Well after several tests on this I'll admit I wasn't really trilled with the 140 set up with the mixing. Seemed like the helicopter just wasn't right. I went through the set up over and over with no improvement. I finally decide to go with the 120 and reset the helicopter up. Flew like a champ right out of the gate. There's something about that mixing that I just couldn't get right and figured why risk the heli over a little work to switch it over not to mention a prefect time for a little PM on it. Thanks for the help. Mike

Thanks guys for all the info.i just bought a used Vibe 50, and its setup for 140. The 120 parts come with it, so I might swap it over, as I too , use a DX-7.

Whats the dreaded HUM??

Don't be bashful about using the mix with a DX-7. I have one Vibe setup on a DX-7 using the elev./ pitch mix. My second Vibe is on a 9303 that is 140 ccpm capable. Once you increase the elev. percentage in the swash menu there is no difference between the two machines. The swash action is identical. The only down side for me with a DX-7 is using up one mix that I would like to have for diff. speeds with the flight mode switch.

I set-up the mix..I ended up with 20 on the mix and - 50 percent on the swash mix. if I went positive my futaba servo's ran backwards.

I had to lower the swash mix settings t o50..I had 15degrees pitch, I 'm just a hair over 12 now

The only thing is, my elev mix is the same50 percent, where everyone else has a larger number??

If you have a pitch gauge, you can check your cyclic throws. Move the collective stick till you have zero pitch on the blades. Line up the blades with the boom and give a left or right cyclic command and check the pitch on the blades. Then line up the flybar with the boom and give a elev. command. Increase elev. swash value till it matches ail. cyclic. Go fly

Hi

Yes, don't do it.
Anyone who says it works hasn't really looked at it properly.

A well setup 120 ccpm is good, why do a very bad compromise just to have 140?

Regards
Paul

Please explain where I should look. My swash travel is the same, my cyclic throw is the same, both machines fly the same. I just don't get these sweeping statements with no support

Hi

The problem is the elevator (for/aft)
The mix people are doing works only at one position. Most do it at mid stick.

Watch the centre ball of the swash. The swash should rotate about the ball, with no up/down movement while you go from full forward to full aft on the cyclic. Check at full, mid and min collective.

Regards
Paul

I can't see how this is true. If anything 140 should be slightly better. The back servos work twice as much as the front on elevator swings.

If I were to be really cynical I'd say that the software on the DX-7 for 140 CCPM is dire - which it probably is for a radio at that price point. We had a Vibe 50 pilot too who did not like 140 CCPM, after trouble shooting for some time it turned out that he was using a Futaba 10C (which is just basically an upgraded 9C), and as you know the software for CCPM on it is really dire. He has since bought a 12FG and problem went away. (The 8FG would have done the trick as well since it has the same mixing as the 12FG and the 14MZ).

Hi Paul
I have since upgraded radios so I can't check this setting. But I do remember that the elev. cyclic percentages had to be increased and also that any significant amount of subtrim would show up as interaction like you are describing. Not trying to beat a dead horse but it worked for me for a whole season.
