Hmmm.........looks like I'll have to give this method a try tonight when setting up my second Evo.

try it - you'll see what i mean. no reference point needed at all

Are you saying you just switch the radio on with the flybar & blade grips pointing anywhere,wherever they happen to be ie you don't line them up exactly with the boom first.
That is what your first post reads like
That is the reference point i mean.

I already use the cyclic stick paddle interaction trick as a fine tune after lining the inner/outer swash balls up first,but still with the flybar (or blade grips) smack in line with the boom line.
Are you saying you don't need to do that,have no reference point?

Please correct me if I'm wrong.

"Phasing" refers to cyclic interaction, for example; you command some down and you get some left or right mixed in there too.

Purpose of the mixing is to make the heli's response more closely fit the inputs we command from the transmitter.

Hirobo offers us a chance to adjust the "Phasing" or cyclic interaction, by positioning the 'radius block'.

An expert 3D heli-flyer would have the ability to correct any unwanted heli movement, as it happened, and therefore would not need any cyclic interaction built-in to the mechanics.

For the rest of us; Hirobo's words that "precise phase adjustments depend on actual flight" Seem reasonable to me.

I'm thinking I will adjust the radius block so that my heli responds in a 'pure' fashion, such that a commanded down cyclic gives the heli a down movement only, with NO right or left thrown in.

Now, my EVO will loop in a circle and end up where it started, not one of those dreaded spirals.

Whad'dya think?? Ron

It's the adjustability of the radius block that can introduce the interaction if it happens to be set away from neutral,
which may or may not be good , it all depends how it flies.

"phasing" or "timing" is the aerodynamic thing in heli's where you can end up with a non pure input because the rotor head doesn't repond in a pure fashion at the correct times.It can happen too early or too late and varies with different paddle weights,blade selection,rotor rpm and a million other different rotorheady things,flybar input versus blade input etc.So Hirobo and other manufacturers build a mechanical timing/mix option into the heli that is adjustable, so that if necessary some deliberate cyclic interaction is introduced.This can be done from the radio too and has the advantage of allowing different amounts of aileron to elevator than elevator to aileron,if you want to use the radio it's better to set the heli to neutral timing.

Timing adjusting on the heli is a pain in the arse and just another thing to check on stripdown/rebuild
With radio mix ,once you set it it is easily repeatable with a value or set of values if nothing else on the heli setup changes
,if you feel the need to set any in the first place that is

I am not disagreeing with anybody, but I find it very easy to line up the tail boom and see if the ball ends line up. If they don't then adjust.
I did not find it very hard in the manual, atleast in the freya 90 manual.

SteepCurve is absolutely right.
they put it there for you to have the option to play with it, but my method works well for those looking for a neutral non mixed head, like myself and most pilots i believe.

Lior,

Good pointer on the easy adjusting of the radius block, this is how I've been setting up my heli's, quick and easy. I do this trick with evo + x-spec.

Thanks

I found this technique worked on my Predator also (CCPM)
quick, simple and very accurate

I3DM -- maybe you should make a point of bumping this thread to the top about once a month.

Man i must be thick.
I still cant get the jist of what were looking for here..

I read this thread when Lior first posted it,
but can some one say it in other words.. i appologise for this but i want to understand but i see how this is being achieved..
Ive got my Evo in front of me now,
Radio on and flybar sort of 30 degrees, ie not anywhere close to the 4 x 90 degree intersects.

I know my phasings close because im not suffering to much corkscrewing but if i move my ail' the paddles twist and the same if i move the elev'.

How im i going to see no ineraction with the flybar not on the intersects.
I know ive missed this and i know it works id just love to know how.

I just found this thread and this is very good info.

From what I can tell you just give it some aft cyclic and look to see if it causes right or left interation.

Vigor, just line up the swash balls (inner and outer) and play with the right \ left cyclic, if there is interaction, you will see some fore\aft cyclic being induced together with the right \ left movements.

Ahhhh,
simple as that, thats what ive always done.
I couldnt see a reference to lining up the swash balls and i thought id missed something.

Sorry for being dumb, all clear now, thanks

bump.

Saw this post before but wasn't interested then, now I had to search and find it... became very important now that I understand, easiest way to do

Thanks I3DM.
