I need heeelllppppp. Pleeeaaaase

[gasgasbones]

Hi all,

Well, ive pranged my Blade again.

After changing the cyclics to 65s i set the heli up no problem and then flew out a battery hovering about, all fine and dandy.

This morning I took it to the back field and noticed that when i input a signal for the tail then there was a slight "bounce" back.... I figured it might be something to do with the numbers I had set in the Gyro screen as shown here.

I then took the numbers right down and gave it a try, I set the top one to 50.5 and the lower one to 49.5!!!!

on lift off it span around, not hourendously fast but fast enough for me to panic and slam it down with the enevitable damage

Can someone here please tell me once and for all what these 0 and 1 rate numbers do and how they relate the gyro !?

also were it says SW i have it set at Gyro as you can see but what are F;mode and INH !!!!!! and what do they do.

Please help, i wanna learn but its sucking my will to live at the moment

Cheers all,

One day it will click, hopefully soon !!!!!!

The 0 and 1 relate to the switch position on your Tx. In your case, you have the gyro gain set on the gyro switch on the front of your tx, it can be changed to be selected with the idle up switch (F;Mode) if you so choose, INH means the gyro gain settings are inhibited (no switch selected) but why you would inhibit that is anyones guess!!
The settings (generally) , above 50% is heading hold, below 50% is rate.

[gasgasbones]

thanks mate.

So are you saying that the less those numbers are then in effect the less heading hold i will get ? So what should i set them to? 100 %

[Stuart]

Which gyro do you have ?

As murph say's is in relation to the switch position = the % you've set when you flick the switch the arrow I suspect will move. Been a while since I had a spektrum set.

In HH on the deck with the motor switched to hold for example if you move the the rudder off center the rudder will move then as you stop it will stay where you left it. In rate mode the rudder will move back to center.

In HH mode the reason it doesn't move back to center is because the its waiting for the heli to move to the position you've asked it to move too.

If your gain (too high a %) is too high in HH mode the gyro will start to hunt effectively making the tail bounce back and forth in a hover for example.

[Stuart]

In Gyro's that are likes of Spartan they work off the premises that 0-50% is normal rate mode and 50% + is HH (AVCS) mode.

[Stuart]

So for example if you set to 75% = aprox 50% HH Gain.

[gasgasbones]

ah right, so when i had it set at 60 % and it wagged a bit i should have turned it down a tad to get rid of the wag?

because i turned it down too far it was in effect no longer in HH hence the spin ?

the gyro is the standard Eflight Blade one.

Edit, yes, when i flick the switch the arrow moves to the 1 position

[Stuart]

So you have can have one switch set to rate on oneside and the otherside set to HH or just two levels of either. Your on the right path.

[gasgasbones]

Ah ok so one rate doesnt effect the other ? If I had one rate punched in for HH and it worked fine, any adjustment to the other number would have no effect while stayed in HH mode?

The rate numbers just effect the individual position that is selected ?

[Tmac]

THe gyro should still hold even when not in HH mode as long as you have it set up mechanically. You need to adjust the length of the rod that goes from the tail servo to the tail linkage to make sure the it doesn't spin, it's best to do this out of wind if at all possible. Just spin the heli up slowly and see which sick input you have to give to stop it spinning and adjust the rod to mimic that, i.e if looking at the servo the servo arm goes towards the heli to stop it spinning the rod needs to be shorted and vice versa.

Ah ok so one rate doesnt effect the other ? If I had one rate punched in for HH and it worked fine, any adjustment to the other number would have no effect while stayed in HH mode?

That's correct. The Arrow = mode selected (Either 0 or 1 depending on switch position)

[gasgasbones]

Nice one, cheers Stuart. Getting there slowly

... why you would inhibit that is anyones guess!!

I have mine inhibited and use the travel adjust on the channel instead - it amounts to the same thing really is all you're doing is giving the gyro two settings - the first for switch up position and the other for switch down position.

As I understand it, the gain on the standard gyro is 0-50% is rate mode and the lower number the higher the gain(i.e so 20% is higher gain than 40%), and 51-100% is heading hold with the HIGHER number being the greater gain.

I'm sure Boggy will jump in and correct this if wrong - in fact, it's great trying to answer others questions becaise it allows you to check your own knowledge... Ron???

Come to think of it, I haven't seen him on the forum recently???
