We will begin by removing all nitro related items like fuel tank, GXR 28 engine, tune pipe and complete radio tray. Start by removing the 4 screws that hold the GXR 28 engine in place, then use a 2mm hex driver to remove the pipe. Gently lift up and out! Removing the fuel tank is a snap, just remove both bottom screws. The radio tray is held in place by 8 screws, remove these from the bottom.

Open IF344 Center Differential Gear Set, follow the supplied instructions. Please refer to your Inferno GT2 Maintenance Manual if you need more examples of proper diff building. In the project GT2 VE we used 30,000 weight #SIL30000 silicone in the center differential. This will give you a good base to start from.

2 Speed Removal
Flip the chassis upside down and remove the 4 phillips screws that hold the center diff in place. Note: F/R center dogbones will fall out at the same time the center diff is removed. Now remove the top place screws, this will allow you to split the center diff into 3 parts F/R mount and 2 speed assembly. The brake caliper will need to be removed at this time.

Center Differential Assembly
Take the plastic diff mount and place it on the 8x16mm bearing, press it firmly in place. Take the machined aluminum motor mount and slide it onto the 8x16mm bearing and press firmly. Take the top plate included in IFW451, pay close attention to the way the top plate is facing. Use the supplied 3x10 machine screws (x2) for the motor mount area, use the stock screws 3x10 self taping screws (x2) on the plastic mount. Tighten till snug, a bit of blue loc-tite on the 3x10 machine screws will provide you added security. Install esc cable guide 7 onto the top plate using the 3x8 machine screw (x1) supplied.

Battery Tray Assembly
Take item 13 support plate and place it under the radio box and mount it using points shown above. Item 12 is a rear center dogbone guard that helps keep the rotating dogbone away from any vital components. Use above mounting points to secure it using the supplied 3x8 machine screws (x2). 6 gear guard will slide onto the battery tray and secure with the provided 3x8 machine screw (x1).

Security Strap Installation
Thread the strap through the 1st battery hole, note what direction the security strap is facing. Install and secure all 3 straps across the tray.

Installing Your ESC
Place your ESC onto the designated spot on the battery tray once you have found the proper placement secure it down with double sided tape. After the ESC is nice and secure guide the main ESC cable through the opening shown in the illustration below. Please note there is a clip on the bottom side on the battery tray, hook the cable into this clip for proper installation.

Part 2

Installing Your Battery Tray
Use caution when using sharp items!
Cut highlighted item above, use an exacto knife or even side cutters, cut till its just flush. Place battery tray onto the chassis making sure to align the rear 4 tabs for proper fit. Use the supplied 3x12mm screw place it in the center of the bottom of the chassis as shown above, use a 3mm washer with a 3mm nut, tighten it till snug. Two 3x12mm screws are needed to secure the last two points with a 3mm nut, tighten till snug!

Installing Center Differential
Take item 17 (rear motor support) and use the supplied 3x8mm flat head screw to secure it down to the chassis. Note: GT1 owners will need a new center dogbone #IF144 and GT2 owners will need #IS009. This is needed because the center diff sits farther back. Take IS009 and place it into the front coupler now take the stock rear dogbone and repeat. Take ORG04 O-Rings and place 2 in the rear and one in the front center diff. *Tip: You can use fuel line just cut it to about a 2mm lenght. Now place the center differential with motor onto the chassis making sure that the holes align, use the original 4x15mm self taping screws and secure the plastic diff mount. Now secure the aluminum diff mount by using the supplied 4mm nuts and 4x12mm screws. *Tip: To make installation easier pre-thread the nut, this will allow the screw to set much easier. Place each nut in the opening on the bottom of the motor mount and gently start threading the screw into the nut, once it feels snug secure it donw all the way.

Installing Your Radio Box
With your center differential installed, the next step will be a snap. Take your ESC plug and thread it through the post that holds the ESC wire guide. Once through, rest the wire in the wire guide channel. Next step is building your radio box, this is simple, take the radio box #3 and take your servo and set in in place. Use the supplied servo supports #8, slip them under the servo and hold them in place with a set of needle nose pliers. Screw the servo down using the stock set of self taping screws.

Installing Your Radio Box
Place the ESC wire in the radio box by using the access point at the bottom of the box. Now plug in all components to your receiver. Please use these points to mount your radio box to your GT2 chassis. Use the supplied 3x10mm flat head screws.

Installing Foam Padding
Take the 2mm strip of foam and remove the paper backing making sure you align one corner and press it in place till you get to the opposite end of the tray. The 5mm foam strip will need to be cut into approx 1/2inch sections and place towards the inside of the tray. Remember to press firmly so they don't come off during operation.

Setting Your Gear Mesh
Loosen both 3x8mm and 4x10mm motor mount screws, this will allow you to freely move the motor back and forth. Slide the motor towards the spurgear then tighten both screws till snug. Cut a piece of paper and place it between both gears if you're able to pass the paper through relatively easy then your mesh is too loose. Loosen both screws and bring the motor mount in just a tad, repeat the paper test, you want the paper to just get crimped as you roll your spurgear. Once the desired mesh has been set remove one screw at a time and apply a little Loc-Tite to the threads for added security.

Your build is complete!
