According to the article in R/C Heli page # 54 the new Vibe helicopter
due out sometime??? will have 140 - degree CCPM mixing and JR
is the only radio manufacter at this time to offer 140 - degree mixing!!! on the 10 SX or XP 9303 radios smart those guys at JR.
That is one way to boost radio sales or decrease helicopter sales?

What do you think about 140 - degree CCPM is it a blessing or a
sales gimmick?

Thanks for the info on the Futaba 14 MZ Heli radio.
I checked my Futaba 9Z WC2 and it only has 120 -
CCPM mixing. I'm not going to spend $ 2100 on
a new TX 14 MZ just to fly the new Vibe helicopter.

Most radios can be used with 140d swashplates You just need to know the right mix.

Hey BT, calm down dude. The Magazine was wrong. It isn't the first time either and won't be the last time. Check out another section in that same mag and you can buy a carbon frame set for a TRex for $12.00 too. Sign me up for that but I want the real carbon frames not the faux plastic one that is pictured.

Vitek's post revealed the answer for you. Doing 140 degree CCPM is no problem with any radio that has a free mixer and 120 degree CCPM.

MAN is right up there with the new West Coast heli mag in terms of putitng out good info.

If it is like the CS,you can use the shorter balls on the swashplate that will make it function as a 120 degree setup.

Futaba's FF9 Super also has 140 degree mixing as standard.

I don't see any reason why a 120° mix wouldn't run a 140° swash just the same. As far as I can fathom, 140° swash doesn't require a special 140° mix. If 120° mix ATV/EPAs reach the desired swash deflections, then it's a done deal. Nothing tricky about it. I could be wrong, but this is my impression.

No, that's not how it works. You're talking about a control system algorithm that is computing how far to move the servos in commands other than pure collective. Since only 140d eCCPM has the distances of the outer swash ring balls equidistant from the center of the swash, it takes a different program than 120d eCCPM (or a 120d program plus the mixer) to deal with the elevator commands appropriately. If the same 120d program worked for both, Futaba and JR wouldn't waste the memory having separate swash menus for each.

The 9Z can get 140 to work using 120 and some mixing, I recall seeing someone post the how to... don't recall where or when I saw it but I remember the topic was discussed thoroughly.

If I had a 140° heli I'd give it a shot just to feed my curiosity.

"If I had a 140° heli I'd give it a shot just to feed my curiosity."

All that will happen is with collective above mid stick there will be an automatic elevator input and collective below mid stick there will be an oposite elevator input. With only collective input, the swash rocks forward and backwards, but aileron stay stable.

Nocontrol,
I might have misunderstood you, but you've got it wrong.

There is no change when using just collective input only. The issue is when you use elevator.

The PMIX uses collective to compensate when an elevator control is made.
If you didn't use the PMIX, when you gave back elevator there would be a positive pitch interaction and vice versa.

SORRY!!!!

I did the mixing a long time ago and yes I had it the wrong way around. Elevator effects pitch and not pitch elevator.

140 CCPM just requires a single mix, no big deal - the Futaba FAQ, which is linked to above, tells you how.
