wig wag tail

I think the clue is in the statement you made when you said "When I turn heading hold off the gyro holds". It sounds to me that your radio (Super 8U) has REVO "TURNED ON" when you are in heading hold. With a 401 gyro in normal mode you can have REVO turned on but When you are in heading hold REVO MUST BE TURNED OFF. Also with the hawk sports and the 401 get your handy dandy plastic screwdriver out (You know the one that came with the gyro) and turn the delay down to about 70 all wig wag will cease.

is the engine running smothe? (hehe this parts funny) In g2 when the heli wags its because the engine is running to rich and something happens (vibrations maybe?) to cause tail to wag.

Black, I have had the delay everywhere from 0 to 100 with no results.

Briliu, the engine runs great! (OS50) I have tuned the engine and tried different fuels to see how it would run. I haven't had any problems with it.

The Revo thing came up yesterday when I took it to a guy at Hobbytown who has been flying for 5 years, and servicing helis. We took the radio to 0 on Revo with no result.
I also found a guy there that said he would buy my heli and to let him know if I wanted to sell it. Everyday I get closer to selling it.

QuestJinn,
You never answered my questions. If you REALLY want to sell the thing then sell it save yourself the hassle. To me it sounds like you don't want the heli and this is pushing you over the edge. If we were talking about a Predator here I bet you would bend over backwards 100 times to solve the issue.

I for one would INHIBIT Revo mixing. Go thru your radio and verify that you don't have any other mixes activated. Make sure you are changing the gain properly on that 8U. You never responeded to my question about how you have the gyro plugged in. Is this a "Super" version with they "Gyro Sens" menu? Are you using that or the ATV method of controlling gain?

wag with 8U

You probably have your gain wire plugged into your "retract" channel of the 8U. Note that the 8U retract channel will only adjust from 30 to 100 on one side and -30 to -100 on the other.

If you have too much mechanical gain (servo arm is too long) then you may need a gain sellection in HH that is less then the 30% allowed. In that case you will have to go to a shorter servo arm.

You may find it well worth reading the article on "Gyros" in the hints and tips section of the www.leisuretech.ca web site. It will help you understand these gyros, how they work and how to set them up.

Has all vibration been removed from the heli.

Are you running the servo arm at or below 10 mm.

Is there any binding in the TR pushrod.

Is there any slop in the TR pushrod.

Is there any binding in the slider pitch ring for the TR.

Is there ANY mechanical reason the gyro cannot do its job.

Just for thought.

Lift, I am not ignoring you, I had to attend the funeral of a friend so my mind was not on the heli yesterday. I do want the heli, but I don't want the problems, I am ernestly trying to resolve them but I also want to fly as a release. But it's hard to have a release that frustrates you. Yes it is a Super, with the gyro menu. And honestly, frustration is frustration, so be it a Predator, or a Faclon, or a Fury, the result would be the same with me. I don't have an issue with the money if that is what you are reffering to. Because if it isn't doing what I want, it just isn't, and my reaction would be the same, reguardless of the cost. I have to look at the heli to verify the channel for the gyro. I will post that later tonight.

Oldfart, I will try the 30% thing, but when I put it at 55% the wag gets veeeerrrry big. But I will give it a try. The control arm is the 19.5mm wheel. I have tried the smaller ones, none seem to make any difference though.

Hawk4flyer, I have addressed thoes things, everythig seems to be fine. I had some vets once-over the entire heli and they corrected some slop issues to no avail.

Dude,

It's vibration. Lemme spell it out to you. Too Much Vibration.

Symptoms, normal mode works, HH-mode doesn't? Had the exact same problem with a CSM540.

If you're frustrated, just fly it around in normal mode! That's what I did for close to 3 months and 2 helis later, then I found the problem. Heck, the way the Hawk Sport flies, just fly it around without a gyro.

2 possibilities. you gyro sensor is shot. or servo is shot. or there's too much vibration.

Check to make sure you got the right double stick tape securely affixing the gyro until wherever you're mounting it. Make sure it stuck on good,and in a place that doesn't vibrate. Try strapping the gyro somewhere else. The ideal place is a custom mount right over the boom in the back. The front lower tray vibrates alot, so does the bottom area between the tank and the engine (they are all too close to the engine). The frames on the sport are all nice soft and wiggly plastic.

Well, just my opinion. My source of vibration came from the engine itself and a bent crank. When I changed out to a different engine, everything worked out, even in the places I mentioned that were bad, but I did upgrade to metal lower frames.

I just thought of another scenario that causes WAG. If your normal mode isn't setup properly, the HH mode will wag. But if your normal mode is holding fine, and your trims are all zero'd out on the Tx, and the Revo is off (recommended for 401 gyros), then that means your normal mode is setup properly.

Jimmy,,, Jinn has tried 2 diferent gyros and 2 different servos and the wag was still there, I'm leaning with Oldfart, so if he dosen't have the tail gears reversed it must be the Tx !!

Jinn, remove that big servo wheel and use the long arm, ball at the end !!

Is there any way you can post a pic of your installations. Optimal pics would be both sides, front, top, 45 degree rears. and any other quadrant you can think of. This would help us alot. We desperately want to help you solve your problems.

Thanks guys!

I really appreciate all of the help. I am sorry I am not as responsive as usual. Still dealing with the loss. It is also raining here, haven't had much chance to get out. And the wind has picked up, with the temp. dropping to 50deg.

Old Fart, I still have to look at the sense wire. I WILL do that tonight. In addition, I really want to thank everyone with all of the help. It really makes me want to try even harder. You are a great group of people. Everyone!

condolences

This is the second time I post this - I do not know why my first one did not appear.

QuestJinn

I am sure that I speak for all the others on this Century Forum when I wish you our sincere condolences for the loss of your friend. I am sure many of us have had similar experiences and can sympathize in kind.

Questjinn,
I believe you had a post on this in April and thought you fixed it.
I know your frustration. I just fixed a tail wag in HH on MY Falcon.

I have a Falcon 46 with OS46, 401, and had a nasty tail wag in HH problem that was driving me crazy too. (see me previous responses to your first posting on page 6 of this fourm).

1) Do your T/R blades have any slop in them? Grip them and see if they twist at all.
2) is your whole T/R system smooth as silk or does it hang up? If it hangs up in any way, work on fixing that.

After trying 3 different gyros, I fixed it by getting rid of the slop and stickinees in the T/R system by replacing some parts with better upgraded metal ones. I can give you part numbers if needed.

Also, I had a fuel foaming problem (due to detonation?) that I got rid of by richening the mixture tw0 clicks. ?

One possiblity is to NOT fly it in HH mode until you fix it. My wag went away in forward flight or rate mode.

I am convinced that when beginning in helis, it is the struggle to get it flying that counts... I am a beginner too. Keep trying and be patient and persitent. Use your sim in the meantime. Learn nose-in hovering and sideway hovering. This sport is REALLY cool..

Thanks Phil I appreciate it!

I checked the sense wire and it is on channel 5. There is a site for Raptors that tells how to setup a 401 on a Futaba Super 8U. The part about one side at 80 and the other side at 20 = 60%? Other side of what? Do they mean normal and HH, one side and other side? Please clarify this for me.

QuestJinn,,, once you get the wag fixed you will find you love your Falcon !!

please don't give-up on her yet,,, I think your problem is in the TX, try a different channel and see if a different ATV setting changes something...

alwallash, I would like those part #s', but I have gone through the slop thing to. Sounds like you had the same issue. At this point, I will change the parts out just because.

Jim, I also think that it is in the Tx. But I can't figure out what could be wrong.

Hey man I live in your area and I bet the problem is not with the Heli it's with the set-up in the Radio,the RX, or the engine/pitch curve. You're getting a lot of info here and it should pay out, however, if you don't know what you're looking for than this amount of info is a waste. It sounds like you need to get with the right people and let someone who has a lot of experience with that bird set it up for you. The person who sold that heli to you probably set that bird up to fly his set-up and not yours. Not to sound mean but everyone has a set-up that's purely theirs...Let me explain, you said that you're starting out in the hobby, okay you're probably flying with some type of training skid and I could be wrong. You need to set that bird up a little different than say someone who's not flying that setup. Also, they might have had that bird set up to 3D and at this point you need to be hovering or doing more of a FAI setup.

Second, you have a lot of resources in the area, some good and some not so good and I won't elaborate on whos who. Get with the right people and trust that you will get the right results, i.e. the people over at MC2 International. If you worried about spending the few dollars to get that bird running properly and to have someone teach you how to set up than the alternative is crashing and spending money on parts. Listen, I've been flying for two years now and the experience in the area has paid out greatly, trust those thats been flying for 20 years they might have seen the problem before and guess what...they sell those kits.

My last thought, try not to look at others and gauge your progress because you will always come up not to happy with what you have accomplished. If you want to sell that bird, I will be more than happy to take it off your hands, because that bird flies like a dream when it's set up properly. So get with us man, come out to Chesapeake and let the group give you a hand. If you can't make it out then get with Eulace and Norvin over at MC2 and I would bet that in no time they will get that thing working the way you want it. If you're wondering those guys run MC2 and everyone in the area at some point has to ask the guru (Eulace) for help...He's been around a while and by far the best pilot in the area. Hope I helped

I’m starting to think that there is some minor design (vibration) problem causing this heli to wag with a 401 and even a CSM540. Normal mode works great but HH wags like crazy. One option is to fly in normal mode only. I have a problem on my Fury and on QuestJinn’s Falcon; as soon as we flip it in normal mode the heli starts spinning. I remember reading something a while back on how to stop that, can anyone share a fix. QuestJinn could get some enjoyment out of his Falcon because too many people have looked at it and no one has fixed it. So rock solid “Rate Mode” may be the ticket.
