19. A set of SFGs and wing tips are included. They are secured with 3 mm
bolts. We suggest you experiment with each configuration and decide which
works best for your flying style. Attaching the racing wing tips will slow the
roll rate slightly which some flyers may find beneficial. It will also add to the
effective wing area of the model
20. Install your ignition and flight batteries where needed to help achieve
proper CG.
Set-up and trimming
Besides basic assembly, this is the most important part of preparing your
airplane for flight. It can also be the most time consuming, but once your
plane is properly dialed in you will agree it was time well spent. The CG range
basically extends over the width of the wing tube. One of the most practical
ways to check the CG on an aircraft this size is to insert the carbon fiber wing
tube into its sleeve in the fuselage and tie a length of rope around the tube on
each side of the fuselage, forming a loop that you can pick the aircraft up
with. Slide the wings into position, install the canopy and pick up the plane
with the rope. The Slick should balance in a horizontal position. Move your
batteries and radio equipment to achieve this condition. This will give you a
safe starting place for the first flights. One of the best ways to fine tune the
CG for your aircraft is the 45 degree line test. Fly the aircraft in front of you
from left to right (or right to left if you prefer) at full throttle. Pull the aircraft
into a 45 degree up line and establish this line. Roll the aircraft inverted,
neutralize the elevator and pay close attention to what the plane does. Ideally
the plane will continue on this line for several hundred feet before it starts to
slowly level off. If the airplane immediately drops the nose and dives toward
the ground it is nose heavy. If it begins to climb inverted toward the gear it is
tail heavy. There is no need to have the Slick 580 excessively tail heavy to
perform 3D maneuvers.
