Once all steps are completed, make sure all fittings, nuts and bolts are tightened. Re-install any covers or clips that were removed in the process. Now following the wiring diagram solder all connections to complete the install.
Bend stainless to fit from the end of the jet to point directly into air filter. This step will differ for every RC Vehicle.
Install the .009 NX Jet into the jet fitting.
Once drilled, you may mount the solenoid. Make sure and use loctite on the screws once final location is determined. If loctite is not used vibration may cause the screws to loosen over time.
Using the template provided on the last page of your installation instructions, mark the best location to mount your solenoid. Once you mark this location, center punch and drill using an 1/8th inch drill bit.
Place the battery under the receiver mount and re-install the mount while keeping the battery leads to the side. Make sure all wires are secure and receiver mount sits down in original position.
An example of the perfect battery location on the Savage is under the receiver mount. When it is installed under this area, it might be necessary to re-route a few servo wires to clean up the installation.
Connect the 9-Volt battery terminal to the battery prior to installation into the Savage.
Next, install the provided mini-toggle into the electronics cover that is already drilled. When installing, keep wiring locations in mind so there is no electronics interference.
In order to find the proper location for the wide open throttle switch you must turn your RC vehicle on and take it to full throttle using the Radio. Your throttle servo arm must activate the switch for the system to operate properly. Once the optimum location is determined, mark holes and drill the electronics cover. Also drill a hole for the toggle switch, allowing clearance for all other electronics under the cover
The arrows show the location of the holes that had to be drilled to mount the toggle switch and the wide open throttle switch.
Underneath the electronics cover is the receiver mount. Carefully remove the mount, also take notes of where all wires are routed.
First, remove system from its box. Every NX nitrous system comes with an installation manual. Read all related instructions thoroughly before starting the install. Then Remove the body clips and body from the savage
The best and most secure location for the 9 Volt Battery is necessary for all-terrain performance of the nitrous system. On the Savage, underneath the electronics cover is the optimum location. Remove the three clips holding the cover down, then remove the cover carefully.

This is the installation of a Nitrous Express R/C Nitrous System. Installation was done on an HPI Savage RTR .25. Installation may vary depending on vehicle and engine size. A colder glow plug must be used with the nitrous installation. Consult your local hobby shop to determine the proper plug for your application. In the Savage we used an Odonnell 99.
After all connections are soldered, test system by arming the toggle switch and pull the trigger until wide-open-throttle is achieved. The nitrous solenoid should click. After the system is functioning properly, Open the cartridge crusher, insert a cartridge, and thread the crusher closed until the cartridge is punctured. Nitrous Express is not responsable for those winning races where the knowledge of your nitrous system is unkown to the competitor.
