Page 3 X-Factor2 running as quickly as possible. The Tuning Guide included within this Operations Manual deals with different chassis setups and even has a special section for setting up your X-Factor2 for rock crawling - what the X-Factor2 is best at! We've also included how-to's on installing some of the most popular hop-ups that are available for your X-Factor2.
Page 4: Section 1: Recommended Tools And Supplies
This section lists the recommended tools and supplies that you need to purchase and have onhand to finish assembling and to run and maintain your new XTM Racing X-Factor2. We have tested these items extensively with the X-Factor2 and found that they offer the best in reliability and value.
Page 5: Section 2: Becoming Familiar With Your X-Factor2
The switches are located under the removable plastic cover. Steering Wheel: Controls the X-Factor2's steering. Turn the wheel to the right and the truck turns right. Turn the wheel to the left and the truck turns left. Steering Dual Rate Control Dial: This dial adjusts the overall travel of the steering servo. Push the dial forward for maximum steering (125%). Pull the dial back to reduce steering travel (minimum 60%).
Page 6 Torsion Bar: The torsion bar prevents excessive chassis roll during cornering. The X-Factor2 includes two torsion bars which can be removed. Wheel/Tire Assembly: The X-Factor2 includes molded rubber tires with a tread pattern that is good for most off-road applications. The wheels are...
Page 7: Section 3: Preparing To Run Your X-Factor2
SECTION 3: PREPARING TO RUN YOUR X-FACTOR2 Now that you are familiar with the major component parts of your X-Factor2, and with the functions of the Hitec Aggressor transmitter, it's time to prepare your X-Factor2 for its first run. IMPORTANT Before continuing, please double-check that you've read and understand the warnings printed on page # 2.
Page 8 If you would like to upgrade to a rechargeable NiCD or NiMH battery pack, instead of using Alkaline dry cells, we suggest using the XTM Racing 5 cell 1000Mah NiMH RX Battery Pack (P/N 145801). Not only is this battery pack rechargeable, it will operate the servos at a higher power rating, because of the 5th battery cell.
Page 9 If the radio system does not operate properly, please refer to the troubleshooting guide starting on page # 25 before continuing further. Never attempt to operate your X-Factor2 if the radio control system is not functioning properly. Doing so could be harmful to others around you and/or to you or your truck.
Page 10 To prevent damage to your engine, we strongly recommend "wetting" the air filter element, using a high-quality filter oil or after-run oil. X-FACTOR2 UPGRADE TIP If you will be running your X-Factor2 in extremely dusty conditions, we suggest using a prefilter sleeve over the air filter.
Page 11: Section 4: Becoming Familiar With The Xtm Racing 24.7 Nitro Engine
WARNING!! PLEASE READ THIS INFORMATION BEFORE PROCEEDING!! Your X-Factor2 comes equipped with the user-friendly and powerful XTM Racing 24.7 nitro engine. Before starting the engine for the first time, you MUST read this section very carefully. This section details the different parts of the engine's carburetor and how to adjust the carburetor's needle valves to tune the engine.
Page 12: Section 5: Fueling And Starting The Xtm Racing 24.7 Nitro Engine
SECTION 5: FUELING AND STARTING THE XTM RACING 24.7 NITRO ENGINE WARNING!! PLEASE READ THIS BEFORE STARTING YOUR ENGINE FOR THE FIRST TIME!! If at any time the pull-starter becomes very tight or difficult to pull - STOP! The engine has become flooded and the excess fuel must be removed from the engine or damage to the pull-starter and/or engine could occur.
Page 13: Section 6: Breaking In The Xtm Racing 24.7 Nitro Engine
SECTION 6: BREAKING IN THE XTM RACING 24.7 NITRO ENGINE The XTM Racing 24.7 engine is an ABC engine. The cylinder sleeve is tapered at the top, causing severe resistance when the piston moves through the top of the stroke. This is normal. When the engine heats up to operating temperature, this resistance will decrease and the proper clearance will be achieved.
Page 14 Glow Plug Recommendation: The glow plug can make a big difference in how your engine performs. We recommend using a "hot" heat-range glow plug intended specifically for performance engines like the Thunderbolt # 3 (P/N 115559) or the McCoy MC-59 (P/N 690215) during the break-in process.
Page 15 Step 2: Fine Tuning the Engine After your engine has been broken in, you can set the high and low speed needle valves for optimum engine performance. IMPORTANT Be careful to never lean out the engine too much. Remember that the lubricants for your engine are suspended in the fuel.
Page 16: Section 7: Installing The Body
SECTION 8: MAKING CHASSIS ADJUSTMENTS Chassis alignment and geometry are important if you want your X-Factor2 to perform well. A good performing truck means a truck that is easier to drive, too. Follow our guidelines in this section to get the most out of your X-Factor2.
Page 17 PRO TIP With the torsion bars removed, the X-Factor2 will be much more prone to rolling over at high speeds, especially during cornering. Continued On Next Page...
Page 18 Hold the spur gear firmly, tighten the slipper clutch adjustment nut completely, then loosen the nut 2 full turns. Step 6: Adjusting the Brake Linkage The brake linkage in your X-Factor2 is preset from the factory; however, after running the truck for awhile you may find that the brake linkage needs adjusting.
Page 19 Step 9: Adding Reverse to Your X-Factor2 The X-Factor2 does not come with a transmission that includes reverse, but a separate reversing kit is available from XTM Racing. This kit comes with everything you need (except a servo and 3 channel radio control system or R-Box Electronic Reverser for use with 2 channel radio control systems) to give your X-Factor2 reverse capability.
Page 20: Section 9: Setting Up Your X-Factor2 For Rock Crawling
You should definitely remove the two torsion bars from the suspension, so that the suspension can articulate as much as possible. For better low-speed crawling, you may want to change the stock 15T clutch bell to the XTM Racing 13T clutch bell (P/N 149525).
Page 21: Section 10: Maintaining Your X-Factor2
SECTION 10: MAINTAINING YOUR X-FACTOR2 Following a simple maintenance schedule will ensure that your X-Factor2, 24.7 engine and radio system operate in top condition every time you use them. It is strongly suggested. Check the foam air filter element for dirt blockage. If the foam is dirty, remove it from the filter housing and wash it in liquid soap and warm water.
Page 22: Section 11: Hop-Ups Installation
SECTION 11: HOP-UPS INSTALLATION This section describes the installation of a few of the more popular hop-ups that are available for your X-Factor2. These hop-ups include: Tuned Exhaust Pipe Set (P/N 145824) Wheelie Bar Set (P/N 149625) Axle Adapter Set (P/N 146110)
Page 23 Installing the Axle Adapter Set Installing the axle adapter set will allow you use 14mm hex-style wheels on your X-Factor2. Each axle adapter set comes with two axle adapters, so you'll need two sets to do all four wheels.
Page 24 Slide the new axle adapter into the steering knuckle, then reinstall the steering knuckle. Installation is the reverse of disassembly. IMPORTANT You must use Blue Lock-Tite when reinstalling the two steel screws and the steering tie-rod bolt. This will ensure that the screws don't loosen during use. Slide the new steel pin through the hole in the axle, then slide the hex-style adapter onto the axle and over the steel pin.
Page 25: Section 12: Troubleshooting Guide
This troubleshooting guide has been provided to help you diagnose and solve most problems that you may encounter with your X-Factor2 RTR Nitro-Powered Monster Truck. Most problems encountered can be solved by carefully following the problem-cause-solution sections. If you cannot solve the problem using this troubleshooting guide, please feel free to contact us at the address, phone number or email address shown on page # 2 of this Operations Manual and Tuning Guide.
Page 26 IF YOU'RE HAVING A PROBLEM WITH THE X-FACTOR2 CHASSIS: PROBLEM CAUSE SOLUTION 1) Truck pulls to one side A) Steering trim out of adjustment A) Readjust trim to center both wheels (P9) B) Toe angle out of adjustment B) Readjust toe angle (P16) C) One wheel is hanging or has damaged bearing C) Remove wheel and clean bearing.
Page 28 Hitec/RCD North America. This includes the transmitter, receiver, throttle servo (excludes steering servo which is warranted by XTM Racing), battery box and on/off switch. Do not return the radio system to Global Services. It must be removed from the truck and returned to Hitec/RCD at the address shown: Hitec/RCD, Inc.
