I had the same issue but solved it by using ball link pliers. Every one I remove by hand breaks. But with the tool they don’t break and haven’t broken under any load. Same helicopter.
Never needed those but good luck if you get a roban and decide to use the provided rod ends. I understand why you mentioned using the pliers due to the way I pulled them off keep in mind the weight is enough to snap them in my case all my 3d helis have never had rod ends snap in this way.
BEAUTIFUL blackhawk. I would have to agree...pulling them of by hands puts additional stress on them. THE PLIERS do help and can help squeeze them. One old guy says if your bird goes down..it's pilot error...it's true. Are some ball links better...yes; however, if you get more ball links get ball link pliers. I OWN Roban 700 EC 655 and it never happened to me.
@@edwinthomas618 I understand the slight additional street when removing them at an angle. most people fly their scale birds super slow and I prefer a scale heli that can also handle some cyclic abuse in this case when I attempt to load them under heavy cyclic maneuvers they give out. I'd rather be safe and install some durable solid rod ends. But I agree removing them straight off at a straight angle with the pliers will not compromise the integrity,
@28EduardoSierra I do understand and your video can be served as a public announcement for Roban's ball links. I've been flying scale for a long time since 2004 (the big boys). The best ball links in my years are by JR Propo and Vario. BTW, when you get your pliers, you can place the ball links in the flat part of the pliers and squeeze the ball link...this will make the link have a tighter fit on the ball. Check out scalerchelis and join if you hadn't already
You can get them from zhobby contact them through Whatsapp at +86 135 6035 3519 and speak to Tracy she helps me out and ships out what I need Everytime.
The reason your breaking them is because your bending them which stresses them and using your hand, use ball link pliers to sanp them on and remove them, I am not a Roban fan boy but I have built several Roban helis and never have broken any Roban links, they do fit loosely I have to say that but never broke, your over stressing them by bending them and forcing one end to push against the ball.
Also you are using way to long of servo horns, that ball should only be 10mm or so out on the servo horn, no wonder your breaking ball links, its not a 3D heli, fly it scale buddy.
Then u actually u don't understand that shorter servo horns increase torque and that should not be an issue with breaking rod ends I fly this thing hard now I don't fly it scared of anything happening to it now check the video

Thanks for sharing--- I`m thinking about getting back in the R/C world
I would have roban pay for the replacement,because of those faulty ball links ends.
Did ya ever try to sand down those dogleg connectors? Not ao they fall off, but ... IDK if theyre brittle, they will break anyway I suppose
Never had an issue
My ball links for my Roban 800 (same head actually) cracked after the 2nd flight here in the tropics....
But I was lucky to spot the breakage before flight...
@@andysitton8696 yeah there's no argument that they are made much cheaper in comparison to what you see on 3d helicopters
Proper tool for the job bud, where are your ball link pliers?

@@edwinthomas618 as I mentioned in the video I'm removing them aggressively to demonstrate that they break

I've been looking for the 700 scale Roban Blackhawk to purchase. They're always out of stock.
You can get them from zhobby contact them through Whatsapp at +86 135 6035 3519 and speak to Tracy she helps me out and ships out what I need Everytime.
They are across the street from roban limited and are able to get pats and kits easy
Did you end up finding it in stock?
Can we get more videos on the tb70? I wanna get one but I need more persuasion
Ok video is posting
‘sick-lick’ is the way it’s pronounced. Great 👍 Video
Never use cheap plastic 😊😊😊 always use The aluminum one's or metal .
I just use align of now using Tron ball and links

Never had an issue with them
Whats the flight time on it?
@@kristhianandrey9238 about 8 - 10 min depending on set up of rpm
