GT3B Hack Question and Answer Thread

Try PV0

I've been going through the source code. I don't see how this can be happening especially if it works with the castle esc's....the dig mix is just a proportional constant.

else {
	    // DIG mixing
	    val2 = val;

	    if (menu_DIG_mix < 0)
		// reduce front throttle
		val = (s16)((s32)val * (PPM(500) + DIG_mix) / PPM(500));
	    else if (menu_DIG_mix > 0)
		// reduce rear throttle
		val2 = (s16)((s32)val2 * (PPM(500) - DIG_mix) / PPM(500));

	    if (cm.brake_off) {
		val  = val  * 2 + PPM(500);
		val2 = val2 * 2 + PPM(500);
	    }
	    channel_params(2, channel_speed(val, 2));
	    channel_params(cm.channel_DIG, channel_speed(val2, cm.channel_DIG));
	}

You might want to try a different rx, the one you may have might not be sending signals correctly

Also, try to see if the 4ws mix is acting up too.

Plug in two servo's. See what happens

When I plug two servos, when I dig front, one goes to his end point, when I dig rear, the other servo goes to his end point

how can I have a bad rx ? :roll:

I'll try to find another GT3 near me this week end

This might be a calibration issue.

Recalibrate your radio, then calibrate your esc's.

Oh man...
Losikid YOU'RE THE MAN !

How to explain it? We just calibrate ch1 & 2 not the 3rd

So I just confirmed, I have finally found a direct replacement for the gt3c enter button.

If yours is acting up, send me an email and I can send you a replacement

There has been an issue where the enter button stopped working.

I think you'll like the gt3c"thumbsup"

What is the lowest recommended voltage these can operate off? GT3B with voltage reg mod.

6.5 volts

 

[honchojoe]

6.5 volts

Thanks. I'll set the low voltage alarm to 7v then.

Cheers,

What battery are you going to run?

If you are going to run off a 3S lipo you are going to be too low on that cut off, unless you want to ruin your lipo

Oh gotcha...... yea I saw some trying to fix it or what not. If I have issues I'll get a hold of ya..... is it hard pressed to get that replacement? Just burn it out and burn it back in?

Oh and on this radio I was thinking of running a 4 wire set down through handle out by battery to plug directly into my stm8 this time......... is there room down there in the 3c? And what would be the technical term for that 4 pin plug?

Thanks for any info brother.

Trying to desolder causes issues. I cut them off with flush cutters, clean the pads with solder wick, then solder the new one on. I might do a write up after finals.

Why run wires? Also, you'd have to make room

Just running standard AA for now. Once I change it to a 3S I'll set the alarm to just above the correct lipo cut off voltage.

Gotcha. SAS Just Makin Sure U Weren't Gonna Run The 3S On it"thumbsup"

Well I saw a while back when I looked ya didnt have all the pins etc on your site, figured running a plug down would eliminate a hole in my radio. Haven't had any issues with my Bs now and their hole but here in the nw tend to get pretty wet. Lol.

I think I just screwed the pooch on my order. Hobby people didn't have any and I just tossed out money to gear best......... now I'm reading reviews of ppl who getting jerk ed around by them. My order still has not shipped and keeps saying processing? Donno...... who else you find good and fast that carry the 3c austin?

 

[losikid]

The 3c doesn't really doesn't have a hole like the 3b. Could be sealed with silicone even

Also hobbypartz sells GT3C. They are in the us with pretty quick free shipping.

I have some already done as well. Just not on my site at the moment
