E700 Head Link not 90 degrees

[Victor-sp]

Thanks!
It is V2!

According to a post on Facebook today by thunder tiger you only need parts 580, 6048, and 6049 to upgrade. Can anyone confirm?

Yes, I confirm, that is the same thing that I was talking about at mypost reply #37 page 2

Wonder if more people have flown old and new geometry and could elaborate on the difference in flight performance?

per Nick M. on facebook-
"Hey everyone with E700s, just a quick reminder on the new head parts for the E700. All three V2 parts must be changed together to work properly and to get the right head ratios/travels. While the head RATIOs did not change-> your pitch and cyclic values will remain the same for a given swashplate deflection, we changed the distances (equally to eachother-which is what kept the ratios the same) of the mixer arm and grip lever simply to allow for an ever so slightly more linear control response from 0- +/-15(+) degrees and for more mechanical leverage on the grip control so the grip links and mixer bearings will last even longer beating on them day in and day out. The grip plates also have increased in width a bit so they can withstand tip over autos better, etc. The new grip post zeros out the delta which for those running soft dampening and extremely low headspeeds will get a better control feel at those RPMs.

Those who fly tight dampening you will not see a change with the new grip post as without any teetering effect, delta in the head has no effective response or blade/control input...

Just again, these three main parts, the control lever, grip lever, and grip post all should be changed together. If not, the head ratios will change and your cyclic and pitch values will be very strange.

This is not a critical thing to change at all, just more or less a running upgrade that when the next time that you have to replace any of these parts you can upgrade to them. The old version functionally flies just as well, but for long term these new parts should last even longer for less maintence and tolerate minor tip overs etc better."

I have the V1 head on mine and have noticed the heli to be very sensitive to elevator in forward flight i suppose pitchy as some have described it compared to my other models with zero delta.

So is it confirmed that the upgraded parts will cure this?

What fbl controller you using?

Mini V Bar 5.3 Pro very similar settings to my other 700 size models which are Align 700E DFC and Logo 700 Xxtreme.

Did you set up the swash angles and distances correctly? It may be likely that you have the 120 degree swash defaults in your set up. In the swash set up portion you need to manually change this under the expert tab. For distances use 72 100 100 and angles use 270 135 45. You need to do this or you will have a pitchy elevator response.

No i set it for 140Deg ccpm using settings provided to me for this bird but i will check the numbers against yours.many thanks.

[trickybit]

I can't say that I've seen that. I have 5.2 on my e700 and a logo 550sx. The logo pitched up like crazy at highest speed, and the raptor does not. This is real, out of control, pitch up. You may be referring to a different phenomenon.

Just to confirm,the numbers in my V Bar under the swash section match those numbers so its not that.

I am trying different blades and have adjusted some settings in V Bar and will try again.

Thanks for assistance.

The only other thing I can think of that is different on mine is I manually set my cyclic optimizers to 40 and my agility at 100. This is in conjunction with raising my cyclic ring to about 94. Try raising that so that the controller has the max amount of room to control the model. Plus another thing I have been trying lately is to set my max cyclic to 11 degrees on the setup tab. This equals about 140 on the slider tab, which you cannot actual set unless you type in the number. I actual really like the way it flys with this set up. My bet is that you can maybe raise the cyclic ring number and that may have the most benefit. I set mine by checking at mid collective so that I did not have binding. You can easily go over the vbar default without binding, just be sure to check at mid collective.

Many thanks,i will try playing with those parameters once i have flown it again and seen if there is already any difference.

I had one of the earlier kits and then i upgraded to the V2 version. Mine ended up exactly how your photo is showing, so is that okay not to have the blade holder to swash link at an angle like this?

I'm still flying the v1 head and haven't noticed any bad tendencies, also had a few crashes and the posts haven't bent.


What is the advantage of the v2?

I think Nick posted somewhere that if you fly soft dampers at low headspeed (and thus got some 'flap' in the blades) you could get a phase effect. Others have said it was very noticeable but I don't know if they got A/B tests in.

My bet? There was a perceived theoretical issue and they were compelled to change it.

Dear friends,

speaking about head dampening - are there different options for the stiffness? I am using the kit parts, would you rate them as "stiff"? To me they feel just like this...

Thanks for any feedback and have a great one! Stefan

Can someone tell me if I messed up during the installation of the new V2 parts?

The grip links are still offset, but from what I can see Nick wrote, they should be 90 degrees with the new V2 head parts. I have installed the beefier grip plates and the longer mixer arms. I am wondering if I could have swapped the grip posts during installation, since they supposedly should cancel out the delta.

On the picture, I am holding the shorter grips posts besides the longer grip posts that are installed. Look like they would cancel out the delta if installed instead.

To summarize: The new V2 grip plate should be beefier, the mixer arms longer and the grip posts shorter? If that's the case, I have swapped the new grip posts for the old long ones during installation.


Thanks,
