CGY 750: Setting correct compensation direction
Guys,

There have been a few questions about setting up and confirming the piro compensation direction in the CGY750. There is nothing wrong with the instruction's description, but let me put it in other words.

First, go into the swashset basic. The first submenu is the piro compensation stuff. Turn the rotational equalization ON. Leave the phase equalization OFF for now (see my other reply just posted above). Leave the default Rot.HIS value @ 16 pending flight testing.

Now, put the model somewhere where you can easily rotate it. Your living room floor or kitchen island are good choices. When you go into the Equ.Dir menu, the swash is going to tilt with mostly full up on full down ele command.

The model's swashplate will be tilted towards some point in the room you're in. Next, rotate the model on its yaw axis 90 degrees either CW or CCW. The swashplate should now still be tilted towards the same point in the room even though the model's nose has a new orientation. Effectively that ele command tilting the swash towards a given point in the room will translate to an ail command pointing to the same point in the room.

If the swash tilt maintains the same direction, you're done. If it goes the other way, reverse the Equa.Dir. Done this way, there is little chance for getting is backwards. Either the swash tilts towards the same point in the room as you rotate the model, or it doesn't.

Now don't forget to go back get your headspeed numbers in the governor menu correct for what you're actually turning AND make sure you have the rotor direction and sensor orientation set as well (CW, TOP, etc).

Good post Ben.

When you said "[Leave] the default Rot.HIS value @ 16 pending flight testing" is this default value for 600/700 size helis? From my experience the default values do not work for 450/500 size helis.

The starting value of 16 was to my knowledge arrived upon from testing in mostly 600/700 class models.

Have spent a good deal of time fine tuning, it's very clear to me that you should be well prepared to tune the Rot.HIS value to whatever is needed for your particular model.

Yeah, that'll do it..........

I'm sure your piros prior to reversing the direction were a little bit of an adventure.

You look at the direction the mixer goes for correction to keep the swash level. If the mix is correcting the wrong way, those two functions will fix the direction. There is one for ail and one for ele.

Better?
