Flying the Ultra-Micro 4-Site

Having followed the proper receiver initialization and arming procedures,

confirmed proper control of the servos and motor, and found a suitable flying

area, your 4-Site is ready for flight. Start your first flight using the low

rate set tings to become familiar with the flying characteristics before

increasing the throw of the control surfaces.

Place the 4-Site in position for takeoff (facing into the wind if flying outdoors).

Gradually increase the throttle to ¾ to full, and steer with the

rudder. Pull back gently with the elevator and climb to check trim. Once

the plane is trimmed out, you can begin exploring the flight envelope of

the 4-Site.

Note: If you are flying the 4-Site outdoors, we highly recommend that your

first flight be on a very calm day and that your first flight take place

over grass.

Note: The Ultra-Micro 4-Site flies much like the larger version or other

aerobatic flat foam type aircraft. If you have not flown one of these

before, you will notice that you must use the rudder during flight.

Using only the ailerons will not turn the 4-Site properly. The ailerons

will only induce roll. A combination of Ailerons, Rudder and Elevator

will be needed to fly the 4-Site.

• IN THE UNFORTUNATE EVENT OF A CRASH OR PROPELLER STRIKE, NO

MATTER HOW MINOR OR MAJOR, YOU MUST LOWER THE THROTTLE STICK

AND TRIM TO THEIR LOWEST POSSIBLE POSITIONS BEFORE IMPACT TO

PREVENT DAMAGE TO THE ESC OF THE RECEIVER UNIT OR DAMAGE TO

THE AIRFRAME. WE HAVE FOUND THAT IN THE EVENT OF AN IMPENDING

CRASH IMMEDIATE REDUCTION OF THE THROTTLE WIILL GREATLY REDUCE

DAMAGE TO THE AIRFRAME.

Failure to lower the throttle stick and trim to the lowest possible

positions in the event of a crash could result in damage to the ESC in the

receiver unit, which may require replacement of that unit.

Note: Crash damage is not covered under warranty.

Note: The box for the 4-Site has been designed to use as a carrying

case. This will prevent damage to the airframe during transport

and storage.

Optional Speed Brakes

You can choose to fly your 4-Site with optional speed brakes. These are very easy

to install and will slow the flight envelope of the airframe. The increased drag will

drain your flight battery slightly faster though as you will need more power through

the flight.

1. Use foam-safe CA (PAAPT25) to glue the speed brakes onto the tabs at the rear of

the outer plane struts. You can lightly tack glue these in place, giving you the option

to remove them if you would rather fly without them.
