GT3B Hack kit- Pre-order

[losikid]

Ok so i need atleast 8 pre-orders. What this will do is allow channel mapping to the trim and dual rate switches/buttons, up to 6 channels, dual esc mixing, 4ws mixing (crab, mix, front, rear, etc)

This will include a modified programmer
usb cord
4 pin gold plated header
12" 4 pin female to female extension
Good install Instructions

For $22 + shipping. first class is $3 priority is $5 for domestic mail.


I'd like to get a 10 kits pre-ordered. PM me to order.

This kit will require a whole 4 simple solder joints, i'll even make instructions on how to solder those for those afraid to solder circuit boards...but its not hard,

This is the manual with the firmware...i'll make a better one but if you want a peek here you go

Does this include a 3 pos switch or is it part of the programming? Making the switch momentary.

It does not include the switch, it will use one already on the radio...like the ch 3 trim, d/r, or the st, th trim buttons.

I will sell the switch at later time, but my supplier will be out of stock for awhile. and i still have to test it.

Also for the pre-order, i won't have indepth install instructions, because i can't find my camera but it's real simple,

Pull the screws
open the case
Solder on the header
Route the extension through the handle, out the batt box
screw it back together


Here's some pics thanks to QuangVuong

This is where the header needs to be soldered



The back side




And this is the orientation it needs to be plugged in

[losikid]

Ok well i didn't realize how tight it was on top, programmer cord won't be comming out of batt box...i have afew other idea's i'm going to try out.

Worst case scenario, you'll have to pull a few screws every time you want to re-program it (new firmware is release)

Either way price is the same as my parts list isn't changed...but i think i can keep it from having to undo a few screws to re-program...i will test those idea's soon.

Will this reprogram allow for the exponential to function properly?

Can you program the backlight to stay on longer?

Is the modified programmer the special circuit board you need to reflash the transmitter?

I am very interested in this. The thread on rctech started it, but I was't tech savy enough to figure out what the heck to do. But if this is as simple as it sounds I'm in.

Yes this will fix expo, trim, adjustable backlight, a lot more. It's the same firmware from rctech...it'll just include all the proper stuff to do it, instead of a home brew setup

The modified programmer is just the stm8s programmer with a few solder/jumper points removed.

And now that I think about it, the 4 solder joints arnt required, just put in the header, apply sideways pressure and hit program.

Im out then, I will wait till the 3pos switch is ready. The 3pos switch is the only beef I have with the radio.

I believe he is saying the rocker switches above the 3rd channel button will be momentary 3 position switches


My question is will.there be endpoint on these other channels?

Yep epa's on all other channels

You can map channel 3 to use the ch3 trim or d/r 3 position switch, i think (i'd have to check) that the ch 3 button can cycle between positions, or you can use the ch1or2 trim buttons...which will all give 3 pos control.

If you install the 6 ch position, you can map a aux ch to each set of trim buttons/ switches and have 4 channels with 3 position capability plus go and steer.

and don't forget the mixing features. For $60 investment, it is a very advance radio, the 4pl has it in little things, like ease of programabilty, probably alittle more ergonomic, stuff like that. but costs alot more, and extra rx's don't cost 10 bucks.

[losikid]

Alright guys looks like i need atleast 4 more pre-orders

[sloppy]

with this mod will the 3 channel RX not work anymore?? I dont really care just curios..

Yes it will work, but only 3 channels

And there is a 3 channel firmware and a 6 channel firmware

[losikid]

Ok so you will need to modify the case just alittle, and its real simple. A pair of snips and needle nose will do it, taking about a 1/8"x 3/4" chunck out near the antenna, basically just one of the grooves...This is an optional step, but much easier than unscrewing the case each time you want to program.

So far tools to install,

Philips screw driver
Soldering iron

Optional tools is
Small flat head
Hot glue gun (w/ glue)
snips
Needle nose


I can probably install the kit 10 minutes, for someone reading directions and carefully doing it...about 30 minutes.

[losikid]

So I tallyed up final prices, and since i modified a few things from my original plan, price will go up slightly, all pre-orders will remain same price, about 5% off from what they'll sell for after pre-orders.

[slowtocrawl]

so if i have the 3rd channel mapped to the d/r button will i have to hold the button for dig or will it work like my dx3e where i push it up for dig then have to push down one time to go back to 4wd
