Great Planes Spitfire 25 GP/EP ARF - GPMA1478 - Manual (Page 24)

The Combat Spitfire ARF includes optional landing gear for
those modelers who choose to sport fly the model and
would benefit from using landing gear. The included landing
gear is recommended for paved runways only. If you plan to
fly the Combat Spitfire ARF in combat competition, we
suggest omitting the gear for reduced weight and
increased maneuverability.
❏
1. Locate and remove the covering from the landing
gear slots on the underside of the wing.
❏
2. Using four 3mm wheel collars and four 3mm set screws,
temporarily install the wheels onto the landing gear centering
them on the axles. Tighten the set screws against the axles.
❏
3. Remove the wheels and wheel collars and grind flat spots
on the axles where the set screws made marks from being
tightened. A rotary tool such as a Dremel
® with a cut-off wheel
or a metal file can be used to make the flat spots.
❏
4. Reinstall the wheels onto the axles using the wheel collars,
set screws, and thread-locking compound. Be sure that the
wheels rotate freely. Oil the wheels at the axles if necessary. Fit
the gear into the slots in the wing. Position four landing gear
straps over the wire, evenly spaced and at an approximately 45°
angle as shown. Mark the locations for the strap holes onto the
wing and drill 5/64" [2mm] holes at the marks
(be sure not to drill
completely through the wing!). Thread a 2.5mm x 10mm self-
tapping screw into each hole and remove it. Apply a couple
drops of thin CA glue to each hole to harden the wood. Install the
straps over the landing gear using eight 2.5mm x 10mm self-
tapping screws.
❏
5. Trim the covering from the slot cut into the tail skid. Glue
a 3mm washer into the slot so it is flush with the outside edges
of the tail skid. The washer will prevent the tail skid from rubbing
away when flying from a paved runway.
