Flysky GT3B RC Car Radio Review - Best cheap transmitter for the money?

[@henrikcsuri]

With moderate soldering skills the Flysky GT3B can be modified to run on 4AAs with swapping out the voltage regulator to a Pololu S7V7F5 (it's also recommended for lower power consumption) and with the software update it can control 8CH and 79 cars. While at it may as well peel off the polarizer from the screen (hold the LCD with your other hand to avoid bending the pins) and stick it to the inside of the screen window to reverse the colors. It's so much easier to see the screen during the day.

[@jeniferdiamond7723]

I watch a video last night were you can just solder on a lipo connector instead and use a cheap 3celm 1500 mah that fits in the easy to remove 8AA tray. Yes that 8AA tray comes out its a piece by itself just take out the bottom screws and seperate the radio halves till you can pop it out. And clip off the pos and neg wires. Then just solder a lipo connector to the wires. Tgey guy in tgat video did show how to use like spong squares and double sided tap to help hold the lipo in. But it fits with being able to close the bottery cover and its lighter and

[@henrikcsuri]

@@jeniferdiamond7723 That's true, but the reason I don't use a LiPO battery, because if I forget to charge it, I can't use the radio, but you can always pickup a pack of AA batteries or even your friends may have extra

We need more people like you

[@cesco_rc]

I have 5 GT3Cs all upgraded to 8 channel. They are going strong for 6 years now and are used a lot. Really good radios. Receivers are very cheap and easy to waterproof. Very light radio in weight, last a long while due to the LiPo battery. I have extra LiPo batteries and you can crawl like forever on them.

Awesome video. I’ve been thinking about doing this for awhile but just haven’t looked into it. I think I have 3 spectrum stx2s and 2 of the Traxxas ones that all came with RTRs. They take up a lot of room. Crazy how that transmitter is cheaper than the STX2. This is my favorite RC channel and I’m subbed to like 20 or so. To the point. No BS. Honest. Useful. Thanks again.

[@jaxattackfishing8496]

The first one I bought was missed wired and had poor solder connections sent it back and got a new one and I will say I am really impressed and really liking mine after failing it in to my car. At first I thought it was junk that was priced to good to be true for what it offered but considering the problems and giving the controller one more chance I’m a believer in this awesome controller and the various hacks you can do with it. No one paid or sponsored me to say this just want to give my honest experience with it as well as stoked to have a legit controller that didn’t break the break

[@Mark_Dee]

Hi. I am using 3 FlySky GT3C all modded to 8 channels with a 12$ 8 channel receiver. Traxxas is only a 4 channel Transmitter. Signal for differentials is splitted in the receiver, because of that you cannot adjust the endpoints of the differential servos. On my FlySky I am using CH1 Steering, CH2 Throttle, CH3 Diff Rear, CH4 Diff Front, CH5 1st/2nd gear, CH6 winch, CH7 and CH8 are for lights. I am using the larger capacity LiPo battery for the GT3C, is sold separately. kind regards Mark

[@RCReviewChannel]

Golden info!!! The Traxxas is indeed only 4 channel. It's such a hack how they put two different servos in one. That's why the front diff has to be locked first. And that's why those servos keep burning up. So when you use the Lipo, is there a voltage protector to prevent damaging the lipo? fc

[@Mark_Dee]

@@RCReviewChannel Hi. The GT3C works only with LiPo. So I think they are protected. I just use the LiPo with the higher capacity.

I bought a Dumbroc ddr350 10ch a few weeks ago, its ok, but i went back to my modded GT3B, im running a 6ch receiver, front winch on ch3, rear winch on ch4 and lights on ch5

[@dillonbesky6196]

Is their any way to switch the braking from reverse brake to forward then brake ?

[@seavee2000]

I have 2 of these Tx with 10 models paired to each one-and will get another to finally convert the other 10 cars still running old AM Futaba gear. Never had any issues,do the lo voltage mod for even lower cutoff threshold,add a ball bearing to the steering wheel and flip the screen filter to give even better contrast in bright sunlight and you are done-easy and cheap mods. You can hack it to make it even more expandable but I haven't felt the need to,and if I want more channels than 3 I prefer a 8-10 channel stick radio which I have for my aircraft. Great radios

[@SpeedSyko]

Wow! 10 models?! That’s great!

[@tw.o.g]

[@roadstar499]

i converted this radio many years ago to use a 3s lipo... other radios can also be converted... but many can only handle a 2s lipo.. or you will fry the radio...ask me how i know...

[@enricodedios3702]

This is the best controller replacement for any RTR kit period.

[@zrca]

I hacked several gt3b and gt3c. Its sometimes hard to programm what you want but is possible. I use one for my scx10 4ch (winch and lights). Programmed one trim to set forward expo in 20% increments. I use the same radio for my micro 4WS crawler. It uses one trim and one button to achieve all 4 modes of 4WS. Also, its easy to mod gt3b to use 3 liion mobile phone batteries instead of 8 AAs.

I just bought one last week. $47. My Airtronics M8 I had years ago had the same amount of adjustments. But it was a $300 radio then. Going to put this on a slash. Might get another one for the other slash. Now I'll pay a little more for a radio for my Losi sct

[@discusdog]

The gt3 c has fixed some of the gt3b issues. Power button switch wire breaking. Steering wheel gets sloppy from plastic wearing. Plus the c has the lipo. Either on can be hacked for fully controllable 8 ch. Kit to do it is like 25 bucks. Rx are like 12 to 14 bucks for a 6ch

Not that I don't WANT to spend $100-200.... I CAN'T anymore. 😭 I ALWAYS ran Futaba, but can't now... Having the FlySky GT3B, I concur with you and several others! I've done the 3S Lipo conversion - I highly recommend doing that! 👍👍 There's several cool Hacks for this Radio. It's been a favorite for awhile. Also, Thingiverse has 3D Printed Files for a "one hand" Thumbwheel for it. Carmine ✈🚂🚙

[@CarminesRCTipsandTricks]

For Crawlers, I highly recommend adding at least 35% Expo to the Throttle. 😉 NOTE: Expo is REVERSED on these! Meaning, set it to NEGATIVE -35% Expo, or else your Throttle will be even MORE twitchy!

[@yinghaotan5884]

Radiolink RC6GS/RC4GS has functuon of Subsidiary ID ( ID seed), does GT3C has it? ID seed explanation from Radiolink is when boat1 still has minimal power, while using boat2 to rescue boat1 ,transmitter controls two receiver at the same time. In this case, radiolink transmitter is able to only communicate with boat2, make it easier to rescue boat1.

[@thepaddychannel]

I got the Flysky GT3B as the stock remote for my King Motor 1/5th buggy then got some extra receivers for my other cars and have them all set up on the one controller. Just remember to turn off the car before swapping to the next or you will have both cars running at the same time. I thought just change profiles would be OK, but very quickly found out I was wrong…

Go into the radio's settings and reverse channel 2 (throttle) from norm/normal or rev/reverse to rev (if it was on norm) or to norm (if it was on rev).. same can be done on ANY channels on your radio (it's called "channel reversing" btw). I hope it helps u

Can anyone please explain what is wrong with mine iv just bought it but the brake does not work on my truck now i let go of the trigger and it just keeps rolling even when i push the trigger forward

[@TraxxasGemini3.3]

It sounds like your Brake Rate is set to 0%, increase it (your brake rate needs to be set above 0% to make the brakes function as Brake Rate or Brake End Point Adjustment sets the overall travel on the brakes side.. on 0% your model will "free roll" having no brakes at all .. 100% will mean when u move throttle fully away from the throttle/gas side u will be at maximum brake travel depending on your model's linkages and settings.. same also applies for steering rate/ end point adjustment/ travel, and your 3rd channel and other controls set on your radio u can control.. total brake power is all about personal preference as well as needs to be set according to your model as some can take full travel on the radio while others need less.. your servos should NEVER hiss nor make noise when at the ends of their limits, if they do reduce overall travel until the servos don't make any extra noise it'll keep them happy being less stressed and u won't break your linkages or worse damage the servos.. proper setup on your servos ensure u get all the travel u need without adding excess strain/wear and keeps u from breaking parts... )

Hi! I use FlySky GT5 (with FS-BS6 receiver). 6 channels, 4xAA batteries or LiPo with JST plug, screen, 20 models memory, but I think it is $70 or even more. It has all the settings as GT3B and some additional goodies like a gyroscope (useless for crawler), but it has a crawler mode too. I would buy GT3B if I had known about "hacking". I thought it was a 3CH because many sellers on eBay/AliExpress wrote it is 3CH transmitter (not just the receiver).

Great review, dude. 😊 I have 2 of the FlySky FS-GT3C (one mine and the other is my father's). I can't confirm in what it's better than this one or even if it is... (Like another person commented.) But it's really great and I could go really far with it while doing FPV. (I don't know why, but RC doesn't make sense anymore to me if it's not with FPV. LOL) Anyway, I know that DasMikro (DasMykro? I don't remember) sells a version on Banggood of the radio already hacked and with LOTS of other buttons, knobs and so on. There's another FlySky radio as well, I don't remember the name, which looks like a smartphone screen in the top and it's FULLY programmable. Even things like failsafe and so on! A friend of mine from the US has one and loves it! 😊

[@zeoncrux]

Are the receivers of the flysky waterproof?

[@roadstar499]

no

[@josbarhorst]

I noticed you said expo effects steering on speed? How does that work? My experiance is expo effects the signal from linear to curved?

[@RCReviewChannel]

Actually not. We're thinking of channel mixing. Expo Setting is slowing down the initial response to steering input on the controller wheel then increasing sensitivity at the end of the travel. This makes the vehicle easier to control (especially at high speed) since the driver is less likely to oversteer. And then at the end, the response is sped up so the driver can have full steering range. It also balances out the steering deficiencies of a servo since it travels at an arc and doesn't move the steering as much at the end of the travel. Exponential setting is usually set in negative values. -50% expo means less sensitive by 50 at the beginning of the travel.

[@signaturedean]

Greetings from Australia :) i just got a MJX Hyper Go and had this controller given to me, working better than the RTR of course but having trouble getting reverse to work.
