GT3B Hack Question and Answer Thread

A majority of rx's aren't hv. Run them all at 5-6v to be safe. And easy practice is always let the esc power the rx (that's all most are good for anyway) and power the devices with bec's.

Don't forget to star ground it all back to the rx "thumbsup"
 
Ah, now I see that my Tekin FXR's built in BEC is rated at 6v, so I can run it off the ESC. Cool.

What do you mean "star ground"?

The idea is to ground everything back as close as possible to the source, in this case the internal bec of the esc.

When you say ground I keep thinking of electrically grounding something.
Do you just mean to keep everything close to the BEC? In other words, don't run long wires?

Sorry if I'm being dense here...

Naturally one would want wires as short as needed. Placing things physically closer and grounding are two different things. Yes electrically ground all your devices back to the rx, which in my scenario is where the esc's bec is... Which is the main power source for the rx and your electrical system, the lipo pack.
 
hey losikid I have a gt3b that I hacked myself and it worked great for about 8 months until one day I left it on for a couple days till the batteries died in it. now it has pixels that don't work anymore and it's getting worse to the point that I can't read the screen anymore. any suggestions?

Thats odd...but only thing you could do is replace the screen. They can be ordered from china fairly cheap, but you need to be competent with a soldering and desoldering techniques to install it.
 
would it be worth it to just buy a gt3c and hack it? I'm not into any crawlers or scalers right now but looking to get a scx10 soon

I prefer the gt3c over the gt3b....

And if the latest revision of the gt3c fixes the power button issue then they won't have any faults besides the firmware. From what i've seen, the 3c had a better build quality, is lighter, and better ergonomics (imo)

I have tried the directions from post 3008 numerous times. I cant figure it out...

Elaborate, i'm pretty good at filling in gaps but i can't fill in gaping holes.

directions from 3008 was posted to solve an issue not as a template....so i'm not sure what you're trying todo.

More information the better
