Default Beginner settings for MCPX & DX6i

Please do the zero pitch setup as shown first. Fallow link below!

https://www.helifreak.com/showthread.php?t=404898

This setup will give you quite a tame helicopter you can begin learning to fly in normal mode in doors or out.

As these settings calm the helicopter down considerably. The helicopter will not react anywhere near as violently to input, but will still respond reasonably crisp. I find adding a lot of expo I'm lagging way behind the helicopter. A small amount of expo on Aileron and Elevator 10 is nice, you don't want to be chasing the helicopter around with the stick, you want the helicopter to move when you tell it to move.

I have also addressed the issue of overly sensitive collective. The Pitch curve provided will make the helicopter not only flyable in the house but outside the helicopter will have plenty of power and will climb to 100' and fly like a homesick angel.

Also 0 negative pitch setting so you can learn to fly without drilling the helicopter into the ground every time you get into trouble.

Get in the habit of using the throttle hold switch to kill the motor when the helicopter gets away on you rather than chopping the throttle!

RUDD arrow left 125 arrow right 125
PITCH arrow up 75 arrow down 75

Throttle Curve
L = 0
2=40
3=60
4=80
H=100

Pitch Curve

L=50%
2=65
3=70%
4=75%
H=80%


If your MCPX is not hovering at shoulder hight 1 mark above mid stick. Please try using the pitch curve shown below. I have 2 - MCPX's and fly them both with the above settings but one needs a little more bite than the other to hover just above mid stick mark on TX.

Pitch Curve more bite
L=50
2=75
3=80
4=85
H=90

I have found that the 30% settings in the travel adjust menu are great for beginners just starting out!
But as soon as you can hover the helicopter and move it around a bit increasing the aileron and elevator settings in the travel adjust menu to 40% makes the helicopter handle much better and provides control authority needed when flying out doors and doing turns!

Please fallow link: https://www.helifreak.com/showthread...65#post3856265


How do pitch curves work for new CP pilots.

In the pitch curve section of your TX.

0 is full negative pitch. Lowest throttle stick position

25% is 1/2 negative pitch 1 quarter throttle stick position

50% is no pitch at all the blades are flat. This is mid stick position of throttle stick

75% is 1/2 positive pitch three quarter throttle stick position.

100% is full positive pitch. Highest throttle stick position

A pitch curve like 50, 50, 50, 75, 100 has no negative pitch below mid stick the blades will be flat.

The Pitch curve I suggest above for MCPX & DX6i, 50 65 70 75 80 makes the collective much less sensitive and no negative pitch so you will get a chance to learn how to fly a much tamer helicopter collective.

How the above settings work to calm your MCPX

I understand that your MCPX has liner travel servos. In the description I am using standard servos
as it is easier to explain whats going on and works the same.

If you take a standard servo. In this case lets say an aileron servo.

When the aileron stick is in the centre position on your radio.
Travel adjust is set 100% and so is DR 0 Expo, When you move the stick all the way right
the servo will move approximately turn in the direction programed.

Now take that same servo and set the travel adjust 30%
When you move the stick all the way to the right the servo only turns 30% of the
original turn at full aileron stick deflection.

The combined effect of this action reduces the speed in witch the control surface moves in relation to the transmitter stick as well as substantially reducing the amount the surface moves in relation to the stick movement.

Hope this makes sense

Thanks Ron,i gave these guidelines a try and all i can say is WOW.I did the zero pitch settings with the toothpicks then went step by step with your settings and for the first time i'm having fun with the mcpx,it's a whole new ballgame for me. Tom

Question

I think I finally have everything set like this thread calls for and I even set pitch to

Pitch Curve more bite
L=50
2=75
3=80
4=85
H=90

However, the heli will not lift off at all. Now what?

Default Hello

I just sent you a PM,
Lets see if I can help you get your helicopter flying !
I'm sure we can figure out what's keeping it grounded.

is there any other settings that i could use to tame my mcpx down more than your settings i have programmed into my dx6i? with your settings seems like i have to trim it alot to level out. this thing is hard to keep stable in air without making alot of corrections then it just dives one way or the other. sorry major newbie. i went from a mcx2 to the mcpx.

MINI, trimming should not be done to the mcpx.

Default Hello

I do not know if you have read any of my other posts.

https://www.helifreak.com/showthread...81#post3854881

https://www.helifreak.com/showthread...65#post3856265

If you take a little time and read the documents you will have a much better idea what is going on.

If the helicopter is constantly moving around on you, this is normal for new collective pitch pilots. I can tame the helicopters controls down but I cannot make it fly like a coaxial.

When the helicopter is moving in any direction. gently bank it the other way so it slowly stops. Just as it stops level it out flat. When it moves again, bank it gently the other way and level it out just as it stops. again and again and again. This is how you control any helicopter that is not a coaxial. I understand that you are having a hard time, and wish I could do more for you. Just relax and give yourself some time, it will get easier.

You do not need to trim MCPX ! not ever. Remember this. If you bank MCPX it remembers what you told it to do and does it until you tell it to stop banking. All you have to do is tell it straight up and down and it will stop sliding all over the place on you !
I hope this makes sense to you.

Please feel free to PM me if you need more help.
Ron

Thanks guys for all your help. After flying an mcx2 then this it a totally different animal. It gets furstrating at times. I just need more practice I guess. What are your thoughts on the flat blades vs the bullet blades. Does one fly better than the other?

Have set up heli for zero pitch without any problems, thanks to your great data sheet..

Have also put in your begginers settings into my DX6i, Every thing was looking great on initial ground runs , but got a fright when I did a check, to make sure that the the throttle cut was working OK.

I have been using Throttle hold as the cut off switch as you suggest on page 1. However on the settings you suggest I seeem get 100% power when the switch is used. Setting hold to H=0 rather than 100% seems to solve the problem.

Have I got it wrong and could another switch be used for throttle hold. As a noob when would you want to hold the throttle at 100%?

You want H values to be all 0% for TH. I think the pitch curve that was being posted refers to the N mode and IU modes. for H mode it needs 0% on all.

Default Hello Ingk

I have been over the Beginner Settings for MCPX & DX6i about 10 times looking for my error and cannot see it.

In the beginning the document asks you to fallow the EZ zero pitch setup link.
In the zero pitch setup you are instructed to program the radio as pr page 6 of the MCPX manual. At that time you should have programed the HOLD switch in the throttle curve menu 0,0,0,0,0. Later in the document you are asked to check and make sure the hold switch is programed correctly before moving the throttle stick. It is assumed beyond this point that you have correctly programed the settings on page 6 of the MCPX manual.

As the setup on page 6 of the MCPX manual is a 3D setup.

Upon completion of the zero pitch setup. You where instructed to make changes to the DX6i programing in order to tame the helicopter down. I cannot see where I instructed you to set your HOLD switch to 100%. I'm sorry for any confusion on this matter and will correct the mistake if you or someone else would take a moment and point it out to me.

Hope you are enjoying your MCPX and the settings I worked so hard to test and post for new MCPX pilots just starting to fly this wonderful little helicopter.
Ron

Is there some confusion between the Idle Up (IU) and Throttle Hold (TH) switches I wonder ?

"100% power when the switch is used" sounds like IU to me....

Sorry for the lack of knowledge but what exactly does idle up do? I understand TH locks your head speed and full rpms but not sure what idle up does.

Other way around IU(idle up) locks headspeed according to throttle curve mapping... TH(throttle hold) kills power to the motor

Hi Imzzaude

I screwed up !! missed the vital line re setup as on page 6 of manual !. Instead used the settings at the start of this thread. Will never make a proof reader.

It's a gread thread thank you.
