Just bustin.....

GOT IT!!

Turns out first receiver was bad , and the second one was bad , (reason for thinking it was another problem) swapped in a third and had it working within minutes...

Thanks everybody, sucks we had to chase our tail for so long.


now , how can i get this thing to run a super? aside from getting a 6ch

, i find it weird that two in a row had that issue, but anything is possible...

What all do you want to run and how?

Great that you got it fixed.

Sorry you had 2 bad RX's. Are these new? Where did you get them from? Maybe you can get them replaced under warranty?

At least they're cheap RX's, not $60-$80 like a Futaba.

As to the super, yes, you can get dual ESC's, 4WS, etc.

[Random Hero]

you can use frsky rxs with futaba or just use futaba rxs heck its only money you can make more..

no big deal they were a season old, one was de-cased, the other not, bought them from hobbypartz , hadn't thought about replacement as they are so cheap. just know to buy them by the handfull.

Yeah it doesn't make much sense but i tested it out again this morning and they were both toast.

As for the super ,it will have Dual escs , rear steer,

dig with d/r and rear steer with trim. probably no mixing for now.

On the XR , how can I set up the dig to turn off when you let go rather than having to switch back to center from the front/rear dig, and is there a way to switch the position of the mixing and the dig?

Thanks Losikid for taking the time to figure all this crap out , it's mindbottleing.

There are 2 posted dual ESC dig templates. One is momentary, the other is locked.

On page-1 of this thread is the momentary template for dual ESC's posted by LosiKid.
Somewhere recent, I posted a template for a locked dig on dual ESC's.

Both are for 0.4.x TX firmware and below.

Keep in mind, the locked dig will return you to "0" proportional when you go back to 4wd. This is a programming issue.
In the momentary dig, you go back to the last proportional %.

Not that I know of. May be true, but I highly doubt it.

BTW, my printer is broken, thus I can't "make more money".

[nappahdog]

got momentary

FR sky (not flysky) does have fasst compatible recievers.

Cool, so you're working now?

Bind question:
I have the GT3C, hacked 0.6.1 and setup working great with my 4ws crawler, setup on channel 0.
I bought another rx for my scaler, put the bind plug in, the the whole binding process with the tx on channel 1, the flashing light turned solid and I thought I was good to go.

Now with the tx on channel 1 I get nothing, it's dead. I switch it back to channel 0 and it works. Except that's the channel my other crawler is on so that's obviously not going to work.

How do I bind the new rx to channel 1 or some other channel than 0 so I can set trims, etc separately for my other rigs?

[Charlie-III]

Channel "0" or model "0"?

I would think you would want to create a new model, then bind an additional RX to the model (I believe the new model must be selected before the bind process).
This would allow switching models, powering the rig & it works as intended.

LosiKid may chime in, but maybe re-bind the original RX to model "0", create a new model location and bind the new RX to that.

I may have missed your point, thus my advance apologies.

[bbaxter51]

I misspoke. I meant model, not channel.

How do I create a new model? I just moved the wheel to Model 1, and renamed it. Then powered off the tx in model 1 and did the bind process. It seems to only bind to model 0.

EDIT: I just plugged batteries into both the crawler and scaler and with Model 0 selected, I can drive both of them around at the same time. Not sure if that matters or not.

i have a peculiar problem.

i was flashing a turnigy GTX3 for a friend of mine .

all went fine until after the flash that the transmitter wouldn't turn of anymore.

checked all the usual suspects, battery works , regulator works, cable ok .

after a lot of brain storming i've found that the chip on the board (GT3b rev 3)
says STM8S105K4



but i've flashed as per instructions with the stm software set to STM8S105X6 mode, when i've set it to the STM8S105X4 which is the same as the chip and loaded the last firmware it said that most of it is out of range, i've flashed the firmware anyway.

now the unit turns on but does not work , but at least the display shows something.

so now to get it work i would need an original untouched firmware, preferably from a GTX3 , but any GT3b would probably work.

in hindsight i should have dumped the original firmware first.

so if anyone can help , it would be much appreciated

UPDATE: i've successfully flashed ver1 of the firmware , all the rest of the firmwares just reports Line 522 out of memory range

Ok, I think I figured it out...

It was binding on Model 1, I just had to go setup all the mapping again, set the trims, calibrate the throttle, etc.

Now for the strange part. Both my crawler and my scaler will work on model 0 or 1, it just maps the buttons and trims for the model selected. So I can drive my 4ws buggy around with my scaler trims and modes, just everything is WAY out of whack. Strange it works that way, maybe it's designed that way. I just need to be mindful of what model I'm in before stabbing the throttle on either rig. ( fwd and rev are opposite on both rigs)

[cartronicshn]

Don't worry, that's the way it's supposed to work , it happened to me also, as I was used to my dx3r which only allows one model at a time

[MiniMorris]

So what happens if I leave transmitter on with a lipo. will I discharge till it catches on fire or will radio shut off at a certain voltage because of voltage reg. Mod? Thanks.

[Meatwad]

Radio starts beeping at 9v. At which point its time to pull your pack and charge it.

+1...unless you set a different LV alarm point.

There is no "auto shut-off", so yes, you'll kill the pack if you leave the TX on. It doesn't matter what battery type you are using.

[motakitty]

And dont forget to unplug your pack if youre using lipo even if its off
