blades are airfoil shaped. Unlike most RC Helicopter
blades, which are symmetrical (same on both sides) to allow
inverted flight. Semi symmetrical blades provide more
lift per blade.
The first job was to fill in the
pinholes, voids, etc that were in the blades. On the plus side,
they were balanced to .1 grams (that is .03% or 3 hundredth's of one
percent variance, pretty darned good). On the minus side, they came
with blemishes and voids that you would never see in a
Curtis-Youngblood or Align blade.
I built a spray jig, and Bryan came over to lay on the base white
coat. I wanted them to be as evenly applied as possible over the
5 blades, and hell, he does this professionally!.
I masked and sprayed on the
black pattern, as well as the yellow tips. after those dried, I
applied the dry transfer lettering, and Bryan came back and applied the
After they dried, we wet
sanded them with 1000, 1500 and 300 grit, then buffed them to
perfection! These really look nice.
