Just got myself the 9650, and I was wondering how you guys set yours up.

DS on/off?
delay?

Do you guys just used the round servo arm? It seems kinda cheesy that a 60 dollar servo doesn't come with any other arm.

Thanks
Josh

DS Should be turned on! My gain is at 36% and it is rock solid. Delay is set just off 0 but under 25 cuz it's pretty fast at 6V

fwiw..

Using the 9650, gain in digital mode is around 50 to 55% depending on the heli...No delay, the round horn is great for this app...use one of the holes closest to the pivot for the ball..This will allow maximum resolution on the servo as far as travel goes...Set neutral point with 1-2 degrees of right T/R..Should fly like Da Bomb..

is the key to this combi to run on 6v? i have been having problems with mine and cannot get rid of a wag on 4.8v, i have moved the ball in on the horn to 5mm, made sure the linkage is nice and free,ds is on, carbon tail blades,no delay, sense is at 20% and just dont know what else i can do...

Thanks for the info,

HF, I think your issue might be high freq vibration. On my newly built SE, I was surprised at how little vibration there is at spool up. My current setting right now is at 50% sens with around 25% delay, and DS on.

The other thing is to try putting some delay because the tail wagging is another symptom of too much gain / too little delay.

Ive proved to my satisfaction that many wag issues are related to emi, especially on the carbon frames...At the risk of sounding like a broken record, the DX 6 techology seems to cure all ills...

401 settings with 9650
Hi Heliflight , if you have your gyro gain down to 20% , then really in doing that you have turned the gyro off, you do NOT want to be below 50% other wise you have problems else where on your heli, I too use the above combo at 4.8V no problems , my settings are gain both sides 60%, delay set to zero , DS on , small round disk the servo comes with using one of the holes on the outside of the disk pattern . the other thing i have done is to fit a steel ball and ball eye instead of "Z" link (do not like these), there are spares ito do this in the standard kit , and make sure that there is no sine of binding what so ever, if all is OK you should have no problems with wagging and you will have a rock steady tail, hope this helps....

Heliman1, not sure what you are refering to "problems else where", but I have my gain set to 25% and have put about 10 packs through it and all is well. It flies like it's on rails and the tail holds solid and steady, even in moderate wind.

Ignorance is curable, stupidity is for life.

What most people don't realize with the 401 is that in gyro mode standard on a Futaba radio 50% is actually 0% in HH mode, now if you take the gain down under 50% it turns the HH off and puts it in rate mode. Kind of hard to understand. Now if you go into your radio and enter the Gyro mode you can toggle between gryo standad and GY ON, with GY ON you can scroll past 0 and enter the amount of gain you would like- 0 being 0 in HH mode with gy turned on. This is the mode that I am in therefore thats why I'm only running about 35%, so guys that are running above 50% they are in the GY standard mode. It took me forever to figure this out. I probly just confused the heck out of you guys but it is what it is.

Mine is in GY mode on my 9C Super. Also the gain on my two diff t-rex is 36% on avc "HH", and 36% on norm mode. Fine and solid no issues and zero delay, and DS is "ON". Cheers

Sounds about the same that I'm running, what a great combo!

The delay pot is to compensate for a slow servo which the 9650 is not, if you need delay your setup is wrong somewhere. A wagging tail is too much gain, either radio or mechanical. You just need enough gain on the radio side to hold the heli in fast sideways or backwards flight, any more and you are just going to wear out the servo prematurely.

Mechanical gain is when the ball/zbend is too far out on the servo horn.

What I think a lot people don't realize is that 50-100 ATV for Ch5 is = to AVCS 0-100 for the Futaba 9C. Likewise 0-50 is like 100-0 for Normal rate
