I already wrote it. This will work only with support in firmware.
In hardware there is resistor somewhere connected between CH3 button and +5V. Another pin of CH3 button is conneted to GND. And that pin of CH3 button with resistor is connected to microcontroller to ADC pin, so it will be possible to use it in new firmware (after writing code for it).

Well, I have the 3 Racing kit and the R2 flashing kit. They both work with the receivers.

This is quite interesting, QuangVuong. I have dealed a lot in the past with this problem. From what I know and also have tested for myself, the Flysky 3ch RX (Flysky FS-GR3C) does not work or works very oddly with these LED light kits:
- 3Racing LED Light System
- Ultra Bright LED Indicator Signal Light System (from R2)
- GT POWER Car LED Light System 2.0
- HobbyPro 364 LED System
It is because these light kits are electronically the same, clones. They are suitable for RXs which output signal bandwidth is between 5 to 20ms. 20 to 22ms is a typical output signal bandwith for most common RXs, including the Flysky 3ch. Really, I tested a lot of those LED light kits, so I am surprised, that yours work.

Anyway, if you are looking for a very good LED ligth system (those above are crap), look at this one: http://www.bel-shop.eu/detail909.html There is an english manual available. It is worth those cca 35 bucks.

Yeah, I know... somehow this thread expanded a little in 2 last months

The way you use the STM8S kit impacts the type of programming cable. When you power the radio from USB, you need a 4-wire cable. When you power the radio from its batteries, you need a 3-wire cable.
I do not know for sure now, has anyone tested a 2-wire cable, w/o the RST?

Default jr charger

This way it's more like a trickle charger. If am in a hurry I could bump it up to 1 amp but don't like to, it takes about 1.5-2hrs at this rate.
could i just swap the wires around inside the tx on the charging plug so a jr or spectrum unit could be used to charge nimh ? or futaba and jr plugs diff size?

It is useless to have the FW at this time. If your kit is really prepared for GT3B flashing you'll see only when the radio arrives and you connect it to the kit

So I read back through several pages and can't seem to find the post where someone was offering to part-out a "bricked" radio from a soldering job that went bad. I need the potentiometer from the steering.
