XIV. ROTOR BLADE SELECTION
It is recommended that a blade length of 680mm to 700mm be used. A good quality rotor blade is suggested.
Miniature Aircraft USA offers a variety of high quality rotor blades suitable for the Fury Tempest.
XV. FINAL MECHANICAL AND ELECTRONIC SET-UP
NOTE
: The following procedures will be described using a pitch gauge, fly bar lock and paddle gauges. The
use of these items is highly recommended since without them an accurate set-up is very difficult. Refer to the
beginning of the manual for the correct order numbers.
A. Install the rotor blades, noting that the leading edge of each corresponds to a bell mixer on each side of the
rotor head (clockwise rotation). The pivot bolts must be tightened the correct amount. This is best described
by indicating what is too loose and too tight. If the model is leaned to one side and the blades swing together
by their own weight, the bolts are too loose. If a fly bar paddle is held in one hand, a blade tip on the other
and an effort is made to fold the blade, the result should not deflect the fly bar more than 25.0mm (1.0@).
These are approximate values.
B. Install a flybar lock onto the rotor head. Install a pitch gauge onto one rotor blade.
C. Set all transmitter trim levers and servos/bell cranks at neutral as described in Section XII, Step 2. The swash
plate can now be adjusted to a level position (perpendicular to the main shaft and parallel to the main
gear/frames) by adjusting the rods below it. This procedure can be assisted by the use of a straight-edge or
bubble level placed across the top surface of the swash plate outer ring. The final confirmation is done at the
rotor blade. Read the pitch at the blade (the exact value in degrees does not matter at this stage). The pitch
reading should not change as you rotate the head, checking it at each 90 position (starting directly over the tail
boom for example). Miniature Aircraft USA offers an excellent tool for leveling the swash plate, order #0513.
NOTE
: Adjustments should be split at opposite sides (half turn longer on the left side, half turn shorter on the
right side, for example).
D. Adjust the rods (#0337) from the washout to the flybar control arms until the flybar arms and the wash out
arms are level.
E. Adjust the rods (#120-25) from the swash plate to the bell mixers until the bell mixers are level with the
flybar.
F. The fly bar paddles must now be aligned with the swash plate. This can be confirmed by visually comparing
the paddles to the swash plate from the side view. Some pitch gauges will adapt to the paddles or you can use
the X-Cell paddle gauges #0510-1. The fly bar lock can be removed for this step if tilting the fly bar helps
your view. Adjust each paddle until they are level and parallel to each other.
G. The collective pitch range can now be adjusted. It is suggested that the “3-D” settings be used initially by
everyone (as a set-up guide) then modified electronically to suit individual needs (such as beginners or
intermediate pilots). All “3-D” settings should only be set utilizing an “idle-up” function within the radio. If
you are a novice, this idle-up function can be deactivated later (prior to flight). As a novice or expert, you
will benefit by having the desired “zero” or “neutral” mechanical set-up which results from using the 3-D
settings as a starting point. Refer to Table 4: Initial Pitch/Throttle Settings:
