GT3B Hack Question and Answer Thread

[Charlie-III]

That suits me fine. Anything on the top panel would be great.

I hope I can get to the point where I can understand how to do these things for myself. Are you there yet, Charlie?

I'm popping in.
I'm not the programming Guru. I'm messing with my dual ESC program on the GT3B (older firmware) so I can post options for others.8)

Sorry, Austin, I'm not getting anywhere.
I guess I need a step by step guide for two items...

First Item:
CH4 to be a two position channel that toggles when I push the END button.


Second Item:
CH5 to be a three position channel for winch control. Momentary control by pushing the left or right steering trim to make the winch wind in or out.

Thanks in advance,
Al

OK, i'll try and get you something to work with in the next day or two...do you want the 2 position to be 0, 100, or -100,100 (i'm assuming non momentary)? and do you want it the end button or one of the th trim buttons?

I would like the two position to be non momentary from -100 to 100. I would like it to operate from the End button.

My assumption is that once I see a couple of these procedures that I will be able to easily change the button that operates the command and be able to change the "swing" (0, 100, or -100,100).

Maybe once I see better how these things are created, I can make a flow chart for doing these setups.

Thanks!

The Manual has flow chart...then info on each step in a list below it"thumbsup"

steps of setting of keys (C b E 1< 1> 2< 2> 3< 3> d< d>):
	- sequence:
	  function -> momentary -> reverse -> prev_val -> function_long -> reverse_long -> prev_val_long

I'll try and get something written tonight or tomorrow , abit shy on time right now

I was actually feeling ambitious the other day and started looking at one of the manuals and was going to load it into word and do the indenting so it was a nice outline format. Then my pre-schooler decided he wanted to go outside and play so that got put aside.

Hi everyone

I have just installed this firmware and am very confused on how the setup the 3 switches on the grip.

My application is a boat.

What I would like to do is set CH3 TRIM to lower the trimtabs by a certain amount every time I clicked it, or to just lower until the button is released. Then to bring them all the way back up by pressing CH3.

Your comments would be most helpful.

Regards

Fred

Hi fred, i'd be happy to help

Are you wanting to control channel 3 or the channel 3 trim via a switch? which switch?

 

[FredZ]

Hi Losikid

Thanks for the reply.

On the grip there are 2 trims and a switch.

I want D/R to do what it did ex-factory. Or can be dissabled all together, I don't really need it for my boat.
I would like CH3 TRIM to move the trim tabs down when pressed, Not all the way, but say 20% per click when I push the button away from me with my thumb. Then to do the opposite when I pull the button with my thumb.
I would like CH3 switch to simply lift the tabs. This is a quick get up and go out of a corner.

By sheer fluke and playing I have managed to get CH3 TRIM to work as desired, I just can't work out how to get CH3 switch to work. Don't ask me how I managed to get CH3 TRIM to work as I couldn't tell you (grin). I just played until it did. I figured if I played I wasn't going to do much harm, and if I really fouled it up I could simply reset the entire thing again and start over.

I look forward to your comments.

Regards

Fred

Sounds almost like you want it set-up similar to a dig switch/dual ESC with proportional.
The template I use for dual ESC is the ch-3 trim is a momentary +/-100%, the DR is set to 5% steps for each push (in either direction).

May be this info will guide LosiKid or others to give you programming. I'm at work so I can't help right now.

Are you using the most recent firmware? That makes a difference, I'm using an older version & the programming is different.

 

[losikid]

heyok, to set the END button to control ch4 as a -100,100 momentary do this

Long click REV
scroll to E, enter
Scroll to CH4, enter
MO0
RE0
PV0

If you want it 0,100 it needs to be PV1, if you want -100,0 you want RE1 and PV1

The ch 5 winch

Is

Long click REV
Scroll to 1, enter
scroll to ch5, enter
scroll to BMO, Long enter

Once again, are you trying to control the 3rd channel trim or the 3rd channel?

and which firmware version are you using (0.4.1 or 0.6.1)

 

[FredZ]

OK, with the 3 channel firmware version 041.

Reading the designations printed next to the switches on the radio itself.

CH3 TRIM to move 20% down when each time it is pushed, and -20% up when pulled. I have that working. I may need to reverse this if the tabs are backward.

CH3 switch to only lift the trim tabs. So no matter where the tabs are, they only go to 100% if the button is pressed. I may need to reverse this if it is backward and have the tabs go to -100%. Note that I don't want to tabs to go down when pressed, only up. This is a one way action only.

If I can't get CH3 switch to function as desired I am happy enough with how the CH3 TRIM is functioning.

I hope this clarifies what I want to do and what I have to do it with.

If I need to installed 6 or 8 channel firmware please let me know. But remember, I am still only working with a 3 channel receiver.

Regards

Fred

Thank you, Sir!

The ch 5 winch

Is

Long click REV
Scroll to 1, enter
scroll to ch5, enter
scroll to BMO, Long enter

 

[FredZ]

Hello heyok

With the 3 channel firmware installed you cannot sellect any channel greater than 3 in any mode.

Hence I installed the 8 channel firmware and did as described.

The first thing I noticed was that in the second set of instructions

The ch 5 winch

Is

Long click REV
Scroll to 1, enter
scroll to ch5, enter
scroll to BMO, Long enter

BMO doesn't exist.

Remember, I am only using a 3 channel receiver. 1=steer, 2=throttle and 3=trim tabs

I have CH3 TRIM working as desired.

I would like CH3 switch on the grip to over ride the CH3 TRIM if it is presseed and bring the tabs up. No other function.

It may be helpfull if someone could provide me with the designations for all the switches for the radio and I should be able to work it out from there. It seems all the functions are mentioned but not the designations in the documentation. Thats unless I am confused about how the documentation is referenced.

Regards

Fred

What i'm asking is are you trying to operate the entire channel 3 range or just the trim range...I don't care what the switch says, i'm wondering what your trying to operate as i don't have a boat to know...last guy i helkped setup for a boat he wanted the trim setup but it sounds like you want the entire range but i need to know for sure as a 20 % step can either be 20% over the entire channel or if its a trim it only be a 2% step over the entire channel

Actually, just tell me did you choose ch3 or st3 when you setup the slider switch?

 

[FredZ]

Sorry, now I understand what you are asking.

Not sure how to answer it so I will describe what I have, and what I would like

When I first turn the radio on the trim tabs are at -100%.
As I push the CH3 TRIM it moves 20%. so it takes 5 movements to get to neutral, then 5 to get to 100%. Then the same is reversed as I pull the CH3 TRIM. I have also set it to RPT so I can hold the direction and it will cycle till it reaches the end of movement depending on the direction I have selected.

So currently CH3 in the firmware is set to:
REV long press
3
CH3
RPT
20%
NOR
NOO

Currently the CH3 switch does nothing.
I would like it to move the tabs to -100% regardless of where the tabs are in the range.

Fred

So what you need todo is

Long click REV
scroll to C, enter
scroll to C3R, long enter


your done

 

[FredZ]

Awsome, thank you.

Whilst C3R seemed to center channel 3 I did manage to work out something that was useful.

C
CH3
SWI
NOR
PRV
CH3
NOR
PRV

This lifts the tabs when clicked, then returns them to the prevcious position when clicked again. An operation I can use well as I can set the tabs to any given condition during the day and simply lift them when not needed and return them when needed.

Now I am waiting for more receivers to arrive so I can run dual receivers in my 72" boat. Something that proves very easy with this radio given that the receivers bind with the radio and not the model.

I note in the manual that the keys are noted and listed, but doesn't tell you what actual button those keys are assinged to.

Thanks for all your patience to those who helped.

Fred

 

[CAIRN]

Amazing stuff Losikid.

Installed the kit yesterday, loaded the software and then the firmware. Remapped and calibrated buttons then updated individual model settings. Even set the voltage alarm. Easily THE BEST $25 ever spent on an RC upgrade.

If ever there's a chance, the first round is on me. Thank you. "thumbsup"

Can you tell me more about running dual receivers? Is this for noise immunity/reliability? How does this work?
