Thanks guys i appreciate it.

RE: E-FLITE BLADE CP PRO
 

No need, like i said that is normal for a servo plugged into the gyro, at least as I interpret your description.
It would make immediate sense to you if it was on a CP tail. On the BCPP, I don't think you can expect to be able to switch modes in flight, because of this sub-trim issue. If you set the rudder subtrim to get rid of the "creep" it's called, then the nose will drift in flight. With a CP tail, the thing can be set up to minimize the creep and allow switching modes in flight. I do not think we will be able to achieve this level of performance with the motor-driven tail system.
So just leave it in HH mode, don't worry about what a servo would do, zero your rudder sub-trim and flight trim, and set the GER travel limit at about + 50 percent to start with.

Oh, and be sure you have the _proportional mix_ pot on the 3-in-1 turned all the way counterclockwise to disable that function when you are using an external gyro.

It is somewhat normal for the 3-in-1 to get a bit warm even when the motors aren't plugged in.

RE: E-FLITE BLADE CP PRO
 

In HH mode the tail goes EXTREAMLY FAST or not at all. When it is going fast I try to slow it down but then it stops... Also some times the main motor surges.

RE: E-FLITE BLADE CP PRO
 

I already made a short video (30 seconds) and I'll post the link to youtube so you can see exactly what I am saying...
I have to make one with the ESC too so you will know.

RE: E-FLITE BLADE CP PRO
 

The first time it is in "standard rate"
Then when it stays it is in HH
At the end you can see the drifting

RE: E-FLITE BLADE CP PRO
 

And you know that both the rudder "servo" in the TX and the Gyro's own reversing switch have to agree, 4 possible combinations, only one will be correct:
Rudder one way, gyro one way
Rudder one way, gyro the other way
Rudder the other way, gyro one way
Rudder the other way, gyro the other way

only one of these 4 will be correct.

If you have exhausted all these possibilities, then I would suspect that the JR ring gyro is not compatible with the tail motor/esc system for some reason.
Time to call customer support at JR, I give up.

RE: E-FLITE BLADE CP PRO
 

I did not know that I'll try it now.

RE: E-FLITE BLADE CP PRO
 

Like I said, this is absolutely normal for a servo plugged into the gyro. I would show you the exact same thing with the rudder servo on my MX400Pro/Trex, but I can't make a video easily, and besides it would look just like yours. I assure you this is completely normal behavior.
The problem seems to be that your gyro/esc combo isn't behaving normally. If you have your reversing set properly I can't imagine what the trouble might be.
Can you plug a servo into the GER channel of the radio, instead of the gyro gain lead, and make a video to show what it does when you flip the GER switch (the right front one i think you said).

RE: E-FLITE BLADE CP PRO
 

This may solve my problem...
If you hold the stick just slightly left sould the servo coutinue going left slowly untill you stop or is it proportinal???

RE: E-FLITE BLADE CP PRO
 

Here is why the servo behaves as it does: In sr mode, you are telling the heli to yaw at a standard rate when you push the stick over. THe servo moves to do this. When you center the stick, the gyro thinks you no longer want a yaw, so it centers the servo (it is sitting there, you want no yaw, it detects no yaw, so it is happy.).
In HH mode, the gyro tries to move the heli to the desired heading. If you move the rudder over, the gyro thinks you want a new heading and moves the servo to try to get there. Since you are holding the servo in your hand and the heli isn't yawing, the gyro tries harder and harder to give you the yaw it thinks you want. After a while it gets confused, and won't return to zero when you move the stick back to center, because it still is trying to give a yaw/heading correction, so it creeps one way or the other, more or less fast.
With a CP tail one sets sub-trim to minimize this creep, you can try this too, but it will cause problems in flight with the motor tail. If the gain is set correctly, in flight there should not be a problem with trim in HH mode.

RE: E-FLITE BLADE CP PRO
 

THe gyro will drive the servo to give whatever response from the heli it thinks you want. So, no, not generally proportional, especially if you are not letting the heli yaw (like by holding it down, or whatever).
If you turn the gyro gain all the way down it should just pass thru the rudder stick input, so then it should be proportional.

RE: E-FLITE BLADE CP PRO
 

It is uploading now... The servo just goes back and forth.

[link=http://www.youtube.com/watch?v=JFKYgN_-d-Y]Here you go[/link]

RE: E-FLITE BLADE CP PRO
 

So that is completely correct also. Now the gain is just the travel limit of that servo. With it set negative (the left limit) that's the SR gain, and the positive travel limit (right travel) is the HH mode gain.

So now the only thing left is the reversing.
And if that doesn't solve the problem it is time to call customer support.

RE: E-FLITE BLADE CP PRO
 

What you said makes scence. I will have to try it with a motor now. I am willing to bet good money that it will work with the spektrum because the tail and main motor are not mixed. With my heli before they were mixed I think because with no gyro and the proporinal all the way down it did the same thing.

RE: E-FLITE BLADE CP PRO
 

I just tried it again (no gyro) and it worked! I can't weight to try HH mode! THANK YOU SO MUCH:D

RE: E-FLITE BLADE CP PRO
 

Don't thank me yet--something still might go wrong!!

And you can disable the gyro with it still hooked up by setting the travel limit (gain) to zero in the GER channel.

RE: E-FLITE BLADE CP PRO
 

All of my gyro testing was done on the ground with no tail motion. This is probably why it did what you said.

RE: E-FLITE BLADE CP PRO
 

I have to wait like 12 more hours (or so it says in the DX6 manuel) for the battry to charge. It says wait 24 houres.[:o]
It is way too windy anyway. Last night winds were like 20-25MPH I think... I don't know but it was FAST.
Now it is 15MPH or so it says on Yahoo...
I will have to wait because my grage is full of crap (stupid remodeling)[:@]

Thanks :D

RE: E-FLITE BLADE CP PRO
 

One more question...
If my Heli is perfectly still and I advance the throttle (no main motor) should the tail spin in HH or should it wait for motion?
When I turned mine on and gave it throttle the tail started to spin at full throttle is was still spinning slowly so it is not mixed but when I cut the throttle the tail stops.

RE: E-FLITE BLADE CP PRO
 

Does anyone know the O.D. of the boom on a CPP? Don't think I've seen it anywhere & don't have a mic. Want to cut my own.

Thanks!

RE: E-FLITE BLADE CP PRO
 

I ordered the blade cp edition of pre-flight. Its supposed to use the blade radio with its own cord (included). I'll let you know how it works when it shows up.

RE: E-FLITE BLADE CP PRO
 

CPP tail boom is 5mm but I use 3/16 inch carbon rod in 1meter length from LHS. Works just fine.

RE: E-FLITE BLADE CP PRO
 

Bart,

Off to LHS. Thanks for the info.

RE: E-FLITE BLADE CP PRO
 

It's really hard to say, the gyro could be picking up vibration and interpreting it as a yaw, etc. No system is perfect, the degree of perfection is directly correlated with price, and we are not very far above the low end here.
So before you get too worried, let's see how it performs in the air.
Just be sure your reversing is correct before you go to lift off.

RE: E-FLITE BLADE CP PRO
 

When you say reversing you just mean the gyro give the correct input (not opposit) and it respauns to Tx commands right?
Also there are no vibrations because the motor is seprate and not mounted...
