Newbies Help Setup (and understand mix)

[Danielowenuk]

Hi, first post so be nice

Previously flown a fairly tame 4 ch fixed pitch, just purchased a DX6i and a Nano CPS, which I appreciate may be a slight baptism of fire and will take some practice.

Just setting up the TX (waiting for the postman for the heli to arrive). I have set and have a "reasonable" understanding of what most of the settings mean.

I have come to set the mix setting and I have 3 options, swash mix, mix 1 or mix 2.

Swash mix appears to be disabled, so I have set the settings in mix 1.

The settings are
Gyro -> Gyro - ACT
D-80% U-0%
SW-Gyro Trim-INH

Whilst I think these are correct would love to understand what it actually does

Hi Daniel welcome to the forum.

Hey Daniel welcome, shouldn't the mixes be inhibited. What are you trying to do or is just for understanding what the gyro menu is and what it does.

Your swash mix will be inhibited because the heli you've bought is fbl and doesn't need the eccpm mix, your servo type should be set to single servo.

The other bits again should be disabled (inhibited)

[Danielowenuk]

Honestly, only going of what the manual states for binding DX6i at this point. As I said, I kinda understand what throttle curves etc do. But don't want to blindly set something I don't really understand.

Servo Mix is inhibited, and can't be changed.

Manual states the mixing settings I have put.

+1 on above, swash mixing needs to be disabled for almost all flybarless controllers. The controllers do the mixing themselves.

The Nano CP-S user manual should list the full Tx settings required for a DX6i. Just copy those and you should be good to go.

Edit: Sorry, just re-read your post and see that you've already done this and just want to understand what it does. As below it's using the gyro channel to switch the panic mode on/off. But I must admit I too find the mixing a bit confusing on these Blade micros. Easiest way to understand what is happening is to go to the channel monitor display and watch how the channel values change when you change flight modes or flick switches. You should see the Gyro channel change value when switching flight modes or activating panic with the Gyro switch.

The Nano CPS uses mixing to switch between different flight modes, stability, agility and panic/recovery. You will need to set up your DX6i according to the manual to get them to work correctly.

The mix sets the gyro channel level according to the position of the flight mode or idle up switch and the bind button when not used for binding

[Danielowenuk]

Ahh, that makes sense, so it's not a setting that is always involked, but should you whack the "Gyro" switch it uses the gryo mix to apply stability.

Heli sat in the sorting office, so I will be back tomorrow to ask how to fix it post crash

[Danielowenuk]

Well, 6 batteries in and it's not dead yet, actually haven't properly crashed it (yet). Battery lasts about 4 minutes, but I am guessing that's pretty typical, will have to grab some more.

Settings seem absolutely fine, actually much more controllable that I thought it would be, not flown the 4 channel for a while so very very rusty, tail in hover I feel about in control and move it around the room to where I want without going a ridiculous rate of knots. Any other orientation and my thinking time is coming into play (used feel a bit more natural when I had been flying the 4 ch for a while), having to land quite frequently with a side on hove just to orientate myself, either that or turn it back to tail in.

Its definitely much quicker than the 4 channel even with the dumbed down settings of beginner mode.

Did quickly flick the crash switch... er I mean f mode, yeah that's getting left alone for a long time.

I have found every now and then it almost vibrates a touch, it's hard to describe, doesn't have a massive impact on control and majority of time it's rock steady, any clues on what this is? I thought at first it was battery dying but it did it about 30 seconds into 1 battery.

Big thanks to everyone who has advised so far.

Welcome to the forum.

You are doing well. The addiction has taken hold.

[KMB]

That vibration thing, often refered to as a twitch seems to be quite common on the CPS, nobody has yet found a reason for it and so long as it doesn't affect you too much don't worry over it.

4 mins is about right for flight time if you are only poodling about, best not to let it get to lvc as the batteries are going to suffer

[Danielowenuk]

Not doing too bad, managing to stay in control in most orientations, although still definitely more comfortable tail in.

Did have a quick play in "Stunt" mode, managed to get a reasonable hover going on, until it went a little bit daft and managed to have a blade vs floor incident (broke a rotor blade), fortunately have a spare set, but better get another set on order.

I am trying to figure out what an in-between level is, tried reducing the expo, but doesn't appear to make a massive difference, played around a little bit with throttle curve (set 0-90-90-90-90) but still didn't have a massive impact.

The option that appears to make a big difference is the Gyro setting, manual says to set;

Rate	SW-F.Mode
0	90%	Norm	0
1	15%	Stunt	1

Reducing the Rate 0 % definitely increase the "Sensitivity" but also does something I didn't expect with the throttle. At 80% the head speed is not 0 at L position despite the throttle curve showing that it should be at 0.

Any help understanding this?

[Peteski]

If you are trying to set an intermediate level, then reducing elevator/aileron D/R and/or increasing Expo in stunt mode would be the obvious thing to tame it down. I'm not sure how the gyro setting works on this heli, but I would imagine it's just a switch for the self-levelling mode rather than a tuning parameter. I would leave it at the factory setting.
