e-Gaui Hurricane 200 & 550 - EP100 > pitch setting

hi,
I can not get the pitch settings right on my hurricane. My linkages are all correct and exactly the same lenghts. At zero pitch when the flybar is straight the pitch is way off and the same at full negative and full positive pitch. Any suggestions what else I have to look for?

have you got your stix on tx in the center.... throttle curve at 50% at centre and pitc curve at 50% at centre(of a 5 point pitch nthrottle curve)..in idle up1

I have checked all that and sometimes I get it right but then it goes out of pitch next time I check

Pitch...

Have you watched the Finnless videos on setting up the heli? If not...do it, they are a great help.

What radio are you using.

Go over the directions again and notice the way the three arms,are supposed to line up on the side of the fuse...

I followed the directions and everything came out perfect.

If you set it up and tightenend everything, then you don't get he same reading nezxt time you check you have really gotten something out of adjustment....

Give us some more info on what you are doing...

Hi,

all my servos move in the right direction and yes, I have watched the videos and everything is setup right. My radio is the futaba 6ex and everything is set at neutral. my swash is set at 3-S and everything is set at 50% (pitch, elevator, aileron). The pitch is not of by alot maybe 1-2 millimeter but yes it is off. I have no trims or subtrims, the servos straightened perfect but the pitch wont.

Have you flown it yet?
If not check and adjust the pitch on both blades.
If you have ,one blade will be off a bit.

When you say the "pitch is off" what exactly do you mean? The swashplate is not level when all the trims are at zero?

If each of the 3 servos are at their center point they should all travel up and down together, provided no aileron or elevator input is given. Do they travel together, and at midstick are they all lined up, and are the control arms as shown in the directions at right angles?

You may even have to use "trim" to get the servo arms perfectly aligned before attaching the linkages. The linkage from the "control arms tp the swash are non adjustable as is the washout arms to the flybar linkage. also ensure your linkages are are on the "leading edge of the blade holders"

Are all the servo wheel holes drilled correctly? Both push pull rods should be the exact same length...

Pg 18 of your manual shows the use of trim afer you have trimmed using the front trim levers...page 7 also shows how to use the offset on the control arms to correct for small deviations...maybe that will help.


Sorry if I seem to be covering basic items , it's just hard when not being able to see the heli.

Can you post a video or pictures showing the problem?

What confuses me is when you say you don't the same reading each time....even if its wrong, if everything is tight, you usually get the same reading even if its not what you want.

ok let me clarify this. My servos are centered, I use the JR large wheels to compensate for the offset and my linkages are exactly the same lenghts all over the heli, from the servos to the swash and from the swash to the head. trust me I have rechecked a gizzillion times. my swash is centered at midstick and when I give pitch all servos move in the right direction. e.g all move the swash up when I give max pitch and they all move the swash down when I give min pitch. I just cant get the pitch -10 +10 and the problem is as I stated earlier that the pitch reading is different evertime I read it. Could this be cause due to slop in the head? I have not flown the heli yet so that would be very weird but maybe that could be the problem.
I'm confused regarding trims. Some say I should not use it before flight, that is all trims should be set at zero and I should get the servos 90 degrees without trims. Now you say I should use trims to get the servos 90 degrees, what is the right answer. When I hook up my servos mechanically I can see that they are off by maybe 1 mm, does that affect the head by that much? I'm confused

when I set the pitch is off, I mean that at midstick it reads zero for both blades, but at high it reads 9 degrees on one blade and 10 on the other. at low the same thing 9 degrees on one ad 8 on the other. Referring the Bobs videos if I get zero at mid and different values at low and high something is wrong with the setup but I cant find what that could be.

when you are checking pitch... it is important to have the blades 90° to the boom... or inline with the boom. If you check them in any other position... you will not get good consistant readings with your pitch guage.

also... you need to make sure the flybar is level... and in exactly the same level/ position as the last time you checked it, before making your adjustments. the Hurri CCPM mixing in the head... makes it hard to get consistant readings with-out a flybar lock being used on it. I learned this the hard way... as I was getting inconsistant readings... even though I had the blades 90° to the boom... it ended up being the flybar not being in the exact same plane (level) as I used when checking it the time before... even though in eyeballing it I was close.

Get it as close as you can... check it a few times... fly it and set the tracking on the blades... and you are pretty much set to go. Even with-out using a flybar lock... you should be fine to fly it.

You only need the blades in line or perpendicular to the boom to check cyclic pitch range. The collective pitch should be the same anywhere in the rotor disk.

I agree with the two above posts...you might not have any problem at all.

I made a flybar lock similar to one provided with my ECO 8 ....its just a lenth of wood that slips on the fly bar and on the canopy mount....it holds the flybar level and I usually get the same readings.

As mentioned, get it close....fly it, track it, and see how it goes...
