STeP 2: iNSTAlliNG The ThroTTle PuShrod Wire

PRO TIP To ensure that your throttle pushrod is installed properly, it's important the your engine's throttle arm be positioned on the

left side of the engine (flip your engine's carburetor around if necessary). The throttle pushrod wire also has to clear the side of the

fuel tank, so a bend will need to be made where the pushrod wire exits the firewall and before the servo.

q Mark the location of the throttle pushrod exit hole on the firewall. For our

Magnum XL .52RFS 4-stroke engine, we positioned the pushrod exit hole

1-1/2" (38mm) up from the bottom of the fuselage and 5/8" (16mm) in from the

fuselage side.

IMPORTANT Mark the position of the hole as close to the same height as

the throttle arm as possible and as close to the throttle arm as possible, but

still far enough away to keep from hitting the fuel tank.

q Drill a 5/32" (4mm) diameter hole through the firewall for the pushrod wire.

You may need to remove the engine and motor mounting beams to make

it easier to drill the hole accurately.

q Make several bends in the throttle pushrod wire to clear the fuel tank and line

1/2"

up with both your engine's throttle arm and the servo arm.

(13mm)

IMPORTANT The measurements of the bends shown are for a Magnum

5-1/8" (130mm)

XL .52RFS 4-stroke engine. You may need to make slightly different bends

1-1/4" (32mm)

depending on the engine you're using.

q Remove the throttle arm from your engine, install the Z-Bend in the pushrod

wire into the outermost hole in the throttle arm, then slide the pushrod wire

through the hole both in the firewall reinstall the throttle arm.

q Open and close the carburetor several times to ensure that the pushrod

wire does not bind.

q Cut away all but one arm from a "4-point" servo horn, then enlarge the hole

in the servo arm that is 5/8" (16mm) out from the centre of the servo horn, using

a 5/64" (2mm) diameter drill bit.

q Install the adjustable pushrod connector onto the servo arm, making sure

not to tighten the nut too tightly. You don't want the pushrod connector loose,

but it should be able to rotate without binding.

IMPORTANT To prevent the nut from loosening during flight, apply a drop of thin C/A to it.

STeP 3: iNSTAlliNG The NoSe SKid

q Temporarily place one nylon mounting bracket onto the horizontal section

of the nose skid.

q Cut one tab off of one nylon mounting bracket and place it over the vertical

section of the nose skid, with the remaining mounting tab toward the centre of

the nose skid.

q Place the nose skid onto the firewall and align it. The edge of the horizontal

nylon mounting bracket (A) should be even with the bottom of the fuselage and

the edge of the vertical nylon mounting bracket (B) should be 1/4" (6mm) in from

the fuselage side.

q When satisfied with the alignment, mark the locations of the three mounting

holes onto the firewall.

q Drill three 5/64" (2mm) diameter pilot holes through the firewall at the marks

you drew, then install the two nylon mounting brackets, using three M3 x 12mm

wood screws, to hold the nose skid in place.

q Install the remaining nylon mounting bracket, using two M3 x 12mm wood

screws to secure the nose skid to the bottom of the fuselage. Again, make sure

to drill two 5/64" (2mm) pilot holes through the fuselage for the wood screws.
