Hooked up a new Fly-Sky FS -GT3B. Used the Reciever that came with the radio. Everything checked out fine, Steering, Throttle, 3rd channel kill switch. However, I did not test turning off the transmitter with the cars electronics on.- this would have been a dead giveaway that the something was wrong with the transmitter. The car lost its signal, went wide open. Gald the hsn was rich to the point of not reving out- No steering-throttle-no 3rd channel. All i could do was watch it head across the field and clip a big concrete barrier. Opon returning to the shop I thought- I should have just turned the transmitter off- Well, I tested this on the work bench. This made the throttle go wide open. I tried binding up the supplied reciever and 3 others to the suspect transmitter- No cigar. No bind occured. Hooked up the old transmitter, Everything checked out fine- When the transmitters power was turned off with the cars electronics on, the throttle servo did not go wot. kill switch operated as intended also.- Its gotta be a bad transmitter- What do you folks think?
 
I could be wrong about the loss of signal- If this was the case, the kill switch should have shut off the cars ignition?
 
Sad to see your kit in pieces!! loss of signal should have killed it in any cases. I almost ordered a GT3B from nitroRCX lastnight but DDM won my cash I will stick with the stock TX/RX for now I know it works. You know that if hitting solid objects becomes a sport.. I will have tough competition with you around lol.
 
yep, it was a day. I did fire up the other car and ran it around for a while. The XBs parts did not get torn off- the photo was after unbolting the front end. Darn, if the xb would have to the left just about 3 or 4 inches, it would have launched into a big brush pile. Thats a soft crash. Will phone Hobby Partz monday morning and be diplomatic explaining - try to get a r-a # for a replacement. Yea, the darned thing went about the lengith of a football field- before kissing the concrete!! not a thing i could do either-- I have read stories on the hpisite about cars going tru a scoccer match out of control. geezzzss!!
 
Sux man!

I've never seen that happen. The gt3b is a great unit.

Check to see if the plugs were in right. Black to the out side.

I alway bench test the radio first and get the EPAs set before I run it. I also make sure the kill switch can do its job. If I remember right at least one of the channels had to be reversed.

Also that POS failsafe that comes with the car can not be used. The FS has a built in one. That needs to be set or disabled. That is what most likely sent it full throttle.

Yes if you shut off the TX. it maybe did not loose signal. The RX was just doing the wrong thing.
 
Yes, these cars have the killer bee. On the xb, both the throttle and steering have to be reversed. The 3rd channel is normal. All the adjustments were set to a tee. Never use the exp on any channel. I started off by matching the settings on the display the same as what is on the old transmitter- then fine tuned steering-throttle- 3rd channel.- The new tx -when bench tested, could not bind up 3 diffrent rx-es. -it did bind before the xb was driven. the killer bee operated correctly also. All the wiring to the bee and the rx were correct.- After benching the xb, I bound up a rx to the old tx- worked as always- perfectly. Not to be defeated- bummed by this- I fired up the other car on the same old tx as usual and had a roaring good time!! As odd as it sounds-- Everything points to a bad tx- the new one. Lucky the hsn was way to rich- it could have been going lots faster. If the mighty xb just would have hung a wee bit more to the left- it would have hit a gently slopeing bank- about 2 foot tall and augered into the bushes!! lol. oh well- This is why i really do notlike non r-c ers too close- they do not understand murphys law the way r-c ers do.
 
Oh, forgot to say r-c dad, I never tried to shut the tx off- just hit the 3rd channel- I sorta froze up i suppose. I tried shutting off the tx after the car was toted back to the shop- went wide open.- no adjustment would change this.- good chance its either loose -cold solder joint- bad solid state- or even a bit of loose solder floating around inside the new tx.--could be anything. Will call Hobby Partz Monday and repeat this on the phone- see bout getting a r-a #.
 
I kinda figured you did more than just plug and play. I just wanted you to clarify the steps you took setting it up. Not really for my sake, but for the readers.

Something did go wrong between the TX & RX or the killer bee would have taken over.

Again sorry for your bad day.

Did you set the fail safe?

I don't have that radio, but if the fail was set backwards, like the reverse switch on the servo...it's acting WOT instead of brake?
 
Checking out recievers on Fly-Sky.

O.K. folks. For starters my real title is David. Last is not Numan either. I had a bit of trouble the other day with the xb. Radio troubles. You should all take a few moments of time and test this. It could save some choice words later. Firstly, the car-truck- does not have to be started. Turn on the transmitter. Turn on the power switch on the car. Look closely at the throttle servo. Turn off the transmitters power switch. What does the throttle do? -- O.K. I have 3 Fly-Sky recievers. Each one of these behaves diffrently with this simple test.-RX# 1 -the throttle stays motionless- the same place as when it had throttle applied. RX# 2 went wide open throttle. RX# 3 went full brake- full to the point of actually flexing the servo mounts. I do have the rx that came with the redcat when i bought the car. I will try that one later and post results.- I am guessing that what happened to me and the car was that the radio system lost its signal- either no or off frequency transmitter signal, or-- the reciever failed to pick up the transmitters signal. The kill switch -throttle- steering went dead- could only watch it go by-by!! This was with the above mentioned #2 reciever- In bench testing today, the reverse- normal feature had zero effect on these results- As for the 3rd channel- it makes no diff- its either in circut or out of circut.-- Recievers are cheap to buy- major front end parts are not- shocks-shock tower- didd- diff housing- a-arms- steering links- ect ect---
 
None of this is really complex. just lots of varables. The fly-sky radios sorta hop around- the frequencys that is- There are so many devices in the gigaherz range - gotta wonder if it locked on - or was interfered by heck, who knows?- cell phone- cell tower- I have seen posts about the Fl-Sky being turned on with diffrent brands of radios around and causing glitches.- Nothing is 100% perfect. Murphys law ya know? The above post- was with 2 diffrent Fly-Sky transmitters- just saying--
 
I had some similar servo behavior when the TX was not on. This actually waisted a stock throttle servo instantaneously during first power up. I disabled the failsafe in the RX and that fixed the issue. There are YouTube vids on setting and disabling the failsafe feature.
 
hi. did this happen with the stock radio that comes with the cats? All my issues were with the Fly-Sky FS-GT3B 3 channel. I have never used the radio that came with the redcat. I did look @ the reciever this early evening- its a 3 channel- I will see if it will bind up to the GT3b soon- just for hecks and giggles-- actually, it looks as if its a rebranded Fly-Sky.-- see no reason fo it to not operate. yep- i use a killer bee kill switch in one car- and a switch bought from an electronics dealer in Michigan- just cut a circut trace, make a window- hole with a lexan cover on the top of the rx box on the car- same as the old style killer bee for 20 bucks if memory is correct.
 
yep, the led on the homemade fail safe is very bright- easy to see in full sunlight- its soldered into the p-c board- thats what the window on the rx box was for--

Mine happened on my Gt3b. The stock Redcat TX/RX are rebadged Flysky. I've actually been able to rebind the factory RX to the Gt3b.
