at witts end with this set up need help 550

[dominic]

i have spent 2 full days trying to build this damm chopper,i set all electronics up fine and servos, watched finnels viedo on servo set up 10 times at least, it looks simple,he says get these arms level and hook up links, sounds easy,i un hook everything , and try to get all 3 arms leve the straight one for elvator, and the two on oppiset sides,there is no way to do this my swash will not be near level like this , i look at other peoples they are like his,mine are so out of wach to get the swash level, i put a picture in and it cont, right up the head ,i am ready to sell this ,i cant do this , i put a picture so you can see how wacked out this looks,

It looks like one of the holes you drilled on the front servo wheel is closer to the centre than the other.

as for the elevator setup, either you didnt install the servo wheel with the servo centered, or you have moved the wheel after turning off the TX because its not even close.

I just built mine a few weeks ago, and it set up almost perfect, and I used the finless video.

[dominic]

i cant even get it with out and severos hooked up? i undo the links,and place the arms where he says ,and in no way can it be done i get the 2 on the right side like he says ,it is fine ,i move to the left put that arm level and the swash is so out of wack it is not even funny , i am pretty good at these things i set all the elec. up fine and gyro and tail servo, but this is driving me nuts and then look at the blade grips how out of wack they are , gaui also has unadjustabel links that is hard to work with, i am ready to sell it , it looks like links are not right because that is the way i had to do it ,i leveled the swash and then hooked up the links,

if you have the arms level on one side.. then setting it level on the other is easy. now, before you throw in the towel.. ready heli sells a nice swash leveling tool that will make sure you get the swash set to 0 degrees.

looking at the pic you posted.. I can see the elevator is not at 90 degrees and the pitch/roll arm is not at 90 either.

[ICCA]

This is how it should look, at, or near mid-stick. At this position, I am about -2 deg pitch.

Dominic,

All I can say is PATIENCE. It took me a couple months to figure out how to set up my heli correctly. I would recommend that you take your time to set up your Hurricane. You can search all the websites and read about setting up and flying remote control helicopters (trextuning.com is a good website so is this website). It is a lot of fun if you do it correctly. If you rush, you will be frustrated with all the repair works. Look for an experience pilot near where you live, ask him for advice, have him look at your Hurricane before attempting the first flight.

You have a very nice Hurricane there. I promise you will have a blast seeing it fly the very first time.

Good luck.

thanks guys i see how you have those levers in your picture ,i tryed that and there is no way mine can do that unless i take apart stuff but out of the box it is impossibal,dont know what to take apart to try , to fix it,i have a guy near me that might be able to help ,i just cant believe that it is so hard to do out of the box unless the guy that sold it to me did something first ,but he said he did not ,

Dominic,

I think that you would find it easier to start from scratch, and something that will make it much easier to set up is to get the CNC pitch aileron and elevator levers

With these you don't need to set-up the offset on the servo arms and I'm sure that we could have you set-up in an hour or two top, particularly if you get the swash leveller also

Unlikely as it sounds the fixed links actually make it easier to set up the Gaui head.

Cheers,
Mike.

thanks guys you are great to take the time to help ,i will order all this stuff tomorrow, and i was going to get the hurrican servo horns but I dont know if they fit hitec servos

[Sircrashalott]

thanks guys you are great to take the time to help ,i will order all this stuff tomorrow, and i was going to get the hurrican servo horns but I dont know if they fit hitec servos

just remember you want everything level at mid stick

use subtrim to fine tune if arm angles are off a little

[Mikej]

Dominic,

I have two 550's and use the following approach.

1. For each servo set the first link so that it is the length of the distance between the middle of the servo and the middle of the lever pivot (red arrow), and then adjust it's twin to the same length(green arrow). Repeat process for all 3 servos.

2. Set up a model in your Tx with a 120 degree swash. Set up a pitch curve of 0, 50, 50, 50, 100 (assuming 5 point pitch curve). Now switch your Rx on (with all 3 servos connected) move the throttle stick to half way and let the servos centre.

3. Attach the link balls as shown in the photo below and attach the links to the balls, get the angles of the levers as shown in the picture below
http://www.helifreak.com/attachment.php?attachmentid=42659&d=1206115305
now without moving the servo or the CNC lever push the servo arm onto the servo.

You may need to reverse the servo direction and maybe move the balls onto a different arm of the servo horn if it is not lining up perfectly - but this should get you started. Once you get to this stage we can help you with the next steps.

Cheers,
Mike.

Dominic.....

you also must first make sure the servos are operating in the correct direction......

I set mine up as follows....

1. left stick at mid position.....(no servo wheels attached)

2. attach servo wheels so levers are as close to parallel as posible..any not parallel can be corrected with subtrim....at this time I would check to ensure they ALL move in the correct direction...right aileron....right servo pulls right side of swash down, left servo pushes swash up....rear does nothing. adjust servo reversing to get this correct before going and further. (sides are like you are sitting in the pilot seat)

3. forward elevevator,,,,front two servos pull down, rear servo pushes swash up.

4, pitch....stich up...ALL servos push up....down all servos pull swash down.

Make sure all servos work correctly as above......if with the left stick in the middle position (zero) any lever is not parellel either reposition the wheel on the servo or use sub trim to get it correct.

It really is not that hard....

If you still can not get it correct...PM me your phone # and I'll try to walk you thru on the phone....maybe you just have the servos set up wrong.....

Your picture it also looks like the servo wheels are not drilled correctly.....recheck those....and use the template that is in the manual....

ok guys i am going to put all parts in line with out links attached and take pictures to show you what i am dealing with ,i tryed again ,i will level the swash and you will see what i am talking about stand buy for pictures and thanks for doing that digram it is what i have been trying to do all week end ,

[dominic]

ok here is the left and right side with the angel i want ,and the middle is at the point where i cant move it or it will move the fronts out of line ,this is what i am dealing with look at the swash ,

[dominic]

ok guys this is as level as it gets no more no less this is it ,look at the lines there is no way for me to get this like you guys have yours i have now stripped the middle screw on that up and down one under the swash trying to take it off to move it , but even with this my blade holders are out of wack,which i will deal with later

[Sircrashalott]

tt

[Sircrashalott]

show a pic with ele arm straight up and down also

edit....ok I posted to late

You are probably better off starting from scratch again taking it one step at a time using the vids.....

Just think once you get it you will know it inside out.........

[dominic]

here ya go elv. straight up and down

[Sircrashalott]

Wow.......something is definately amiss........

double check your ele arm assembly is put together correctly....looks like the culprit compared to mine

[dominic]

it is that is what i was thinging can i rotate it some how then i will be fine i took the arm off and the screw off the other side ,but how can i rotate it?

[Sircrashalott]

with the ele arm straight up and down what do the front arms look like when bringing swash level

[Sircrashalott]

dominic ..in this pic it looks pretty close, level the arms out from the center bolt and see if it helps

[dominic]

this with the other side level and the elvator level now look at the front one

[Sircrashalott]

if you level out that front one you are there.....

[Sircrashalott]

here is mine
