Blade Nano CP / NCPx

Attached is a config for the blade NCPx / Blade Nano CP.

DR/Expo for ELE, AIL, RUD with corresponding switches on the TX.
Throttle hold with Gear switch.

FMODE0 gives you normal flight mode: pitch mostly positive and 5 points throttle from -100 to +100
FMODE1 gives you a 3 points V shaped throttle curve 100-80-100, pitch is -100 to +100 linear with 30% expo.
FMODE2 gives you a flat 100% throttle curve, pitch is -100 to +100 linear with 30% expo.

Can obviously be improved / tailored to your needs but it should get you started and flying the little bird in a mater of minutes.

Icon for NCPx can be found here : NCPx icon

Have Fun!

Settings for beginners
Hold -> RUDD D/R
AIL/ELE 20%/40%/70% -> MIX 0/1/2
Timer stop on "Hold"

Thank you for this model config. I'm having some trouble with the channel settings. I'm using a Devo6, and my throttle and aileron are swapped, ie throttle is on the right stick in mode 2. I've tried switching between the 4 different stick modes but none of them work properly.

Well that is strange, I have a Devo8 but this should not make nay difference, model file should work the same on all models, I beleive it's the whole point in Deviation.

Not sure if you are using my template or Andrey's but anyhow.
You should check the mixer page and make sure channels are correctly assigned, should look as follow:

1-THR	Src: THR
2-AIL	Src: AIL
3-ELE	Src: ELE
3-ELE	Src: ELE
4-RUD	Src: RUD
5-GEAR
Ch6	Src: THR

Hope this helps solve your problem

These are the unzipped files Andrey already posted. They work great with the TH on the RUDDER!

Cool, had my nano up in a minute as you said:-) However, I don't understand how to adjust the tail gyro gain? I have tail blow outs and wag on my new nano.

Thanks,
Tom

I don't believe there is such a thing as gyro gain adjustment on the Nano (and on the Mcpx for that matter).

Tail blowout and wag can have several causes:

1- you are too hard on the pitch ... take it easy, or
2- assuming your nano is new, it can come from the fact that the motors are new. It will tend to get better as you put fly time on the heli, or
3- if your Nano is not new it can come from the fact that your main motor is on it's way out (something around 25-40 flight is considered "acceptable" for motor failure by HH btw on the nano), or
4- wag and blowout can also be caused by vibrations. In that case root the source of the vibrations, eradicate and all will be well ---> check blade balancing, feathering shaft tightness, check feathering shaft is not bent, check that main shaft is true (straight), check the bearings ....

Don't think I'm to violent. Flew my friends nano last week and it bogged before the tail blew out.

2- assuming your nano is new, it can come from the fact that the motors are new. It will tend to get better as you put fly time on the heli, or

Maybe, it's completely new. Think I have 10min flight time on it now.

3- if your Nano is not new it can come from the fact that your main motor is on it's way out (something around 25-40 flight is considered "acceptable" for motor failure by HH btw on the nano), or

(Watch my answers inside the quote)I've checked most of that besides the bearings. There is indeed a tiny vibration, but I don't think I can hunt it down.

I you sure there's not gyro gain? Doesn't seem like the gyro is in HH..?

Try flying at least 10-20 packs and see if the problem is still there, I had the same issue with my first Nano, went away after a "break in" period. Ditching the vertical tail fin seems to help with tail hold as well.

On the gain adjustment, again I do not believe there is such a thing on the Nano, if you find there is and how to set it please report back here your findings.

Ill try to break it in and remove the fin. Found an official statement from Brian James from HH that it wasn't adjustable.

Thanks for the help!!

I'm new to deViation, may be you guys are more expedience and can help me out to solve this problem.

I have some problem with the Devo 10 (deViation 2.0) and Nano CP. I downloaded the config file in this thread. When I'm in NORMAL mode, my throttle is at 0 position (-100), the main rotor still turns (very strange...). However, when I turned on THROTTLE HOLD (RUDDER D/R), then the rotor will stop immediate. Is it the problem of deViation 2.0, or Devo 10, or just the config settings?

Please enlighten me... Thank you very much in advance.

I have updated this config file to work on Devo 10, please comment if I have done it correctly.

Thanks!!!

Hi,

I did not manage to bind the nCPX to my DEVO 8 correctly.
Because of the behaviour the heli has when I switch to idle up mode, I think the heli is maybe in non programmable mode.

But also in normal mode, servos are acting too much, going to the end of their displacement too early. It is a bit like needing less travel adj, but I used your .ini, so it seems strange...

What is the bind procedure ?

Thank you

Edit : I have tried many other methods and it still does not work. The blue light keeps flashing slowly, motor does not start whatever the position of the corresponding stick (NOT a problem of mode)...

Did you follow the binding procedure found in the Nano manual?

Power on radio
---> Make sure throttle is 0
---> Plug lipo on Nano
---> Blue light flash
---> Press bind on radio
---> Jam rudder to the right and hold
---> Solid blue on Nano
---> Release rudder
---> fly

If you still have issues you might consider using 6 or channels instead of 4, just leave channels 5, 6, and 7 alone when setting up the Nano.

Hope this helps

Thank you, it was that

I was not sure that we had to do the same binding procedure. Now it is ok.

I have build a different config for the Nano.
I compared it to the DX4e delivered with the RTF model and there are some additional functions.
First is the trainer/bind push button. It is used for binding but also for throttle hold. To get out of the throttle hold mode you have tu push the trainer button three times in a particular time (2 second I think).
Second is the acrobatic mode. It is switched with a 2-position-switch.
My config makes use of both functions. As you can see there are the normal channels throttle, aileron, elevator adn rudder on the channels 1-4. Channel 5 is the acro switch where the rx switches to a v-formed throttle curve. I use the gear switch for this. There is no change for channels 1-4 necessary.
Channel 6 is bind to the rudd d/r switch and is used for throttle hold. As mentioned above: if you hit it, you have to switch off and on and off and on and off and on in two seconds. This is annoying and so I replaced the rudd d/r switch with a three-position-switch with a push button function down and a stable switch up. Makes it quite easy...
There are some expo and d/r configured too (on mix switch, 0=soft, 2=hard).

I am sure it can be optimized, but give it a try if you want.

So you have to bind it as a Ready To Fly (RTF) first before this will work. Meaning during the bind, you move the rudder stick to the LEFT. Why not just bind it so it uses 6 channels like a normal FBL heli? To do that just bind and during the bind move the stick full RIGHT. Then you have a 6 channel heli and can program it as such. ??
Sorry if I'm not seeing an advantage to this particular method...

Hexperience,
for me there were two reasons:
1) I wanted to have a config which is as near as possible at the original so that if someone is used to the DX4e feels from the beginning familiar and loves to use deViation.
2) I do not know (do you?) if there are differences in the flight behavior between the rx-internal programmed acrobatic mode and the one achieved with a 6-channel-config. There might exist some optimizations. For example I have seen that if you switch to acro mode while hovering there is no vertical movement caused by the different throttle and pitch curves. With my other (standard flybar) 6-ch-helis it is hard work to find the point where the curves are identical in the two modes.

Suddenly I remembered a third one:
3) Blade uses channels twice. The range from +/-60% is used for an analogue value like pitch, + or -100% is used as a switch between different modes. This is the way to control a 6-channel-heli with only 4-channel-tx.

Binding in Dx4 mode will enable predefined and static curves programmed in the Heli receiver (for pitch and throttle). So if you bind that way it doesn't matter what you set your Deviation Tx to, the receiver has the upper hand.

Binding in computer mode gives you full control from the Tx on every flight parameter.

While one may want to use one or the other is a question of personal choice. But investing in a full featured computer radio loaded with an unleashed firmware to use the predefined curves can sound like a waste of potential.
