Setup
DO NOT ATTEMPT FLIGHT IF THE WINGS ARE WARPED.
Remove all warps before flight.
Prior to performing the following flight control surface setup, center control surface then set direction, rate
of travel, and dampening (expo). Ensure that the controls move in the proper direction according to the
inputs on the transmitter.
Important!
The Swift (100) has a very specific aileron starting center point, this
position is drawn on the detail sheet. With the transmitter aileron stick and aileron trim at center position,
the aileron center starting point will be positioned so that the upper surface of the aileron terminates flush
with the upper surface of the fuselage rear deck (F20) - this is roughly 10 deg. relative to the flat bottom of
the airfoil. This slightly “drooped” aileron setting is mandatory to for proper flight control of this model.
DO NOT set the aileron center position in-line with the bottom flat of the airfoil.
The
Swift (100)
is designed to be a very solid sport aerobatic performer. The flight control throws should
be as follows:
Expo settings apply only to radios which feature exponential control.
Preflight
It is recommended that you have an experienced pilot assist you with preflighting your new model.
Just like having someone proofread something you’ve written, having a second
fresh
set of eyes inspect
your final product is often helpful in avoiding disaster.
While not a thorough preflight check, listed below are some of the major items that you should consider
checking when developing your own preflight check list. Get in the habit of always preflighting your
models
before
every flight
.
Weight and Balance
-
Check the balance of your model (C.G., center of gravity). For proper
performance, the model should balance between 1/8 and 1/4 inch
aft
of the main wing spar (W1). Use a
permanent marker or trim tape to mark the underside of the left and right wing half at the CG
measurement as given above. Now, place your
right
and
left
index fingers under the marked CG location
suspending the model from
below
. If the horizontal stabilizer appears to hang level with horizon, the
model is properly balanced and ready to fly. If the nose or tail of the model hang down, move the battery
forward and backward to make subtle changes, or add clay ballast to the nose or tail as required to obtain
proper balance.
Check Weather
-
The
first flight should be outdoors in
zero
wind conditions. The
Swift (100)
can fly in
winds up to 10 miles per hour.
Inspect the Airframe
-
Always check for warps and obvious signs of wear or damage.
Do not fly a
warped or damaged model.
Inspect Control Surfaces
- Always check control surfaces for center, proper direction of travel, rate of
throw, secure push rod connections, hinges, and receiver/servo mounting hardware.
Check Wing Attachment Points
-
Always make sure you inspect for damage and wear. Make sure that
the wing and retaining rubber bands, are properly attached.
