JR Heli Vibe - Airskipper - Sylphide - Venture > Flybarless Vibe 50 ??

I'm thinking about going flybarless, for one to save weight and the other to speed it up a little. Has anyone tried the Vibe flybarless yet, and what system do you suggest. I bought a 600N and set it up the same as the Vibe 50 I have and its comning in a 1/2 pound lighter than the Vibe and you can tell a big differene.

But the 600N doesn't track like the Vibe, I was just thinking that loosing the flybar might just level the playing field as far as weight, speed and power goes.

Lets hear your ideas.

I have that in mind too , I also have the idea of how I'm going to do it , I tried some Mikado blade grip spacers and the Geometry was fine , I'll fly it with flybar first but I really like the feel of My T600N with Vbar so the Vibe should be a winner with a Vbar.

Could you not use the stock grips as is and just add the V-bar

Forgive me, for the question but I've not researched the how to on flybarless dos and don'ts, that is why I threw this question out hear to find out from you guys what really needs to be done.

From what I have seen it looks like most are removing the flybar, seesaw etc, and trimmimg the washout arm off on one side, but I'm sure there is more to it than that.

I think the stock grips with a spacer (long ball stand off) would be fine. I'm going to drop my Kasama head off the T-rex on this for my V-bar conversion only as I have it spare. If not I would use a stand off.

Not a lot more to it really, you need to move your balls in on the servo's and achieve a distance of around 33mm from centre of hub to control ball on the grip. You want to aim to get around +- 15 degrees with the V-bar between 60-80 on the collective comp.

Are you serious

Mine is exactly 46gr heavier (thats less than 2oz) with the same setup. Now if you take that the canopy is over an oz heavier, its good for me...

Yep,
1/2 pound, Its hard to out fly something thats a half a pound lighter than you are. I can get them at the same weight if I remove the rear fin and the entire boom support along with the canopy.

As far as open circuits the Vibe takes it hands down with handling and tracking, but close in ground pounding 3D, even the Vibe can't out fly 1/2 pound difference.

225gr difference is too much in my opinion however you can shave away at least half of it or more if you dump the horizontal fin, replace boom supports with carbon version, throttle to mini servo, tail linkage in front and back with 5mm carbon, vertical fin from a 600N... that alone will give over 100gr.

I heard a rumour about a company that is comming out with a titanium mainshaft at less than half the current weight so thats another factor to consider.

I have thought of changing the tail support to something different, but I'm still wondering if it will be as solid of a support with something other than whats on there, sometimes saving weight comes with a give and take.

I have an OS61 and a OS70, and have consider putting one or the other in with 610 RT blades and then I wouldn't have to worry about over loading the head, but then you get into gearing issues etc.

Well you know, this might be a little off topic but today it was very windy so I couldn't do much at the field so I just entretained myself doing simple tic tocs for full 4 tanks... I must have done around 400 at least. While I was doing them I started to play with the collective and cyclic throws i.e. increasing one and decreasing the other and vice versa. On my third flight while I was already throwing up from all those tic tocs, suddently I realised I wasn't hearing the engine changing in tone. I was only hearing a slight bite while the blades were changing pitch. Interesting is that I figured out you don't need half the pitch we use doing tic tocs and still keep them speedy and tight. When I got home, I downloaded the charts and voila... half of my third flight and the whole fourth flight looked like I was hovering but in fact I was doing tic tocs the whole time!

Anyway, Just wanted to leave this comment since I'm only using 20% nitro and with a YS50 you can do power demanding maneuvers without overloading the head if you move the sticks properly.

I agree,
Its just nice to have them a little more forgiving, but in the long run it will make a better pilot of of you if you learn how to manage the collective.

Didn't you use the 600N boom supports on your Vibe? are you still using them.

I looked at the 6ooN I have and the boom supports just don't look to be rigid enough, but I guess if they work on the 600 they should work on the Vibe

Yes I did and they are actually more rigid. Problem is that it made the vibe's tail feel like the 600n one. I couldn't believe it myself but those simple boom supports influence how the tail behaves in flight. The lack of flexibility transmits natural engine vibration in a harmonic wave to the tail which then starts feeling a little mushy and less precise. Once I removed them and put the stock boom supports, the tail immediately locked in... wow!

I'm now waiting for a set of quickuk carbon boom supports which are a little thicker but a little more flexibe to try them out.

I guess Align stuff on a Vibe is a no no
