Front & Rear Toe-In / Toe-Out
前後輪束角調整
a.
Use a
1.5mm Allen wrench
as shown to adjust the front & rear toe-in.
b.
Lengthening the
Turnbuckles
will increase the amount of toe-in, shortening them
will increase the amount of toe-out.
c.
The notch on the turnbuckle indicates the side that has the
right-hand thread
. Use
it as a guide to determine which way to turn the turnbuckle when adjusting its length.
a.
使用
1.5mm
六角扳手調整前、後輪束角。
b.
增長螺距將會增加內束角角度；縮短螺距將會增加外束角角度。
請參照本說明調整您愛車前、後輪的傾角。
Front & Rear Camber
前後輪傾斜角調整
a.
Use a 2.5mm Allen wrench as shown to adjust the front & rear camber.
b.
Turning the upper pivot ball clockwise increases camber towards the negative side;
turning it counter-clockwise increases camber towards the positive side.
a.
使用
2.5mm
六角扳手調整前、後輪傾斜角（如圖示）。
b.
調整上輪軸球頭順時針旋轉將增加負傾斜角；反之，將增加正傾斜角。
請參照本說明調整您愛車前、後輪的傾角。
Ride Height
調整車身高度
a.
The truck ride height can be increased by adding preload clips to the shocks.
Removing preload clips will decrease the ride height.
b.
Compress the spring and insert the preload clips between the spring collar and the
shock body flange.
a.
車身高度可利用避震器調整墊片改變。增加調整墊片可增加車高；反之則降低車高。
b.
安裝或拆卸墊片時，請壓縮避震器彈簧再置入或取出墊片即可。
Slipper Clutch
扭力限制器調整
a.
Use a 7mm nut driver to adjust the slipper clutch.
b.
Tighten the slipper nut until the spring is fully compressed.
c.
Once you've reached the point where the spring is fully compressed, loosen the
slipper nut 1/8turn.
d.
Do not run you truck with the slipper nut any looser than 1/8turn from full spring
compression. Setting the slipper too loose may result in a damaged spur gear.
a.
使用
7mm
扳手調整扭力限制器。
b.
將螺絲上緊至彈簧完全壓縮。
Shock Springs
避震器彈簧搭配
Stiffer springs will give you better handling and higher cornering speed on
smooth surfaces such as asphalt, concrete, and hard pack dirt. Soft
springs are better for rougher terrain, rock crawling and jumping. Softer
springs will increase the rollover tendency of the truck at higher speeds.
較硬的避震器在平坦堅硬的跑道上（例如柏油路面），將可提供較好的操
控性與過彎速度。較軟的避震器適合於崎嶇不平的路面（例如碎石地）以
及跳躍動作，並且可以降低翻車的機率。

Optional Gearing
齒比搭配
Additional gearing is available for your RTA4 SC Racing Truck. Additional gearing allows you to match your engine and transmission to
your driving situation. Bigger gears on the clutch bell (or smaller slipper gears) will result in greater top speed, but will have slower
acceleration from a stop (see chart below). If you change the gearing you will need to reset the gear mesh:
1.
Loosen (or tighten if engine was removed) the four engine mounting bolts located on the underside of the truck until you can just slide
the engine forward and backward.
2.
Slide the engine up to the spur gear until the teeth on the clutch bell are meshed tightly with the teeth on the slipper gear.
3.
Move the engine back a little bit (1/32" or 0.8mm). Check the mesh by holding the smaller gear with one hand and rocking the bigger
gear back and forth with the other. The big gear should rock back and forth slightly with little effort. A gear mesh that is too tight will be
noisy, have lower performance and could ruin the gears.

RTA4 SC
引擎四驅競賽卡車齒輪比可以依照您的需求選擇搭配。較大的離合器罩齒輪（或是搭配較小的大主齒輪），將會提高您愛車的尾速。
但是加速度卻會變弱（可參考下列附表）。若您有變更齒比的需求，您可參照附表建議重新搭配。
1.
將車底板上之引擎固定螺絲鬆脫，直到您可自主移動引擎即可。
2.
將引擎向上移動，直到離合器罩齒與大主齒齒輪緊密接合。
3.
將引擎向下方移動一點間隙（約
0.8mm
），並徒手轉動兩個齒輪是否順暢轉動，來調整間隙。若是轉動時齒輪噪音過大表示，齒輪搭配過
緊，將會降低引擎性能表現。
