Like I said Fid, I am a beginner so I have to get my vet friends to help. I want to be sure that I have everything correct. I may not know what I am looking at. I am going to drop the heli off with Ulis, my local heil-shop owner and flying pro to check the whole heli and radio. I will let you know what he finds!

My Posts This: Topic  Forum		Doing the right Thing

Leaving it with ules (Eulace) is the best thing you can do. I have the funny inclination that the gears in the tail might either be put together backwards or striped. Eulace been around for a long time, to the point of looking at something and telling you why it behaves the way that it does from an engineering stand point. I might note that he is also a Heli UAV engineering consultant to the military. It does you well to let him give it a go, I'd bet in one hover he'll have that thing working properly.

On more than one occasion Ules has amazed me with what he knows about helis, stuff that I wouldn'd have even guessed at. I'm sure if you ask the locals everyone will tell you the same thing. You should see some of the exotic birds he's got over at the shop, those are the ones he just play with....the working birds are at home, multi-blades.

Don't tell him I spelled his name wrong. But I have been dealing with Eulace for a little while. I buy his fuel, and other things from his shop. He has looked at it before, but he didn't keep it. We were in the field when he looked at it. And it's not the gears, Norvan {I hope that's right} and I took the tail apart and the gears are setup right. So it's something else. He said it should be ready tomorrow, I hope so!

My Posts This: Topic  Forum		Looked at it Today

He QuestJin, had a chance to look over your bird while it was at the shop today. Several things I noticed and I'm sure you're going to hear about this later.
First, Your Falcon had an incredible amount of slop on the tail, upon further observation it apeared that the tail pitch slider and plate is very loose. The only fix in this situation is to just perchase a new one, as this is the best and the cheapest solution. You could try and repair the exsisting one but it's worn out and you don't need to play with worn out parts.

Second, I notice that your tail gear box shift about 1/8 of an inch from left to right, I tighten it just to see if the this would fix the problem and it still rotated. This is a quick fix, all you need to to is probably tape the tail boom and then reapply the tail gear box.

Third, The ball link connecting the rear servo rubs against the servo wheel. That need to be fix, and again that's a quick fix. You can either reverse the ball on the wheel and/or remove the amount of wheel interfering with the ball link. You also had a considerable amount of binding on that whole tail link and I didn't get a chance to look at what's causing that. I'm sure Ules (Eulace) will find it.

Forth, I inspected your tail pitch plate and noticed at some point it was rubbing against the tail blade grips. Again, this problem will be address with a new tail pitch slider assembly.

Fifth, This is the most disturbing. I inspecting you servo, the wiring feeding the servo is brown and discolored. This is not a fluke or caused by some type of oil or die. The problem here is that the wiring is getting way too hot. Not sure what caused this and many things I've seen to suggest a lot of issues. I'm tempted to believe that the wiring is getting to hot because the gyro is working overtime and that would explain the hunting you discribed earlier. Secondly, it could be cause by the fact that the servo is just starting to go and there is a lot of new resistence down that circuit path. Lastly, it could be all the zip-ties you have securing the wiring, not a bad idea but the ones you have are too tight, and I think you might have some chaffing against the side frames. I'm sure this will be address when Ules sees it. I'm not a saint by no means but I would never use a wire to secure the extentions as I found out that this could be a potential problem with RF hits and whatnots. The simple solution here is to secure it in such a way not to induce stress at the parts being joined and make that connection reliable. Heat shrink works fine in this instant.

Sixth, There was a lot of dirt and debris on you tail blades. You have to remember that this is the business end. Like the main rotor, you want those blades as clean as possible so you don't have more drag than lift. Not that this is as big an issue and I've seen a many of pilots fly their birds with the more than caked dirt on the tail blades, however, at the expense of reduced proformance. I happen to believe that a clean ship flys clean and crisp.

Last and I'm sure I didn't get all the issues. You might want to take those wood blades and rebalance them, just for S-A-G (sh_ts and giggles). Carbon on the tail...wood on top...Hummm....Cmon man! I'll give you the benefit of the doubt, you were waiting until the bird was flying good...Right? Welcome to the Dark Side....See Yah

My Posts This: Topic  Forum		QuestJinn,

Your Falcon SE has thrust bearings in the tail rotor grips. If the
thrust bearing is put in backwards, you will have tail wag reguardless of your yaw rate or gain settings. If you haven't
already done so, remove the thrust bearings and make sure
the race with the larger inside diameter is assembled onto
the tail rotor hub first.

Good Luck

I did check that out. The bearings were in right. Another Century rep had me check that.

LUNITIC, I got all of that from Norvan. And about my blades, like I said, it is MY FIRST HELI, I AM NEW! What, am I suppose to buy all upgrade parts as soon as I buy the heli? I have only been flying for two months! Can I get a break please?!!!!!! Along with my pocket! But they are on order!!!

My Posts This: Topic  Forum		Century part numbers for Falcon T/R upgrade

QuestJinn,
Looks like you are making progress.
I had a vicious tail wag no matter what HH gain setting. Tried three gyros. All were the same.

I also found slop in my Falcon T/R blades due to the pitch plate and pitch lever system.

I replaced the following parts and the tail wag went away nicely.

1) Machined pitch plate (CN2282B). This is a sweet NEW one-piece metal pitch plate with NO slop when used with item #2..
2) Tail pitch lever set (B.B. type) (HI3102B)
3) Ball bearing 3x6x2.5 flanged (2) (CNBB0360F) for item #2
(if you go with item 1, you need items 2 and 3)

(if you do get these ask me for instructions as it is a little tricky and could be done wrong. A washer comes with item 2 and needs to go between the two bearings (item 3). You will need to drill the hole to mount the pitch lever machine screw slightly larger. Or maybe you could look at the manual for the Raven online.)

The head Asian guy (Peter) at Century recommended NOT to use carbon T/R blades. "Too stiff". He recommended clear plastic ones (HI3099).
I bought these but did not need them after replacing with the upgraded pitch plate and lever. Someday I will try them just to see if I can tell the difference.

I changed to white fiberglass main blades to carbon ones. The fiberglass blades were out of balance every which way on a Koll balancer.

Falcon flies nice now. Flew it this morning. I can hover tail or nose in, and am just learning sideways hovering and starting to move around more. Taking it nice and easy..don't want to mess this bird up now that is finally flying well!
Good luck,
Al

My Posts This: Topic  Forum		Is this a Falcon SE V2? I have NEVER heard of tail rotor slop on this machine. If there is any it would be due to a flex in the pushrod.

The tail grips have 2 radials and 1 thrust. These grips are smoother and more precise that the ones on my Furys and they flew GREAT!

As for the pitchslider there must be some building errors or something because that is the EXACT same pitch slider assembly as the Predator and again it is slop free. I wonder if the lock washer was pressed on properly providing a snug but smooth assembly.

I realize that Century came out with a CNC pitch slider assembly and I have it on my Predator. But, to be honest it is no better than the stock assembly as far as slop goes.

I have been running a GY-401 gyro on my Falcon converted to Raven for over 350+ flights in non-AVCS and AVCS with no problems except a pitch travel range early last year before they redesigned the pitch slider assembly. I fly my heli backwards more than I do forwards and I run the RotorTech 92mm CF tailblades. I can tell you that without a doubt that this tail system is just fine. If you are having problems with your heli it is DEFINETLY a maintenance or building problem.

My Posts This: Topic  Forum		Falcon Tail

I have the same questions as Lift.

This cannot be a Falcon SEV1 or V2, it must be an old standard Falcon 46. I have both the V1 and V2. Both are very high time units and the tail rotor and control systems on both have far less slop then my MinAir 60's! If your tail rotor blade grips do not have two radial and one thrust bearing in each, if your tail rotor control bellcrank does not have bearings supporting it top and bottom then it is not an SE but the old inexpensive Falcon 46 which was basically a 46 size Hawk II.

From reading what Lunatic has found on your Falcon I would be prone to believe it is not the SE but the old 46.

My Posts This: Topic  Forum		At that point!!

The heli is about to go! Eulace and Norvan had the heli for two days and changed out all kinds of parts. There is another posting here with a different guy having the same problem. I have seen numorus postings on RR about people having the same problem. That Raptor is looking better and better. Reguardless of what people say about how it flies, I haven't seen as many complaints about problems with it. I can calm it's flight patterns with radio setup and flybar weights.

This has not been a desirable experience for a newbie!

My Posts This: Topic  Forum		You Gotta Step it Up bro!!!!!

QuestJinn,
Well take it for what it's worth but MANY of us that have been on RR for sometime used to fly Raptors. If they were THAT much better why would we be flying Falcons and Raven's.

My tone may sound rude on this thread. If so it is a result of buiding or setting up 9 of the Falcon SE V2/Raven 50 helis in the last year and NOT ONE of them has had any form of slop in the tail, head, or anywhere for that matter. It may have been fine at first and your problems wore some parts out but I can tell you emphatically that just like we all said in the beginning there is something wrong with your setup and not the heli.

If you come on here and ask for help you need to actually investigate the recommended areas. You can't dismiss everyone's suggestions as "I checked it.....it's fine". You are lucky that this heli didn't crash!

Lunitic noticed:

Let me say this. Go ahead and get a "different" brand heli. If you think this kind of building/maintance is going to make a Raptor fly better for you then you are in for a big surprise. I'm not trying to bust your chops here but rather to remind you that these machines require careful dedicated attention to detail. Anything less would indicate you would be better off flying planks.

Don't get offended.......get in the game and work a little harder and you will succeed. No matter what heli you have! I personally want to see you get that Falcon in the air and enjoy it. I wish I was in you area and able to help you out. Hang in there and don't give up. When I got started my Raptor 30 almost drove me out of the hobby. I had a bad one that had all the problems that you could possibly have. But....I stuck it out and learned alot about heli building and maintenance because of that experience. Let this experience be your spring board too!

My Posts This: Topic  Forum		QuestJinn,,, don't think I'm mad at you,,, but,,, you can't be upset with your Falcon, as you said you are a newbie !! and there is so much for a newbie to learn about on these things that you will be learning for years and years, ask Oldfart, even though I thought I had my main rotor control system as smooth as it could possibly be, every time I tear down my rotor head and put it back together I get it smoother and smoother every time !!
there is so much to these things that it can be upsetting and stressful, everything need to be setup just right to have it fly nice and smooth, soon you will be learning how different setting and changes will make it feel on the sticks,
and as far as the Raptor, I would get that out of your head now, I had a Raptor, and maybe the Raptor can out fly a Falcon right out of the box, but it couldn't out fly a Raven right out of the box, that's for sure !! and if you don't think the Raptor has as many problems, well, that's flat out wrong !! if you researched the Raptor here on RR you will find the Raptor V1 is loaded with problems, and as far as quality, if I had crashed a Raptor the same 6 ways I crashed my Hawk and Falcon I would have had to replace the Raptors frame 6 times, with the Falcon and Hawk you just replace parts and reuse the frame, in the long run you are much better off with your Falcon, you just don't know it yet !!

My Posts This: Topic  Forum		I use century product (hawk4) for learning how to fly.....and yes it is have a lot of problem with the design.
and now i move to r50v2.....i cannot find 1 problem (yet) with this choper....
but anyway i dont care if century have a lot of problem or not...still....century was my 1st choper....i love get in this hobby.
and first love never die

at last please just enjoy this hobby without compare with other brand if you are newbie and you have a lot of problem with your choper, i think thats good idea too...so you can understand about all the problem that you can fix it later on with your other heli.
