please explain better, end points are at 100 in rudder channel.using aux 2 channel for gryo gain. not grasping how to set back in programming.

he is not getting full throw because his linkage rod is not adjusted right.
With servo ball set to 10mm I can't pitch slider to go to the ends. It will go to ends set to 14mm but tail drifts counter clockwise. any ideas
You must adjust it mechanically first.

Had that been the case I figured he would have said end not ends. My guess is that he set the gyro limits up (gyro programming - would be the limit pot on the 401 gyro) for the longer servo throw and now that he has switched to a closer in ball location the limit set in the gyro will no allow the servo to throw enough to get full travel to the ends.

In ALL of my experence with the newer gyro's travel end points in the TRANSMITTER has nothing to do with servo limits and only adjusts how fast the gyro will allow the helicopter to piro to the right or left.

I am having a similar problem with my 700 tail. I can't get full deflections with 10mm like the manual states. I have it mechanically centered. It won't reach either side...

If the wings are traveling faster than the fuselage, it's probably a helicopter

Kirk that is a good point.

How about you guys try bypassing the gyro, connect rudder servo directly to the receiver, and see if you have full throw? And make sure it's end to end, not just short on one side.

As for me, one the 700, even just moving the servo by hand it won't go to full throw. The arm just isn't long enough. It looks like I will just have to try a little longer and see how it flies.

What kind of servo do you have?

9256... I just read something on the "other" forum about it for the 700...

It turns out the manual must be wrong regarding the 700 because there is no way 10mm will give full throw. I will check and post soon on what distance will give 100% endpoints.

It was recommended to just plug in the servo directly to the RX and find the horn distance by what gives you full deflection on both sides with no binding. That will be the correct distance on the horn.

Looks like 14mm for the 700...

Finaly I got working fine!
I replace tail control arm I had some play there, also new ball and ball links, 10mm from the center, 48 on gain on 9303.
One think that I notice is that my batt is been drained more per flight and my engine is running a bit cooler.
The feel of take of is kinda weir!!!!
So I need to put more flight time to get used to it

btw for the guy who wrote that invert pirueting funnels are not possible w 3g BS!!!!!!!

Awesome, glad you got it working. Your experience kinda confirms the theory that 3G drives the servos harder, but makes the power system (engine/motor) work less.

I have say that Bert and Antony (I belive that's his name) at assurance give me some good points!

I belive that the sensors in the 3g are very sensitive and pick all the vibrations from the heli creating a bad tail gyro performance so from now on I will be stoking on ball links

Yep as I stated 14mm will get me there on my 700..... and all the rods are right, servo and back arm are 90 and slider centered. 10mm wont do it using a 9256. is Ren's working at 10mm on a 700?

WIth the tail servo rod at 10mm on the horn there is no way you can get full throw out of your tail. I went back to the outter hole on the horn (I believe 17.5mm) and the tail is holding fine..I may try 14mm if people are saying it improves the tail..Can anyone confirm that the tail performs better with the ball at 14mm..

Right, I was talking about 500 and 600 with regards to the 10mm measurement.
