I have a sky tach.
I have a freind who tachs it for me.
I also use the speedup gear.
I also run smaller blades and more pitch.It works you should try it.
I have also talked to heliworld and the headspeed i run isn't dangerous. They said ther reps run simular headspeed.
And as i said before i only use idle 2 when doing hard 3d.
You should see the headspeed guys are running on the 600 eletrics.2500 to 2600 is common.

Okay guys.

The biuld is moving smoothly. Kind of. I accidently isnstalled the lower aluminum frames inside out wich cause all kinds problems untill i figured it out. One of those "DA" moments. However, as i continued the biuld i noticed that the washout base is really tight on the main shaft. The swash plate moves like silk but the washout bas is tight. I tried oil but it didn't seem to get any better. Any ideas?

Other than that, the heli looks really nice and a REALLY solid platform.

EDIT:

I got the washout moving freely along the shaft. I curled up a piece of high grid sand paper and stuck it in there. I slowly turned it about 30 times and it moves fine. The washout guide pins slow it down a bit but i can easly move it with my hand now. Before it took alot of force just to move the swash.

Sounds good. A few flights and it'll loosen up a little more.
Yeah the directions could be better.
I'm sure you're going to enjoy your new heli.
Mine have been bullet proof.
The few problems i've had were caused from flying in subzero temps.
In the summer weather no problems.
Plastic just doesn't like the cold
It's not in the instructions but there is a small hole in the mainframe where it clamps the boom in. Drill through the boom and install a short screw.Will prevent the boom from slideing out and disengageing the drive shaft.
Also the tailslider retaining nut likes to come off so disassemble it and jb weld the bearings and nut to the collar.I have had red loctite fail here even in the summer.Make sure you do the bearings aswell so if the nut does come off the slider will stay together.

Okay, so i did 4 hours of strait biulding yesterday. I got pretty far. Everything is installed and setup except for the tail and throttle servos. I ran into a few problems. First, the torque tube apeared to be almost to short for the thing to work. I must have tried it 10 times with no luck. So i typed in "boom short" on the search for this forum and the first thing that came up was a thread on the very topic. Turns out that you just have to push a little harder and it slides right in. The head is just amazing. It is SOOOO much better than the Gohbee head in ease to setup and control distance. First off. I ordered the long heavy duty Dubro (plastic) servo arms for the s3050's on the cyclic so i could get the most out of the head. This ECCP setup is SWEET. It has 0 slop and is just so easy to setup. The next thing i noticed is that moving the pitch seemed to have little interaction with the alerion and elevator functions. I could move the blade to plus 14 and turn the stick all the way to the cornor and without any binding. I thaught that was sweet. The stinger head ran into binding issues at around 10 degrees of pitch and extreme cyclic positions. I haven't goten to the tail yet but it is really tight. Am going to take a closer look at that today.

Yeah forgot to mention the tight boom . not all of them are tight just a few.
I also run really long serv arms on my ravens it does give you more pitch wiht out binding.
It is definitley a good head desighn, I have pulled 16degrees in my raven withan os 61 in it. The head stays slop free, and with some different length ball ends, or the cnc adjustable mixers,it has alot of tuneability.
You know i hear of people haveing interraction problems on eccpm.And i wondered what they were talking about, but i started on century and never experienced that issue .I guess i'ts those other brands that have that problem.
As for the stinger head. I just got a gohbee Phazor 600 2 weeks ago. And aparentley they fixed there head problems. Because the Phazor uses the same head as the stinger and mine works awesome, Although it is 120 degree eccpm with cnc push pull bellcranks with generous travels. I can pull 17/17 pitch with no bind or interreaction.And it tracks great and with 3D paddles it's cyclic is as fast as i've seen.I heard they improved there grips though.I just installed some taller gearing and full metel head on it to take the extra headspeed i'll be running,Havn't flown it since though ,we just got hit with a blizzard.
IMO they are both great helis.

Your phazor uses a 120 ECCPM swash wich is what my stinger needed. I always felt that the mechanical setup just flatout sucked on the stinger. Instituded way to much slop to the system. It was frusturating because the head stayed tight but the controls were really mushy. Anyway, i did get some binding at extreme cyclics full collective around 14 degrees. No problem. I just can't crank the stick all the way back at -14 wich i never would do anyway.

Next step is setting up the tail

That makes sense the new 120 eccpm system is very tight,Plus the bellcranks are quite long and i think that is where the extra pitch range comes from.
Of all my helis I've never had a mechanical setup .But just looking at all the pivots and links and extra BS i can see where a lot of slop and loss of feel could happen.
I'm actully just finishing up anew heli myself, Just got a new swift in the mail yesterday and all thats left is to install eletrics.
Doing some experimenting on this swift i built a double maingear for it and I'm installing an 8s power system. Should be awesome. Hope it works the way I've been thinking it will.
If your working on your tail don't forget to glue the slider retaing nut.And also I've fould 1 .5mm shimm behind the output shaft gear helps to keep the gear from stripping in the event you tap the groun with the tail.Got that tip from joe at heliworld aswell.

Okay, i started up the new raven and everything was really smoooth except that the tail was wagging for whatever reason. I have the 401/9254 combo. The more i lowered the gain the slower it wagged. It was really weird. Any ideas?

Thanks

Any binding in the pushrod ro the slider?
the slider nut can come loose and cause this also.
A couple times I've seen lateral play in the gear box cause this aswell.Is it a fast or slow wag? the 9254 on the 401 uses a pretty low gain% on that heli.Also how far out from the center is your servo ball with a fast servo like that you don't want it out top far.
Is the motor tuned in? the raven runs a 5 to 1 ratio on the tail gearing so i have found it to be sensitve to the motor foustroking from running to rich.

thanks for the imput centuryman. Turned out to be these two small spacers that are placed between the radial and thrust bearing in the tail. Oldfart poiinted this out to me on the main forum. THANKS OLDFART.

Maiden is tomarow. I can't wait.

That OLDFART should be a rep, with as much as he knows about century helis.I think I'll just cut to the chase from now on when i have questions and just pm him
With any luck i should be maidening my new swift 16 with an 8s power system tomorrow as well should be balistic with 8s power in a 5.75 pound heli with 550 widechord blades.

Well, i got the maiden in today. The conditions were less than ideal as the wind was very strong at the field. I would guese in the 20mph range. Well, all i can say is wow. This is by far the smoothes bird i have ever flown. It spools right up, doesn't shake at all like the stinger. The tail held great for the wind conditions. The as ALOT of pop with +- 14 degrees of pitch. Althoug one needs collective managment to prevent it from bogging down. For such high winds the things was silky smooth. I can tell the difference the 4mm flyber makes. Just amazing. The heli flips on a dime it seems. Probabley because of the ECCPM system. Just REALLY smooth flyer. I did two flights before the 401 starting having alot of problems with the tail. I did a couple flips but the wind really through me off so i stopped. (Not to confortable with aerobatics and wind yet). Also, man the fuel tank holds a butt load of fuel. I was getting in the 12-15 minute range with 15%. I am thinking of moving to 30% soon.

Skip the 30% fuel and try the 15 mixed 50/50 with the 30%, Easier to tune and less smoke. the engine will thank you for it in the long run. Now here come the 30% guys to give me a rash of sh&t for the mix!!!

If it doesn't fly sell it!

Yep, my company is the distributor for Century Products in Canada.

It would be great if Century USA would provide the same knowledge on the forums to all of their customers...but until they do, I guess Canada will have to provide it.

Has anyone ever noticed the high percentage of Canadians on this Century Heli forum

Cambo, mix it in the jugs you have, pour 1/2 the 15% in the 30% jug 50/50 and adjust needles for temp/muffler your using. And Ive noticed something also, Just as OldFart mentioned YES High number of Canadians on the Century Forum. Means that Century is also good for cooooold weather or Canadians are smarter than most. maybe a combination of the 2!!

If it doesn't fly sell it!
