I think XTREME is haunting this forum; and taking notes! !

I installed the XTREME upper head which I knew separates the distance of the upper and lower blades by another 5mm or 1/2 centimeter; 1/4 inch, whatever, to prevent blade clacking, and flybar clacking, but as an added bonus, they have limited the flybar travel by I'm guessing almost 10 Degrees! !

And this was no accident; they purposely lengthened the upper head cap limiting the travel uniformily on both sides.

I put a stock flybar on, gave it forward elevator and kept the stick stationary; I didn't let the stick budge, and the heli just kept going, going, going without any hesitation at all ! !

This is what Soloboss has been saying all along with his experimenting with buffers to the flybars!

This is important, because if You are using Your modified shortened flybars, using lighter weights, and coupling this with less travel of the flybar using the head I'm describing, will cause the heli to run away from You, and You can't stop it ! ! It will fly great until You get brave and hit the throttle some more and inertia takes over, baby ! ! It's an inevitable crash. I've had it happen outdoors and in, and couldn't put my finger on it until now.

This new head was designed for the stock flybar to give You Your cake and eat it too; the rock steady hovers You want that the stock flybar gives You, and the dismissal of the added burdon of dealing with the hesitation on forward and backward movement from overtravel on the stock set up. You know; the heli would fly forward 20 feet, then stop when the flybar catches up with it. It used to be one way or the other, and You had to choose.

I can use my slightly shortened flybar with the new head, but have to have 3 collars each side (as per Soloboss' suggestion) to get it to behave as good as the stock flybar with this new head. I am still going to use the modified flybar; just a little longer, a little heavier as I really like being able to put the carbon fiber tubing on (another Soloboss idea) it to prevent the flybar bending all the time. I also like the looks a whole lot better. I just have to experiment some more. All it takes is $ $ , right?

Gary I love you like a brother but quit with the awesome news already!!!! If I buy anymore helicopter parts this month the wife is gonna kill me and how on earth am I NOT going to buy this now???? Your gonna have to tell her cause if I try to as for forgiveness one more time on parts I'll be living in the garage! If it was summer that's not a bad thing but it's winter and there is no heat or insulation in the garage!!!!

In all seriousness....WOW a manufacturer that actually listened to what we had to say and did something about it! If Xtreme ever came out with their own heli I'm thinking I would buy it without question! If you guys at Xtreme are reading this please please build a coaxial, a fixed pitch then a 400 series.....PLEASE!!!!!

LOL; Boy, We both have the bug. . . bad ! ! !


"XTREME 400 with brushless Motors ! ! "

So the extend upper shaft is the way to go? That is one of 2 Xtreme upgrades I haven't done yet. The other one being the Xtreme Flybar.

I'm not going to make any recommendations just yet, just observations and first impressions, but I like mine (so far) and what have You got to lose?

I personally think that extra height is going to all but eliminate 3 problems that are inherent with E-Flite's stock set up.

1) No blade clack due to the increased distance

2) No flybar to lower blade strikes because of the increased distance AND limited travel of the flybar, so no need to shorten flybar.

3) Rock steady hovers that only a longer (as in stock) or shorter with increased weight flybars give You without sacrificing good forward and reverse controls; I haven't seen the start and hesitate motions I had with stock.

I really like the looks; it's kind of a titanium color; maybe a shade lighter. It uses one screw that is long and goes all the way through. It's aluminum, as well.

The heli is starting to look like a real one with all the mean metal on it.

What color is the head? Is the shaft replacable like the Efilte?

It's a satin, slightly darkened aluminum finish looks alot like titanium, and has removeable and replaceable shafts. I don't know yet if the stock inner shafts will work; as I haven't had to replace the inner shaft yet; haven't bent it yet.

p.s. wouldn't it be cool if the shafts didn't bend as easily as the stock ones; that would be cool.

Do you have any pics of it?

Have you used the Xtreme flybar, yet?

no wonder its less forgiving, should i add another weight to each side of the flybar then? will this still let my have fast forward flight? or will it stop after 20 ft?

butters,

I have 3 on mine and it behaves like stock; and it still goes forward without hesitation. I haven't been able to go outside, yet (winds) but it moves pretty good indoors, and I have very good stability with the shortened flybar with 3 weights.

Slap the stock back on and You will see what I'm talking about; because it has no hesitation, (that I could see) it builds speed, even with the stock on; so experiment.

I just hate how the stock bends so dang easy, so I will put the carbon fiber re-inforced slightly shorter one back on with 3 weights; but I'm going longer on the flybar, now that I can for better stability, just a tad shorter than stock, but with the re-inforcement, I think maybe I can have the best of both worlds; finally.

Gary

No, I haven't. Do You mean with the lights?

I might someday; how do the paddles behave?

Goldslinger,
I haven't done the math, but from my fiddling I found that there are two ways to get stability out of the flybar. Taken to ridiculous extremes, you could run a super short flybar with a ton of weight on it and get stability. But the weight of the heli goes up - and the weight is carried above the rotors. That seems like a bad idea. The other extreme method would be to run a very long fly bar with very little weight on it. Because the flybar "tip speed" is greater (spins in a larger circle) you need less weight. And the longer flybar has more leverage.

I was going to go to a longer flybar by sliding the weight and boot up the flybar and straighten the bend. Then remove the junk and use one collar with CF tube over the full length. If I needed a bit more weight I'd add shrink sleeve over part or all of the length. Possibly, a coat of epoxy over the length of the longer flybar - then slip the CF tube over the entire length would be enough with no collar at all. If not, add shrink sleeve over the last inch or two or three or . . .
Anyhow, I'd think we can get the spinning weight that we need without the 'lump' at the end if we run a longer (but very svelte) flybar.

your thoughts?

I haven't tried one, yet. I was just curious if you or someone else had tried it.

What would happen if we balanced out the weight across the length of the flybar with 3 collars each side. Meaning one right at the hub, one in the middle and one at the end. We would increase weight, and it would be balanced? I just might have to try it....better wait till my Xtreme blades and grips show up though cause I'm out of lower blades

Dang, Stump3r,

That must be torture waiting.

What I ended up doing because of the XTREME extended head is allowing Me to do was to go ahead and cut the ends off of a new flybar, but leave it only 5mm shorter than stock on each side. Now with the hooks gone, I can add my c.f. re-inforcement (a must have) and only use 2 weights instead of 3; the extra flybar length makes the third collar on each side unecessary because You can use less the longer You go and get the same stability. I already demonstrated that the lesser degree travel on the XTREME lets You use a stock if You want without the start, stop annoyance.

So I dropped a couple of Grams or so, and it behaves like a stock flybar due to the added length adding to the gyroscopic affect (still shorter than stock), have the re-inforcement, and it weighs about the same as stock. I also won't get blade strikes and flybar strikes because of the 5mm XTREME extended head, 5mm shorter flybar each side (1 full centimeter). I'm pretty confident that the heli won't be 'crashing' into itself now.

Jeff (J-MICHAEL) has done experiments, before this new extended head came out, with sliding the weights around; start at the end and move one inward; what it does is give You unlimited increments of adjusting for balancing hover and agility.

I'm finding stock hover and very good agility with what I mentioned. Try it; You may like it !

Wow you just described my flybar! My last design was cut about the same length...can't remember exact measurement! However two weights and cf reinforcement. I didn't weight it against stock however I'm sure it's pretty close. The only down fall of the design is still the stop and go however it has never even while inverted caused a blade whack! Damn I really have to order the Xtreme head now as well. Another long wait will ensue....I wish someone in Canada carried these parts......maybe I should open an online store

Yea, Your start, stop, etc. will pretty much dissapear with the new XTREME upper head, even with a stock flybar.

Since My last post, I put the 'bullet' weights (got off a flybar mod selling on E-BAY) on the flybar I described above, and they are notably heavier, and I'm getting even better stability, and not too much less agility. I can now hover less than an inch off the floor rock steady with the new powerful blades, that before had too much downwash to give Me what I had before. My upper assy. is running alot more truer now; maybe it's the better aerodynamics or concentration of the weight at the tips, I don't know; but I like it ! ! I think I'm leaving it as is; for now.

I would like to find more of the bullet weights without having to buy the whole upgrade. They make the flybar way too short, and I hated it; but luckily, I don't throw anything away. I'm sure they are off of another brand heli somewhere.

Gary

Do you have any pics of the flybar setup you are using?

I'm at work (ha, ha) right now; but I'll take some pics tonight, and post on this thread for You; Dragon.

Also some video of My installed homemade lights with strobe; will post that on the 'Stupidly simple light' Thread I started a few days ago.

Gary

Thanks..........................

Here You go.

Well, I just decided to take the plunge and install the Xtreme Sport upgrade on my new CX2. I am perplexed. It does not fly well.

I've read a lot of te posts on this thread. When you guys upgraded, was it this bad right off the bat?

http://s215.photobucket.com/albums/c...t=3b7de045.flv

I couldn't control her and she had terrible TBE. This wasn't a case of me getting crazy. All I was trying to do was hover from a takeoff.

Should the blades to tight or loose in the holders?

That's the other thing, my setup now with Xtreme has less lift than it did before. Doesn't make sense...

Any thoughts guys? If I can't figure this out, I am going to start removing the Xtreme upgrades one at a time until I find the problem.

Hey, Bry.

Did You read my tips? http://www.rcuniverse.com/forum/m_6554024/tm.htm

I bet the flybar is binding or You have the blades too tight. The blades definately need to be a little loose and it will self align; it will be uncontrollable with them tight because You can't get the alignment perfect enough. You can get real close, but only itself can get it perfect; so loosen up !
