Can anyone suggest micro fasteners washers to prevent ball link pops off?

Here is a picture with my idea.

2mm center hole/8mm flat wide washer is what I need!

This is just my opinion , I’ve been flying well over 20 years and links only pop of in crash or if something not setup correctly . Long term ware also will cause links to loosen and pop off . In my situation I would crash before any of the other issues would arise . It’s a good idea but would not be a benefit for me .

I stole it ,flew it and gave it back ;)

Always use new links when they get loose but I have seen guys use dental floss to tighten up ball links and still keep them smooth with no limit of motion

Lets do the time warp againnn !

Links that can be pop up with your hands, replace it! Don't question asks.

I agree with you. There are limited parts of Raptors laying around. I can't afford to allow this to continue. I feel like something needs to be done and to take care of the high pressure point on the ball links. As long as the mechanical points are square, I think the washer on the tail link balls will work. I still want to have a chance to land the helicopter. I have so many
Raptor parts and having rekits is a bad thing. Rekits eat through my inventories very quickly.

Thank you, I value your input. Having rekit on my Raptor supply line is devastating to me. There are only so many parts before my game is over. I can't let this slide anymore personally. I want some kind of control due to a ball link failure, I don't think I should suffer a rekit!

My wife was recording it and told me don't throw the radio TX into the ground. This gives you the state of mind I was in. I was in shock and wasn't thinking clearly at the time.

I used to do this with my Eco 8 25 years ago. You just need a 2mm washer that is just big enough that it won't pass thru the center hole of the link. any bigger and it limits motion. It was a natural for the Eco bacause the link balls bolted on with a 2mm bolt anyway.

Raptor 50 ball and ball links are 4.4 mm I believe. I tried a 5mm washer and it still popped off. I really had to force it but....

I agree 100 % that the washers are unnecessary....When I was very active with our heli group back in Rochester, NY, nobody felt the need to do that ..... that group included Ray and Kyle Stacy....

What is being proposed is not a new idea... just that I did not see it implemented by anyone.....

If the links pops off easily then replace the links....

Using moderate force to pop them off is not a reliable way to test them , IMHO

PS- many of us replaced the Raptor ball links with Rocket City links .... perfect fit after resizing a little. And unlike the Raptor links, you can do half turns to get better adjustments.....

Been there, done that and old enough to know better.....

I support your opinions! I am up against a hard rock. I love my raptors and they are not making parts for the line of Titan 50SE.

Once I burn through my stock, I am pretty much done. I will save one and hang it on the wall!

These are fabulous machines, I hate losing them!

Graupner still sells Raptor 550 links were the same and other components as well

I'm sure there's plenty of good used Raptor Parts still out here

Yeah, I am scooping up all the parts everywhere online. I got about maybe $3k in spare parts.

Washer may work on the tail since it’s a linear motion, on the swash not so much. If your binding at your max throws this is where links can fail and or pop. But as many have mentioned replace the links, the balls should last 300-400 flights before having to consider replacing. If your in need of links, I know a guy that has a few parts for most any rekit .

Here is how one of my Eco 8 buddies solved this problem back in the day.

2.2mm/7mm washers have been ordered
I believe the 7mm is the right side to allow motion and flexibility. I will post pictures as soon as I get them installed. We can discuss it afterwards.

8mm is too big and does restrict some motion. I will probably not install them on the swash since you need the flexibility. Washers will be installed on blade grips/tail rod and a few places on the arm control....usually the most prone to pop off. For a long time, I have not had any issues. The reason is that I do not fly hard until recently my flying skills are improving. It makes sense to see things that normally would not be a problem due to lack of pushing the model to stress limits. Doing sloppy tic tocs are hard on the joints/fasteners.

Why don't we see the "pro" pilots that push their helis BEYOND their limits go the extra step ?? Just sayin........

Of course man! My first mistake was trusting the carbon pushrod. I should have removed it and used the stock wire drive. Pretty sure we would not be talking about this today.

The most important thing in the setup is to make sure there is NO binding on any of your control throws.......The rest takes care of itself ..
