Transmitter help!

I’ve got the FlySky fs-i6x transmitter, and the recieve it comes with.

channels 1 and 2 are the right and left hand motors, yet they seem to behave haphazardly,

sometimes they work, I move the right gimbal forward, and both wheels rotate forwards. sometimes I’ll move the right gimbal forward and only the left wheel will go forwards, and the right remains stationary, if I release the gimbal and try again, they both move correctly, it seems like it doesn’t always take instructions first time around.

im sure there’s something I’m miss understanding, or it might be the cheapest esc I’m using, (these https://www.amazon.co.uk/dp/B074VY2S...ing=UTF8&psc=1)

ive put a resistor between the two contacts on each motor too.


one other thing driving my crazy, is that the right gimbal whilst moving forward, for some reason it effects channel three (which is connected to a servo for a lifter) meaning when I drive forward, the lifter begins to lift

Are you able to post a picture of the wiring of this at all? I wouldn't have expected this sort of behaviour to happen given the ESCs linked are single channel types. Is channel mixing enabled on the flysky?

Hi Sam
I use the same Transmitter/ receiver as yourself and in fact I have three because I find them faultless and easy to
operate.
On the other hand my ESC is a cytron 60 amp and cost 10 times the price of the one you show but on the plus side these
also have been no bother and can be used in heavies.

Some might say re bind the receiver but in my experience they tend to work or not work- though I know Theo had
major problems with his boring wedge and re binding did sometimes fix the problems.

I suspect it's the ESC and you might get a recommendation for what to use from the forum-maybe pay a little more
-those Lemon rx jobies I use in the beetle seem reliable.

I don’t have a picture, but I’ll try to get one. At times it works perfectly, also the red led on each of the ESC’s lights up when I move the gambal, like it should, or just doesn’t seem to always activate the motor, the red light responds perfectly

It could simply be a poor quality ESC as Colin mentions. I have this problem with a few of my Ants where it randomly moves of its own accord without any transmitter input. Sounds like chittering when it does. Lets try to rule out anything wiring or mixing related first.

A few years back I tried, but I found I had the same problems with the drive, I assumed it was the way I had cobbled it together, I wasn’t half as informed as I am now (and I still know next to nothing!) So I gave up last time. But I’m going to stick with it this time!

thanks for your help!

can you recommend any from Amazon prime?

sorry it’s a mess!

thank you for the help!

Also to mention, they’re 12v motors, being run from a 2s lipo, could that contribute to any problems?

I have had a look at the picture and I would take that servo out of the equation-it looks like a cheap
Chinese job and I have had tons of problems with them-use Futaba

Ill give it a try, Thank you!

The ESCs look like a rebrand or clone of XT-XINTE ESCs i use in my own beetles, which are less than $3 from their site: https://www.xt-xinte.com/10A-Brushed...k-p140167.html

I find these to be similar to the DasMikros often used in antweights, they either arrive broken or faulty, or they will survive any hell you can put them through, faulty or built like a tank and survive torture is the two options they leave the factorry in i think. You may have one of the faultier ones though.
The wiring seems good, so i don't think its just a wiring fault.

RE: the 12V on 2s lipo, as long as the voltage you're getting is enough to drive the circuitry of stuff inbetween battery and motor (the receiver, esc etc), it shouldn't affect anything, just the motors won't be going at full whack. It shouldn't cause the receiver to mess up and misinterpret signals, or at least not in my experience

Given the cheapness of XT-Xintes and alternatives / clones (honestly the amount of places and names i've seen on these identical circuit boards is in the dozens by now), if you don't want to go to a more expensive ESC, you could buy 2-3 and see if any work good, this is what I did, i have a backlog of them now, waiting for events to start up so i can get use out of them!
Unfortunately a lot of this hobby is trial and error, you may need to swap things out for alternatives and see what works and with what other things.

My featherweight uses a Cytron Smartdrive 30A, which is one down from what Colin & Myself have previously used in a HW. I have suggested to them a few times they look at doing a smaller ESC that'd be good for BWs & AWs, given their stuff is generally solid but also cheaper than similar. Alas, nothing yet! I've considered trying to run my own ESCs, I might have to go back to that idea!

Cytron do a 10A dual and single channel ESC (https://www.robotshop.com/uk/cytron-...or-driver.html for example) which may work in a BW application. It looks to be relatively trivial to wire it up, might pick up one for Shu! 3.0 to at least try.
