@hams, the problem is the length of the links due to the head being too high. If i had a way to stiffen the link extensions (mine is only threaded rod) for example a carbon tube over the threaded rod like a lot of tail push rods do, i can probably do away with the follower. As is i don`t want to risk it without.

so step 1 see how it works like this, step 2 try stiffen the links with suitable carbon tube and try again. i`m looking for the tubes right now.

@helinewby i got the whole DFC upgrade from fast-lad.co.uk measurements will have to wait a bit until i`m finished at work.

flew it today twice and it`s working ok. Had to redo the angles and settings with the microbeast several times tho, the swash leveling remembers the previous position, once you level one channel and switch to the next it returns to the previous position not the newly stored one. that threw me a fee times.

the measurments arwe from center of the swashplate stud to the center of the pitch arm is 93mm from the top of the original ELY-Q plastic eye to the end of the Align pitch link 43mm (thats the visible length of the threaded rod) when i unhook the swash follower then i can twist the swashplate about 5° to each side, thats too much i think at least to much for me to try flying without the follower.

So to get the full benefit of the DFC links 2 things have to be realized:

either lowering the head
or using something stiffer than threaded rod.

The links look good, better than the plastic links but thats my personal oppinion, is it worth it ? probably not if you look for any difference in flying performance (unless you lower the head), if you like shiny metal on your head then probably yes

MB, what is the exact size of thread needed to screw into the DFC bearing joint?

I can take a look around and see what I can find. Any way to show the bolt holes space difference between the two heads. How hard would you say the task to drill the DFC head to fit the COMP shaft would be?

I cant find the DFC kit in stock anywhere, let alone the parts for it. All the experiments have to be done by you at this time MB

Cheers,
Raven

Raven, I did drill the DFC head to fit the ElyQ Shaft. The difference is only about 1,5mm it doesn´t look very nice but works.

I installed the original spindle and grips to the DFC head but with the grip bolts tightened down fully on the spindle there is a play of about 1mm left right with the spindle. it´s odd, the outside width of the head is the same, maybe a shim behind the dampeners, i have to check again.

The thread is the same as on the ElY-Q flybarless pitch links M3

i guess everyone took the DFC kit out of their stocks as there is a general Align recall

got my self some 6mm OD and 3mm ID carbon tube today at the LHS and finaly had the means in hand to stiffen up my Pitch links.

With the Carbon tube over the threaded rod the links get very stiff, and all the twist thats still possible is coming from the play in the bearings of the pitch link on top and the flex of the plastic eyes at the bottom.

so i finaly decided to try without the swash follower.

The flight wasn`t pleasant !! But not because of the pitch links but due to the freezing -10°C and 15kts of wind (talk about wind chill!!) i flew only 1/2 a tank because my finger tips started to freeze (as in turn white and burn) but it worked flawlessly even in hard manouvers with lots of cyclic and pitch there was no visble tendency of the heli to react weird/ or any interactions as it would if the head got out of phase.

So thats a success

What i would now like to see is the head a bit lower, as that should make a real difference in flight performance when the rotor disk and teh CG get closer together.

i`ll have to try again with the Align head, and maybe i have a friend of mine machine me a new head hub..

DOH i can`t believe no one caught it i was searching for some parts today and a main shaft fell into my hands.. and it looked different... shorter than the one i have! Darn i mixed up the main shafts and flew with a flybar version shaft !

So after finally getting the right parts installed it looks like the attached pics. much better, the grip extension is now only 22mm (+5mm lock nut). That properly stiffened things up too.

I've noticed this as well. I wonder why that is?

Raven that is the stock head and FBL shaft from ELYQ I doubt there us any problem with boomstrikes with that the blades are still about 155mm from the tailboom, so I think you could lower that even further with a custom shaft. Then it would fly different too for sure.

I'm really curious why the FBL main shafts are no where to be had...

FBL main shaft
Ah, just not use to seeing the comp sit so low.

I have the standard fb shaft...was the shaft pulled off market because of a rare problem of boom strikes...

I have only read and seen this happen one time to the 90comp FBL

no problems
Never known a elyq 90 To boom strike. It just doesn't happen...while the dfc head is cool looking it is not really needed. But I do like the lower profile..
