Hello guys.
has anyone worked with the CCPM heli card on an actual CCPM machine ? like i said before i dont got the manual near me and would like to know if there is any significant difference from the Stylus' CCPM function to Futaba's for example... does it also offer rates for each one of the 3 servos etc ?
thanks.

I really can't offer you a comparison, but You can do just about anything with the Stylus.

You really need the manual for both the stock Transmitter and the card.

Are you referring to Futaba's AFR function?

I don't mind helping on the esoteric points of this radio but, at some point in time, you might need to sit down with the manual and see what this radio actually can do. It would be a good experience, instead of posting on RR and then waiting for the response. Just a thought.

I've never played with a high end Futaba but from what I understand, the Stylus does not have an AFR function per se'. For exmple, if you want to increase your pitch range, you increase the pitch AFR on a Futaba and all three servos are affected but only when you move the pitch stick.

With the Stylus you increase pitch range by increasing all the CCPM end points of all three servos but when you do this you also get increased cyclic movement so you'll have to dial 'em back down with dual rates.

The con is the Futaba is a bit more flexible/easier in its set-up (For more $$$ of course).

The pro is that the Stylus does not have so much processing to do.

Along with its already fast response, alot of people that have gone back and forth say the Stylus feels more responsive to stick movement.

Optech, there is a similar (not identical) function to the AFR (called CP-EPA), i think thats what you meant, and you can indeed change the % of the movement for pitch, roll and elevator, BUT - what i want to know is how do you change directions of the CCPM movement ? in the Futaba you can just turn the % of the AFR to minus instead of plus and it would change the direction of that control, but in the Stylus you cant go to the negative value of that menu.

so, lets take an actual example. lets say i setup a CCPM system and all the controls are working the right way besides collective, which is reverse, how do i chage that ? if i reverse all 3 channles the colletive will move well but the cyclics will now be reversed.

Tmoore, im afraid my heli crad came without a manual, so im trying to work on my own to see this. a guy here on RR sent me a scan of the manual, but there's no explination of the direction of the CCPM system.

I know what your talking about!!!!!!!!!!

I was a bit confused myself initially setting up my Fury for this radio. Its all in the servo reversing. There are 4 or 5 swashplates to choose from. If you want email me with the details of what you got for a heli the type of swashplate and so on. I'll look it up for ya.

Hawk4flyer, i will be installing a CCPm conversion on my X-spec soon, thats why im asking about it ! im not yet sure ill even need any of the reversing, but i want to know im covered.
so do you mean that if i just shoose the opposite swashplate type (i.e. 120 deg CCPM with the elevator arm in back instead of front of swash) that should do it ?
thanks.

Lior,

I sent you the scan of the card manual! The secrets to what you want to do are right in the manual. That is why there are three different types of 120 degree mixing. This does the same thing as AFR on the Futaba's and Swash mix on the JR's.

I've used the Stylus with the Heli Card (CCPM Function) on a Fury 61, Raven 50, Kalt Mercury 60, Predator.

No problems were encountered at all, the most important thing to remeber during set-up is to use servo wheels to the exact measurment that the manufacturer recommends.

If they say use a 20mm wheel, use a 20mm wheel, not 18.5 or 21. This is most important to get the travel that you need.

The stylus programming is very straight forward and all features needed are in the heli card.

I suppose thats one solution but I've never run into a situation that I had to select a different swash mode than what was actually used. Simply reversing servos does the trick. The one time it didn't work I tracked it down to not having the correct servos plugged into the proper channels.

In anycase, none of this is anything I would call similar to Futabas AFR function.

Mike

BTW..... What frequencies do you fly over there? I've got a 40mhz module, channel 79, and PCM receiver (no crystal) that I can't use.

Optech, im afraid that if you hook up the 3 CCPm servos to the Rx and in the example i gave, all move well besides the collective which is reversed, none of the servo reversing functions would cure this, if you reverse one you have to reverse them all as the 3 move in harmony, and then you would get good collective, but reverse cyclic. and if you just reverse the cyclic servos, the 3 wont move together with collective changes.

i sent you a PM about the module.

I understand what your saying. Like I said I've never run into a problem but thats not to say there isn't a situation out there that requires something creative.

Thats exactly what im after, the creative solution.
as far as i can think of, im not sure the different swash mode would do the trick...

Hey Terry.
here it is :

i have 3 hipothetical situations that i want to clear, in all of them the CCPM works perfectly besides the fact that 1 movement is reversed:

1. everything working well with the collective being reversed in direction.

2. everything working well with the Fore \ Aft cyclic being reversed in direction.

3. everything working well with the Right \ Left cyclic being reversed in direction.

please advise how one could deal with each of these 3 conditions.
thanks a lot for your help.

And one more question guys, what kind of servo wheels are you using the the Airtronics servos in a CCPM system ? are there "round" wheels that fit these servos ? or do you just use the stock ones ?

Please let me know what your radio is set to:

CCPM config: CP3 F, R, L or B

Ch. 2 N R
Ch. 3 N R
Ch. 6 N R

Based on your drawing, going CCW around the swashplate Channel 2 is on the top right ball, channel 3 is on the front of the swashplate and channel 6 should be on the remaining ball. Is this what you have?
