I flashed the new firmware now the transmitter won't come on? In specific order, I pluged the wire into the transmitter then into the programmer. Then usb in the programmer then into the computer. Started software, tried to flash with remote off, turned remote on restarted software. Opened firmware file. Flashed firmware file. It said verified. I then unpluged usb from computer. Turned remote off then tried to turn back on and got nothing. LCD is just black. Can't flash firmware again if it won't turn on. Any ideas?
You shouldn't have to be powering your radio on to program it. Are you using one of my kits?
I have my GT3B set up to run my XR10 crawler and after a few years of use I starting to have some issues.
All works fine for maybe half a battery but then only the front wheels and steering work.
When I disconnect the battery and connect it again it will work for five minutes and the rear wheels will stop again.
If anyone has any idea what the issue is I would be grateful for some help.
cheers.
What battery are you disconnecting? The one in your crawler?
This sounds like an esc issue.
Is there anywhere to purchase the hack kit in Canada?
Not that I know of, If there is its not my kit. First class shipping rates to canada isn't that expensive though...
Having some problems with a remote I purchased a few months back. The roller/ selecter button no longer works properly. The push button seems to be broke. Any way I can send it in for service? Replacing that part is above my skill level. Obviously I would pay for shipping/parts.
I could try to fix it, but I haven't been very happy with the results in the three I've fixed so far. They all worked just fine afterwards but I had issues getting good solder joints.
I'm very interested in purchasing a hack kit from you losikid. Hope ya get em on stock soon. I'll be checking your website from time to time to check up.
Order one, it'll ship a couple weeks later...it should called a lead time not backorder. But I haven't got around to changing it.
I'm a full time engineering student, work a part time job, and do OverkillRC. I can usually only sit down a fill orders once a week, or every other week depending how busy I get. Which is why I have a 1-2 week lead/backorder on them
I have a hacked ct3c. This is my first hacked radio. I got it used and don't have the program card and link wire. How do I know what is what on this radio? I'm lost with this thing lol.
Here is the firmware archive. First figure out what firmware you have. After power up, Press and hold enter. There should be a 3 digit number displayed (probably 061).
Then, click on the link below. Select your firmware version, then click manual. This outlines all the menus on the radio. Further help can be found in the thread by searching or posting your question

Well, I got my GT3C kit, wired that guy up, flashed the sucker, and spent 4 hours researching and trying to program buttons. For some reason, I cannot seem to make heads or tails out of it. Can't get my 4ws to work how I want just yet

Something just isn't clicking in my noggin about how the settings work. I have to hold ch3 trim forward in order for front steer only and hold it back for rear only... which settings do I use to not have to hold it, but just as a selector? I'll get it eventually, real odd that I haven't yet.
* i should add, that I am following already written guides because everything I tried on my own didnt work.
You have your channel 3 trim switch mapped as a MOmentary function. To make your current setup non momentary
Scroll to REV, press enter-LONG
Scroll to 3, press enter
Leave the screen at 4WS, press enter
Scroll to BNL, press and hold enter
Press back/end afew times
Code:
- Key mapping specific for each model:
> choose menu REV and press ENTER-long
> menu REV will blink
> choose trims (id: 1 2 3 d) or other keys (CH3: C, Back: b, End: E) or
if trim is OFF, then also trim keys (id 1 2 3 d with left/right arrow)
> press ENTER and modify first setting
> press ENTER and modify next setting
> ....

I'd like to use my 3rd channel to turn lights on. But my remote is not showing a 3rd channel, and I have no idea what buttons do what
Scroll to NAME, press and hold Enter
Scroll to C, press enter
Scroll to 3, Press and hold enter
press back/end afew times
Ok now scroll to REV, press and hold Enter
Scroll to C, press enter
Scroll to CH3, press enter
Scroll to MO0, press and hold enter
press back/end afew times
Now the channel 3 button on the handle will turn you lights on and off. (assuming you have a two position light controller connected to channel 3 on the rx)
