Calibrating Trim

[alex305v]

I was able to get my motors to work with the new controller but now my problem is that one motor starts way before the other with a lot more power...

I have the FS GT3B controller with two motors, two esc and two batteries. One of the motors start and the other one stay off, I push a bit more now the second motor starts working with a lot less power...

Anything in mind?

What controls are you using. More information would help the guys, help you.

He is calling the Transmitter a controller. What ESC are you using? Are they programed exactly the same?

From personal experience with the flysky fs-gt3b, I can tell you that your s.o.l as far as trim & eponential settings go, because they have a faulty firmware issue that won't let them work correctly. You need to run both esc's off channel 2 with a Y servo splitter. Depending on the esc's your using, you may be able to program them, so they react exactly the same. .

for ESC I am using Seaking 180A

A simple question have you switched the ESC's , then motors and still have the same issue?...what is your wiring setup?

Here is the PDF manual for your esc's

Plug the esc's in 1 at a time & go thru the throttgle range resetting process on each ESC. Then you should be able to run them both off channel 2 with a Y servo splitter.
Here's the basic process

Turn on the radio, pull full throttle & hold
While holding throttle, plug in ESC
ESC beeps once, then twice to confirm full throttle is set
Let off the throttle (back t neutral), ESC beeps once to confirm neutral throttle is set, then beeps 4 times for 4 cells confirmed & systems armed.

I did as you said, the problem is I turn on the transmitter, go full power, connect the batter, I hear a beep and nothing else (no more beeps) I did this before with an old transmitter and it worked just like on the manual... I will try taking a video and posting so we can all see what's going on.

since the gt3b has a faulty firmware Issue, reset all your trims & expos back to neutral to make sure its not receiving a screwie signal too...

[alex305v]

I cant set the trim to neutral because then the motors start at a high rpm ( in forward the second on reverse) trim is set at *B08. Expos is at 0.

Like I mentioned in post #7, this is a common problem. Set trims & expos back to neutral, then reset the throttle range on each t180 separately. Then plug both esc's into a Y servo splitter and plug them into channel 2. Remember your recievet channels, 1 to turn & 2 to burn, channel 3 is auxiliary.

both ESC's need to be programmed exactly the same and they need to have the same signal so they perform and run exactly the same. This is why you run them off the same channel after programming them exactly the same.

Make sure your throttle channel is set to reverse

I put the trim on 0 and set full power, connect the battery to the one ESC, and it sounds like it wants to take off (don't start but there is a noise to it) but no beeps besides the first one.

[alex305v]

Did as you said (Luck as a Constant) I went on and put it in rev but now is everything the same but in opposite. I was now able to reset throttle range but now the other motor has more power. Do you really, honestly think is the transmitter? if it is I will go on and get me a new one, the only one thing holding me back after spending over 1k is that so if I need to get something else I don't mind at all.
