Step 1:

Remove 4 screws located on top of the radio.

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.

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.

No glue past this line

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.

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.

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.

Step 9:

Close out of STVP; now plug

your radio into the programmer.. The

GREEN wire needs to be on the SB1

side on your programmer, and towards

the BND button on the gt3b side…it

was a black wire on the first batch of

kits.

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.
