Flymentor servo and wiring help for beginners

[Ivor Hill]

Before we start please disconnect your motor and set your transmitter swash type to one servo. If you have this correct only one servo will move per stick movement.
Flymentor ( FM ) can be made to work wired different way's but we will wire it as per manual.
Connect aileron servo to port No 1 on FM module, pitch servo to port 2, elevator to port 3 and tail servo to port 5. Now connect FM to your receiver, plug with 3 wires to aileron socket,yellow to elevator,orange to pitch, rudder normally port 4, green gyro sensitivity normaly port 5 and blue FM sensitivity to aux normaly 7.
Load Helibal onto computer and power up FM, you should have a flicking green light.Now connect cable and FM should link with programme.
Click on read and programme will read FM settings.
Click on servo tab and operate collective pitch stick and change direction on any servos ( in the programme not transmitter ) so that all three servos are raising the swash ( lowering on mini titan ).and send to FM.
Now operate elevator and aileron, if either or both are moving the swash the wrong way click on control and reverse it or them and send to FM. Sticks should now be operating correcty. If you cannot get this to work go to control and reverse pitch ( this should read collective pitch ) click servo tab and start again.
Now lift the heli and tip it the swash should move in the opposite direction to correct, if it does job done. If the swash moves in the same direction click on servo tab and reverse aileron,elevator and pitch servos and send to FM. Now click on control and reverse aileron,elevator and pitch, send to flymentor and test again. It should now all work.
If this does not work for you, I'm afraid you will have to change some servo directions in your transmitter and it will be difficult to set up, I have not had to do this but some guy's have I don't understand why. Remember servo tab will reverse servos and control tab will reverse stick directions
For those of you useing futaba all servo's are set to normal in my transmitter with or without FM. Hope this helps some of you please let me know.
Happy flying Ivor Hill.

Ivor has it down quite well. This is the exact wiring and set up for my DX-7/AR7000, Flymentor, on a Heli-Max AXE 400. Basiclly, if the sticks were correct before Flymentor, I would not do servo reverse on the transmitter, as it would only add to the confusion on setup. Thank you Ivor, and Nightflyr, the helifreak theads, have helped immensely.

Hi Brad please post the servo reverse position on you dx7 it may be a great help to others. Thank you Ivor

DX-7, AR7000, Flymentor, Heli-Max Axe400
ch 1 Throttle Norm
ch 2 Aileron Norm
ch 3 Elevator Rev
ch 4 Rudder Rev
ch 5 Gear Norm Green Wire
ch 6 Pitch Rev
ch 7 Aux 2 Norm Blue Wire
I am running about 30% gyro gain, but have not fine tuned it yet.

The led red+green by fm controller is light, mean only balancing.
The direction of the movement of servo and the opposite direction of swash are correct.


The problem is that the gyro is not locked.

Are you using the the software to set your gyro gain or trying the gyro sense menu in your Tx?

nightflyr

yes I use the software to set gyro.

by Gyro-Tab:
- Gyro Sense 70
- other default

Advance-Tab:
- default value

Might be that your internal gyro can not handle the task..could try kicking the gain on it up through the software a few notches and see if that helps

HI,
If you are useing the software to set gyro gain disconect the green wire ( gyro gain ) from your receiver and try again.This wire should not be conected if you are useing the software to control gyro gain. You only connect this wire if you use your radio to control gyro gain. If you connect it gyro gain will be disabled in the software.
What model futaba radio are you useing ?.

I use futaba T7C 2.4 FASST (7channel). Ok thanks.

Tried using radio to control gyro gain was not successful. By gyro gain setting via software and gyro sense=15 (others default) I see no tail waging.
Test:
led on fm controller is light red+green .
During hovering flight (1/2 meter) the hely moves backwards. All the same wenn setting swash via servo-neutral-elevator.

I try...thanks.

Hi It,s the green cable for gyro gain. You have to decide what you want to control from your transmiter, gyro gain or flymentor gain. If you control from the transmiter the cable must be connected, if you control from the software the cable must be disconected.
So if you decide to control flymentor gain from software remove blue cable from your receiver.
If you decide to control gyro gain in the software remove the green wire from your receiver.
If the green or blue cables are connected it disables that function in the software,if it did not do this it is possible that both radio and software would be trying to control the gain. Hope this helps. Ivor

OK, now is green and blue not connected.

now can the Hely fly relatif calmly....but when helicopter lean to front, the swashplate lean to front too. what is to do...

HI try this, reverse elevator servo in transmitter, revervse elevator under control tab and send to flymentor. Please let me know if this works.It may be better to start in position mode, change balancergain to + 70. Ivor

elevator is by transmitter and flymentor (under control tab) in REV position and balancer gain is +70...save => but still not works.

Hi Looking at your helicopter from the rear ( nose at 12 o'clock)what servo are you calling aileron the right hand or left hand. Ivor

ok Jroth I can see by your schematic that you call the left hand servo pitch. I do not think you will make it work. Change aileron and pitch servos on the flymentor module so that port 1 is aileron, port 2 is pitch and 3 is elevator. Start set up again.
I am going to write some new instructions explaining this. Ivor

OK, I have just swaped port 1 and port 2 by FM controller. Now is throttle and elevator exchanged.
....
I have swaped the yellow and orange cable.

[Jroth]

I can now normal hover.

No do not swap the yellow and orange cables, orange must go to port 6 and yellow port 2. You must now adjust servo normal and reverse and control normal and reverse to make it work. But you can try my settings if you want. These are my settings.
In transmitter set servo reverse channels 1 2 and 6 to normal. In software set servo 1 normal servo 2 reverse and servo 3 normal, send to flymentor.control tab set aileron normal, elevator reverse and pitch normal and send to flymentor.Let me know if this works. Where are you from ?.
