building with the prop installed. Check for correct servo direction, reverse as necessary. Center all

control surfaces and tighten pushrod adjusters securely.

Center of Gravity

Measure the center of gravity at the root of the wing where it joins the fuselage, measuring from the

leading edge of the wing. The aircraft should balance at 90mm. Balance the Slick upright. This CG

location is good for your maiden flight. As you fly the Slick, you will want to balance it for your personal

taste and flying style. When trimming your CG, keep in mind that a "neutral" CG (one with which you can

roll the airplane inverted and the airplane neither climbs nor dives) is good for 3D aerobatics, but a more

nose-heavy CG (one with which you must hold some "down" elevator to keep the airplane flying straight

while inverted) is often better for precision flight and is much easier to land gracefully.

NOTE: 90mm is near the front of the carbon wing-spar tube.

When you experiment with CG location, move the CG only small amounts, 1/8 inch or so, at a time. A

small change in CG can have a large affect on flight characteristics.

Control Throws, measured in degrees and millimeters at trailing edge of surface:

Ailerons:

Low 15 degrees, 25mm

High 30 degrees, 45mm

Elevator:

Low 15 degrees, 20mm

High 45 degrees, 65mm

Rudder:

Low 30 degrees, 40mm

High

As much as possible.

Use Exponential on all controls. We recommend starting with 25% on low rates and 70% on high rates.

Adjust as needed to obtain the control feel you want. Consult your radio manual for help in setting

exponential properly. Note that you want to set your expo to *soften* the control feel around center –

most radios also allow you to do the opposite, which will make the aircraft very unpleasant to fly.

Install your propeller.

NOTE: Small brushless motors typically have aluminum prop adaptors with aluminum screws threads.

These threads are easily stripped or broken. DO NOT apply too much torque when tightening your

prop. A wrench is not necessary, it applies too much torque. We prefer a nut-driver.

Be sure to check the motor manufacturer's recommendations for help in selecting a prop. Test your

power system in a safe manner on the ground before ever attempting to fly your aircraft. Range check

your radio system according to manufacturer's instructions.

Make your first flight with the controls set on low rates. During the trimming phase, we recommend

landing with some throttle, not attempting to "dead stick" the airplane. This may mean you need to time

your flights and keep them a bit shorter than usual. After your first flights, check all control connections

and motor and prop mounts for tightness.

Check your rudder pull-pull cables for tightness at the beginning of each flying session. Pull-pull cables

tend to loosen a bit over time, and loose pull-pull cables (cables that flop, or have sag, or that allow you to

move the rudder with your hand without the servo arm moving) are a major contributor to poor aerobatic

performance.

Periodically inspect the battery tray area in your aircraft. This plane does excellent high-speed tumbling

maneuvers, and this type of maneuver puts tremendous stress on the battery tray area. Occasionally

adding a bit of CA glue to the battery tray joints will help your aircraft last through hundreds and hundreds

of flights.
