Pre Flight to First Flight
Have an experienced pilot assist you with pre-
flighting your new model. Just like having
someone proof read something you’ve written,
having a second, fresh set of eyes, to inspect
your final product is often helpful in avoiding
disaster.
While not an exhaustive pre-flight check, these
are some of the major items that you should
consider using when developing your own pre-
flight check list. Get in the habit of always pre-
flighting your models before each and every flight.
☐
Weight and Balance -
Refer to the Flight
Control Setup section for balancing your
model correctly. Ensure that the
Daddy-O
525‘s
CG is in the appropriate location for
your experience level.
☐
Check Weather - Daddy-O 525’s
first flight
should be in zero wind conditions.
Daddy-O
525
is comfortable flying in winds up to 15
mph so long as the pilot is capable (sober).
☐
Inspect Airframe
for warps and obvious
signs of wear and damage. Do not fly a
damaged or warped model.
☐
Inspect Wing Mounting Bolts
for damaged
or stripped threads and repair/replace if worn
or destroyed.
☐
Inspect Control Surfaces
for center, proper
direction of travel, proper throw, secure
pushrod connections, hinges, and control
hardware.
☐
Inspect Motor
for proper direction of rotation,
secure mounts, wiring, and propellor.
☐
Inspect Battery
for full charge. Never begin a
flight with a partially charged battery.
☐
Inspect Hatch and Cockpit
ensure these
parts are properly seated and latched.
☐
Check Landing Gear -
Repair or replace
worn or damaged wheels and wheel pants.
☐
Clear Area -
Ensure that any spectators are
well clear of the flight line. Have an assistant
handy to keep people back and warn you of
any impending danger (animals, unwary
individuals, small children, etc.).
