GT3B Hack Kit Install Instructions Written By Austin Hutchison Step 1: Remove 4 screws located on top of the radio. 1
Step 2: There are small plastic latches that also hold the top in place. The easiest way to pull the top cover off is to push these latches open, but it may knar up the plastic alittle. If you don t wish to knar up the plastic you can take a chance and muscle the top cover off, however this may lead to worse damage. To disengage the plastic latches use a small flat head and insert in the places shown on the picture and gently pull up on the cover on the front side its located near the diaganol on the screen pop out, and the back side is located directly across Step 3: With the antenna up pull the top cover off. The rotary knob is attached to the board as well. So it would be smart to gently pry that off the top cover with your fingernails or small flat head screw driver. Other side gently muscle off the cover, the knob will come with it. 2
No glue past this line Step 4: Ok now towards the button side of the screen you ll see 4 holes spaced at.1. This is where the 4 pin header goes, Install the short pins into the holes with the long pins pointed to the antenna side of the case then I suggest putting a dab of hot glue on each end of the header, make sure no glue gets on the front side, it s ok if it touches the backside pins, although try to avoid this as well. It s hard to see the glue in the second picture, so the arrows point to where to put the glue. Step 5: Ok now gently lift the board and pull towards the front. This is to pull the power button out of its hole to lift the board up and out. Ok now gently twist the board up towards the st wheel. To expose the bottom side of the header. Now with the bottom side of the hear exposed lets solder it. To solder a header to a circuit board; pre tin your soldering iron tip lightly, position your iron on one side of the pin so it touches both the pin and solder pad. Then let it heat both for.5-1 second. Now with your iron still touching both apply solder to the other side of the pin, until it melts completely around and down through the hole. Now clean your iron tip. Check to make sure this didn t melt your hot glue and make your header un level, if it did then reheat the joint and push the header back down. Now repeat the steps above for the other 3 pins. 3

Step 6: Ok now flip your board back over and slide the power button back into its hole and push the whole board back down level. Now you ll see there s no way you can plug into the header, that s because you have to cut a slot. Look at the header and at its furthest points take a pair of snips/cutters and cut one step down into the plastic chances are the front side of the cut will bend/flex out to the thinnest point near where the screw goes through, this is ok. Now take a pair of pliers and bend the plastic towards you, you may need to lightly wiggle it back and forth so it breaks off. This new slot will be wre your plug enters the radio to program it. Now it probably doesn t look real neat or very professional. So what I like to do is take a razor knife or hobby knife, and cut all the un even white stretched plastic off into a nice level surface. After you have cut it plug in your cord and make sure it fits, I also like to take my razor and cut a mark in so I know where the plug needs to be, so ones a put the cover back on I don t have to worry about getting it on the wrong pins. 5

Step 7: Put the button covers back on lift antenna up, and pop the top cover back on, so the latches snap back on. Now plug the cord back in, make sure it fits, if it does install the 4 screws and pat yourself on the back because you just finished installing the hack kit to your radio. Now lets program it. 7
Step 8: Now you need to download and install the programming software, ST visual programmer. It can be download with/from this link http://www.overkillrc.com/gt3b/stvpinstall/sttoolset.exe If you are running windows 7 and possibly vista you may need to install this patch as well, which can be found at this link http://www.overkillrc.com/gt3b/stvpinstall/sttoolset_pack24_patch.exe Make sure restart your computer after you install. Once you have rebooted your computer, open up ST Visual Programmer and make sure you have these settings, first time you open it, it should let you choose, however if it doesn t, click on the configure tab, then configure ST visual programmer. 8
Step 9: Close out of STVP; now plug your radio into the programmer. There is a triangle on the plugs of your harness. These arrows need to be on the SB1 side on your programmer, and towards the BND button on the gt3b side it s also the black wire. Now plug the programmer into the computer with the supplied USB cord. Now open up STVP. o Click File, open, Select the firmware you want to use. o Now click program, Current tab. There should be a status bar on the bottom. It will program then verify. Don t do anything till it says verification complete. 9
Step 10: Now unplug your radio, and start setting up your models, have fun. 10
