Avant Aurora - EFX - FX > avant rotor head

Well, i guess many people already try the new avant head.
this head is 100x better then any head i ever flight.

after i install the head, right after first fly i need to adjust
the phasing angle. the roll is not perfect.. anyways..
so i was wondering am i the only person adjust the phasing angle.?

PS.No one have more Avant then i do.. i have 3 avant.
think about getting my 4th one...hahaha

Augusto, u are the man...

Hey Inspiron
I also buy the avant head bat i have soma misapprehension....
The supplied 80 mm threaded ends rods seems to be too short it look like i need to use linger one (90 mm rod)(the rod that contact the Swashplate to the bell Mixing Arm ),
Second the link (rod end) that contact the bell Mixing Arm to the flybar have to be 2524-014 not the 2524-001.

If i use the 2524-001 and the supplied 80 mm rods
When the Swashplate is level and the blade pitch is 0 degree my bell Mixing Arm is in not parallel to the Swashplate - it have sharp angle.

( First pic this how my bell Mixing Arm look When the Swashplate is level and the blade pitch is 0 degree)

Someone notice\bump into this problem??
thanks

Inspiron,

The adjustment of the phasing has to be done in very small amounts.
To check if when adjusting it you went too far do this test.

With the phasing at zero do several rolls. If it corkscrews try giving a tiny amount of forward elevator on the stick. If that doesn't correct it then try a tiny amount of back elevator on the stick. If that corrects it then you know you need to do a phasing adjustment. Do it towards one of the directions very very slightly and try rolling again. If still corkscrews and to correct it you need to apply the elevator in the same direction as before then you need more phasing correction in the same direction. If the correction direction needed on the stick reversed then you went too far in the phasing correction.

This is all assuming you have matched the ccpm servos as explained here. If the servos are not matched you will only be msaking a different issue.

Guy,

This was posted in another thread but here it goes again.

The angle between the mixing arm and the rod coming from the swashplate needs to be 90 degrees when the blades are at zero degrees of pitch.

Many people make the mistake of trying to make the mixing arm level and doing so you won't get equal collective pitch right side up and inverted. You'll end up with more pitch inverted and your rod will appear to be shorter than needed because you're trying to incorrectly reach a point that is out of the reach of the rod.

Here's a drawing of the correct setup:

From a 90 degree point the travel of the swashplate up and down will give similar end of travel angles on both pitch extreme positions.

intresting point, when i setup the fury head. i never setup my angle between the mixing arm and the rod coming from the swashplate to be 90 degrees when the blades are at zero degrees of pitch.

why is that?

so if i adjust the phasing angle it does not do anything good on roll.?

i felt this head is much more aggressive then hirobo with avant head mod...

why is that?

please some one explain to me.

Inspiron,

Yes the phasing adjustment eliminates the corkscrewing on rolls.
Follow the method I posted above and you'll be able to eliminate it.

The head is as aggressive as you want or it can be less aggressive if you set it up for less aggressive response. That's why we called it programmable.

this is what it is supposed to look like.

Should the inner swash balls line up with the outter front swash ball and the guide pin intially?

by the way, you have gadget to adjust the flybar cage (both of the arms) ?

the thing in the foreground that is out of focus is a level that I have taped to the flybar. I use it to ensure that the flybar is level using Augusto's flybar locking tool

. the heli has to sit perfectly flat(level) for it to work. I used the bubble eye level from MA to make sure the wash out arms were level and the flybar cage also.
