Is it the tx or rx that most often fails or either? Does the system have a failsafe that kicks in if the tx or rx fails? I run nitro so I'm concerned with the thought of a runaway. Thanks.

This video shows how to set up the fail safe:

Not sure if this was answered yet, but if you're running a sensorless brushless setup (castle creations products or similar) you should leave your channels both reversed on the radio in order to get the correct steering and 100% throttle when you pull the trigger back. To make the car go the right direction, switch any two of the motor wires where they plug into the ESC. Switching the motor wires will reverse the direction of the motor without changing the signal to the ESC. This should fix your problem. Make sure the system is sonsorless, though. Sensored systems don't like having the motor wires switched around, and will generally have a setting in the ESC itself for motor direction.

Thanks for the link.

I've read that the expo didn't work on these radios a first. Has that been fixed on the newer ones?

I've got two radios, one is working fine, the other don't There is a guy selling upgraded software and upgraded radios

Can anyone tell me the difference between the GR3C/E/F receivers? Will they all work with a GT3B Tx?

EDIT: Also, additional question: I hacked my GT3B with 0.6.1 firmware, but now I can only adjust the steering endpoints in one direction, to the right. When I turn the steering wheel, it doesn't change which way the arrow is pointing. Anybody else experience this?

I have the FLY SKY FS-GT3B, and recently I was able to truely play with my RC at a large parking lot (very large). So, my problem is, at about 200-250 feet my connection to the Tx and Rx are lost. I walk closer to the car and it's back. Range issues.....

Has anyone else experienced this with their FLY SKY FS-GT3B? I am using the receiver that came with the control. And I am controlling a Revo 3.3.

I have done nothing with the firmware or SW on the control.....everything is stock.

My experimenting indicates it's the receiver and not the radio is the range problems. Some receivers (recent ones) I've bought don't have any problems to as much as 75 -90 yards. I mean goo grief how big is the track your racing at!? That's almost a football field in length. Also the Rx antenna placement is very important, don't rap it around anything, have it vertical for at least the last 3 inches, the rest can be horizontal but straight. Like in RC Airplanes, keep the Rx antenna AWAY FROM anything electrical in the car / truck especially the motor and ESC. All give out Rf in all frequencies and can interfere.

These FlySky radios (Tx) are very very good and I like them, but the Rx are a bit circumspect. I think early ones (Rx) were hit n miss.

It looks like I have some trouble with the potentiometer from the throttle trigger from my GT3B . Does somebody knows where I can buy a replacement potentiometer ?

My son has a Flysky GT3B radio, he purchased it 3 months ago. Just recently I bought him rechargeable AA batteries (duracel). AA batts were fully charged before using them. After 2 bash sessions with that Tx and rechargeable batts, the low battery alarm started going off. Voltage showed below 8.4v......remind you, only two bashing sessions around 30 min. each. I swapped the rechargables to regular duracel batts while the others recharged. With a fresh pack of AA, the alarm is still going off and it shows the voltage at around 8v, remind you again, it's a fresh pack of AA. I'm not sure if its the Tx tripping out, or if I did purchase some bad batts. Im going to get another pack to try it again.

Has anyone else experienced this type of issue with this radio?

Folks, I know this is a cheap radio, please be cool....i'm trying to troubleshoot this issue for my son. He has 4 other cars linked to this control, so i do want to try to resolve it without having to go out and purchasing a tx and a few rx's.

Any help would be greatly appreciated!

**no upgrades have been done to the tx....firmware, mods, etc.....it's bone stock.

What are the mah on the rechargeable batteries.

Can you check the voltage with a multimeter?

i'll check the voltage after work. that totally slipped my mind.

It takes a few time for rechargeable take their max amperage, I use 2700mah AA on M11, last at 1hr and a half. 8.5 voltage it starts to giving low batt, it should. I starts at 12 volt, 8.5v they loose efficient volts for TX to operate.

Give a few charge times for rechargeable to be more amperage efficincey. What do you use to charge the batteries. Hopefully you use a charger the go 500ma only. Anything higher will overheat the batteries, heat kills the batteries.

Rechareables low voltage will stop immediately, not like alkaline.Maybe the TX went bonkers of alkaline were bad already Try another set a batteries!! Got me stumped!!!
