GT3B Hack Question and Answer Thread

Ok. So I set up the controller like the YouTube info said too. And as it's powered up, the winch starts moving and I can't control it or reverse it. What am I doing wrong? It's a 3racing winch. Thanks

That is the correct the settings for the radio. So you're probably doing something else wrong. I need more info to help

Alright. So I hooked up a spare servo on channel 3 and now I'm able to control it with the ch3 trim buttons. Unfortunately, now my servo in channel 1 is not responding. If I switch to a different model, the ch1 servo works again and the ch3 doesn't. I don't know how I did that. Lol

Should I do the r+mod and start over?
 
Hey guys I've searched and can't really find the answer I need. My GT3B is hacked and I have the 3rd channel set for the a winch. I want to add a HeyOk light controller and to be able to use the 3rd button on the controller to turn the lights on and off. Not sure how to make this happen.

You'll need to get a 6ch rx

Change your channels to 4 in the long-name menu

Do the same thing you did for the winch but choose C as the switch and ch4 as the function.

Also you'll probably BNL instead of BMO

Thanks losikid,

I have the 6ch rx, that's seems pretty straight forward I'll give it a shot!

BNL - BMO ???


Thanks John
 
Got a question for those in the know. My gt3c came with a 3ch receiver. If you do the hack can you use the 4th port as an additional channel? It's labeled vcc

No, thats a BEC or external battery port.

You need to get the 6 channel receiver or the 8 channel.

If you can wait for shipping, they are quite cheap.

Banggood: 6 Channel $7.61 free shipping FS-R6B FlySky 2.4Ghz 6CH receiver for RC FS-CT6B TH9x - US$7.61

8 Channel $10.78 FlySky FS-R9B 8Ch 2.4Ghz RC Receiver for TH9X Transmiter - US$10.78


For those who want an extra 3 channel (don;t know why when you can get a 6 channel and just use 3) $6.45 Flysky Receiver for GT2/GT2B/GT3/GT3B/GT3C/T6/CT6B/GR3E/TH9X Transmitter - US$6.45


The 6 channel is a real bargain. The only problem is the Shipping time. Banggood (liuke most of the Chnese Vendors) use "Slo Wei Shipping"


They will post it quickly, but figure at least 10 days to 2 weeks.

But worth is, I have ordered quite a few times from this vendor and have not had any issues except a minor one, and they resolved it quickly with a refund. So reasonable customer service and good prices.

So can I plug my bec in the vcc port and just remove the red wire on my speed controller in ch2

Depends on your voltage setting on the BEC. The Rx can be powered by any source with the correct voltage. The whole idea is to make sure that multiple voltage SOURCES aren't interconnected.

The Center pins in the RX are all interconnected. So you can power the RX from the VCC port, or any of the channel ports. Since most ESC have a built in BEC, if you use either a battery or BEC connected to the VCC port, all other red wires from ESC's that have built in BEC should be disconnected.

The Flysky RX is not made for over 6.5V as far as I can make out from the literature. So if your BEC is 6.5 V or less, than you can use it to power the RX.

Hope that wasn't too confusing.

Not confusing at all. My only question is how can you run a high voltage servo then. If all center pins are connected then whatever you run in ch3 has to run at 7.4v as well. Guess I need to look into the Holmes Hobbies direct servo powering lead

If you have a 2s lipo, then run the red pin on the servo right to battery +. You can run a servo off the the battery, the receiver off the esc and lights off a separate bec. The trick is to keep each red wire on its own circuit.

The only place wiring is common connected is the red and black on the receiver....so by not connecting red to the receiver, each device with a separate red wire can have its own power source.

I picked up a slightly used gt3c already hacked. I'm having some glitching issues using flysky 3 and 6 channel receivers as well as older axial. All of them will glitch into reverse semi randomly. It seems to happen more often if I'm off or barely on the throttle turning right. At first I figured it was an issue with my bouncers steel chassis and interference but then I ran my crawler on this radio rather than my old faithful non hacked gt3b. It does the same damned thing. :lol:


I don't seem to have a 4 pin port on the radio to download newer firmware, I'm guessing I need to do some work eh?

Make sure both the radio and esc is calibrated (Calibrate the radio first).

If that doesn't work I can tell you how to open up the dead zone

Esc's were calibrated to the radio first thing since the channel 2 had a different dead zone. If I remember right both esc's were roughly 20% in reverse prior to calibration.

How would I go about calibrating the radio? I need to download the directions off your site when I have time to spend learning wtf I got myself into. :lol:
