Title: Ball links not fitting
Post by: troasb on September 17, 2015, 07:14:51 PM
I am one my way buliting the E7se. And I am beeing annoyed that the head ball lings do not fit the rods. I have to drill them up to even go into the treads. This is a high end helicopter and probably the most expensive it out there, so  I except much more from Synergy helicopters.

What tools are you using to thread the plastic ball links into the rods?

Definitely NOT the most expensive kit, there are plenty that are pricier. But the links are meant to fit tight so that the threads don't slip. Sometimes I use a pair of channel locks to hold the rod while I tighten the link.

If they are the stock rods, I would be worried about the rods pulling out of the links after drilling them out.  What size drill bit did you use?

I agree with Rodney, I wouldn't recommend drilling the links if you're using stock rods.

I've used the stock links... Just use a pair of vise grips to hold the rod.. Then screw on the ball links. I do however like Ralph's turnbuckles... & they come assembled together per the manual.. But either way... It's a kit.. U have to build it.

I had to use 2,3mm drill bit to make them enter the treads properly.

Yes. for sure, it is kit, but It is supposed to be a high end kit where you should not have have to drill out ball links

I think that's odd... I'm with Danny & Rodney.. Wouldn't trust them to hold after taking out meat by drilling... They are suppose to be a tight fit. I have a bunch of extra links in can send u if u like... I'll even thread them for ya... I currently have Ralph's FBL turnbuckles on mine.. Which have a larger diameter rod.. Anyhow.. PM me ur address & I'll send them to ya.. Cyclic servo to swash links right?

Thank you very much, but this is not a big deal, just annoying in a high end kit. I have not get to the cyclic servos yet.

   THE most expensive kit? Probably the Banshee if you can get your hands on one. When the new TDR is released it will be well beyond the cost of most anything available today, the speed version was rumored to be over $3500 just for the kit but no official numbers on it yet. The Diabolo is more expensive, and plenty of Goblin 700 kits are also more expensive. Mikado and Gaui have similar pricing. In fact the new Gaui R5 will be more than the E7SE. Synergy price really isn't that bad. I've had some experience with some of those other kits, and make no mistake - Synergy kits are definitely top quality.
   Matt makes the links the way he does for good reason. I've never found them to be terribly difficult, but I do use tools to hold them especially on first assembly. You should not drill them.

In my opinion you have drilled them out too large.  The standard tap drill size for m2.5 is 2.05mm.  I would be concerned about the integrity of the links now.

Is the FBL E7SE Titanium turnbuckle set worth it?

Hi Danny!

I stand corrected and aknowlegdes that there are more expensive kits out there, but Synergy is on the top shelfe of the more expensive kits, and then you should be expecting top quality, and so far I am very satisfied expect some minor annoyments. I will never go back to Align again, that is for sure! Even tough Align is the most sold rc-helicopter in the world and have good parts supply in almost any country and flyes well, but Synergy is at another world of quality and craftmanship.

Best regards

I think so.. U can adjust them without taking them off. Plus, Ralph assembles them with the manuals measurement... I don't know.. Others may disagree, but I dig'm!

Of course, they are great, but I think the kit originals should be good enough.

Here is a tip on putting the ball links on the rod end.

1.  Chuck the rod in your variable speed drill motor
2.  I use a small drill press vice and secure the ball link in the vice.
3.  Put the rod end into the link and pull the trigger on the drill motor for slow rotation.
4.  Rod threads right on, easy peasy.
5.  Reverse the drill motor
6.  thread the second link on the rod.
7.  manually thread the first link onto the rod
8.  Done.  It takes longer to write it down than to do it!!

This method works well and you get the link on the rod straight every time.  And without getting sore fingers.

So I had to resize the titaniam rods n ends straight out of the package - as per the manual's numbers. The boto-sizer works like a charm!

Late to the Dance, but I will say FBL Turnbuckles are very nice, also the stock Synergy Rods and Links are bullet proof as well, for me when I build these up, I drop a dollop of Triflo on the threads of the rods and proceed to building up the links, never had an issue,

 ** No one like building up links, and in my opinion, I would rather slam my fingers in a car door twice then deal with them, however it's a must. When I build a kit, I build all the links up first... Then I build up the Boom Supports, Tail Pitch Change Rods. Get all that done and then the fun part ( the actual build) **

sorry, I see I could've been more precise with the description - The rods came with links on them but were not the correct length, so I had to correct (twist the links on the rods) to the numbers that are in the manual
