PostPost subject: T23 transmitter settings
Reply with quote

Hi, i have an MJX T23 and have a question about the transmitter settings.
I understand how to move thru the menu settings and all the different switches on this controller. However it does something strange that i have yet to figure out. where my throttle lever is located, there is a switch just to the right of it. when i press it up or down, it shows "MSP" and then the corresponding %. i understand what its for and what it does. thats not the concern. my concern is that when i press it down or up SOMETIMES it will show "FTR3" even when im trying to adjust the MSP. what is FTR3? attached are 2 pics of what im talkin about.....

Hi ryn0909 and welcome to the forum from Wales.

Like Tom I've no direct experience of this transmitter.

From advert photos the display shows MPS 60, whereas yours shows 40.
In your bottom photo shows 20, if those are percentages, then possibly the FTR 3 might be a time related number, Flight Time Remaining 3 minutes, does the -20 change at all?

Can you up-load a copy of the manual?

this happens to be the only button on the remote, that has two different functions. im thinking its a mishap with the programming of the remote. i know that the msp adjusts the verticle assent and the 40% value is the highest it will go. and it will allow me to adjust it both ways. when it shows FTR3, it doesnt do it all the time but every few button presses it will adjust both ways. but it doesnt do it all the time. as far as a manual goes, it says nothing in there about FTR3 what so ever.

There are so many different manufactures of those coaxial helis it's difficult to keep track of them all and their acrnyms. They are different to hobby grade transmitters.

On the transmitter each joy-stick has two small buttons close to them. One below and one inboard.

In your top photo, your finger in on the lefthand inboard button.
Is that the button you're referring to?
If so, these buttons are digital trim control inputs. So if pressed upwards the max percentage is 40%

So from what you report of MSP and vertical assent I think that the mps = motor speed percentage.
The trim provides micro control of the throttle control opening of the main drive motors.

When the display shows FTR3 do the motors spool up any differently to when the display shows MSP.

Yes the inboard button on the left stick is the one im referring to. The motors do not spool up differently if the display is showing FTR3.

out of curiosity, why does the trim value of the MSP max out at 40% and not 100%??

The trim give fine adjustment over the lower end of the full throttle range.

In effect moves the 0% point of the main throttle range up to a max of 40% of that full range.

Anyway does the heli fly OK?

I've not been able to download a manual so it is difficult to know just what can be adjusted.
Is there a menu of what settings can be changed?

Can you upload a copy of your manual or a scanned-copy of it?

Thanks for the pics.

#1 When the parameter setting knob is depressed, does anything in the display change?

#2 Do both trim buttons below each stick function?


Could you take a photo showing the swashplate and servos?

to answer your questions....
#1 no, but it does give me a long beep

#2 no, the one below the throttle stick (left side) does not function. it doesnt move either.

Thanks for the photos.

So from what you've reported, the trim buttons adjacent to the right-stick ‘cyclic-stick' provide fine adjustment fore/aft and left/right, by moving the central for the main cyclic gimbal pots.

The trim button adjacent to the left-stick ‘collective-stick' provides fine adjustment of the throttle.

Parameter setting knob:
When you depress the knob the transmitter gives a long beep, indicating you've entered the menu, so what parameters does it change when it is tuned left and right?

How do the controls provide entry to what's being called gyro regulation, which is probably fine main motor control by witch spinning is controlled.

This one Burgess,

http://www.banggood.com/6CH-G6-XTR-4_0-Phoenix-4_0-RC-Simulator-For-RC-Airplane-And-Helicopter-p-914795.html

I think that the customs will return it themselves when they realise that they are not going to get any satisfaction from me. Banggood were so insistent on sending it - I refused a resend 6 times as I was sure that it was in customs here - in the end they sent it and then told me it was despatched. That was around 60+ days after the the first was sent, Should have arrived within 47 or the policy is resend.

There's a lad in the village who would love this extra one if I get it. He's fascinated by the models and does have a computer.

Tom.

Here's hoping the fair-trade fairy sprinkles commonsense dust on Don Quixote and he releases that flight sim.


As I don't have a fight sim I might get one of those really great price.
