Rockohaulic asked:
So what does a Futaba 9C do for swash mix?
The answer is different for the 9C and the 9C Super, so it depends on which you have. Either way, the link that jschenck gave you, above, answers your question.

Program mixing
So I set up my titan today with a 20% th mix and man what a pain in the ass it was... Makes me either want to just buy a governor, or get a 9c...I have a futaba 7ch, and in order to prevent "over driving" the servo I had to move the servo sub trim all the way up, then move the end points (both so its linear) then make sure all the geometry between the servo motor and link where right...which took for ever to get right...and it at this point is ok,,,I still get biding when I hit th cut, because th cut rate% only goes up to 30% and it need to go farther because of all the fandangling of the mid point end points etc... big head ache....but it will fly great, guess thats all that matters

The 9C Super actually has a predefined mix called "swash -> throttle" It gives throttle on any cyclic movement, and does so while still honoring the throttle end points. This reason alone makes the Super my choice over the standard 9C and 7C.

In a Raptor 30, I just loaded the following curve on my 7C for IdleUp 2

100 65 50 65 100

I took this off of Raptor Technique.

Actually RT says to use

100 60 50 60 100

I added the extra 5% in the middle just to get some more feel in the center and since I don't own a governor or a tach.

I am glad I read this. I am going to bring this down a bit.

In normal, I have 20 40 50 60 100

To get the head speed on my raptor at 1850 at zero degrees pitch I have 37% on the throttle curve at that point. My throttle linkage is set so that at a 0% throttle curve with the trim all the way down, the carb is fully closed, no binding. Prior to using a tach, I was running my throttle curve at 50% in hover with a tacked head speed of 2400. I like my head speed at around 1850 to 1950 in hover.

The rest of the set up seems like a bit of a mystery to me. I have changed my set up to hover at 3/4 stick, instead of 1/2 stick. This creates a steep pitch curve from points 4 to 7, as I only have -4 on the low pitch point. I hover with about 5 or 6 degrees pitch. When I was hovering at half stick everything seemed linear. hovering at 3/4 stick makes things different. Setting the throttle curve is.... well, I'm working on it. I spend a bit of time reading the web site at Raptor Technique and then seeing what happens. I found that the R50 with an OS hyper 50 in it, doesn't need to have the throttle curve set at 100% to get a great climb out. I have my throttle curve set to 88% at the top point with no problems.

One of the biggest benefits so far is the increase flight time. I'm thinking of getting a governor to help with this, but who knows.

All you guys saying that running midpoints of 55 or higher are nutz. Every heli is different, I.E. the linkage setup program mixing etc.. I just set up my new titan ad tried to fly it with a 100 75 50 75 50, dude the engine bogs like no tomarrow...Maybee my helis just tend to be different, I am now running 55 80 100...much betta...

hi
Hyper engines do not follow a "linear" throttle curve...

Found this the hard way.

try this , N-TH 0 30 65 80 100 / N-PI -4 -1 +2 +5 +9

I-TH 100 85 65 85 100 / I-PI -9 -5 0 +5 +9

this works ok for me i have the T6EXHP with 2 flght settings
and and fly a Raptor 50 SE, i am currently waiting on a DX7 Spectrum and Trottle Jocky Pro i ordered
ill have some more options when it arives

Yup I agree with the last couple posts I am running my titan @ 100 80 60 80 100 in IDL up. And it fly's great....if I drop the mid value any lower the engine RPM drops waaay too much to the point you can hear the engine dropping.

There must be a major difference in the transmitters out there. With servo travel at 100% both ways and linkage ball at 10.5 mm from center and the rod 90 degrees at both ends using a 7C 100,85,65,85,100 works great, keeps the head speed at around 2000 . Id have to say though it is still much better with a governor. It opens the door for many more moves! hehehe
