Think about it......We all have many helis, some of which are in excess of £1500-£2000 ($2000+), which are all (i hope) powered by main rotor head which has cyclic controls. These cyclic controls (and any other control) is all based around tiny little plastic ball links which we rely on to transmit an input to a rotor head which is running at over 1800rpm. Hmmmm.........if one little ball link went wrong, JUST ONE, then there is a good chance your f*cked (especially be it a cyclic ball link).
So my question is....have any one of you ever had a crash due to a plastic ball link come lose/crack??? I have never, but it does worry me a bit.

Plastic ball link ends do wear so they are an essential part to be checked during routine maintenance.I check my helis over after every single flight now and more thoroughly before the next day of flying.I apply gentle pressure with my finger to try to pop a ball end off the ball,if it does not come off then chances are it wont during THAT flight,if they are loose enough to come off CHANGE THEM..Also they are very prone to splitting on the outer end after a crash but if checked this will be spotted.Perfectly servicable ball links as a rule will not fail during a normal flight..

I have always been amazed that these things stay connected, I know the forces on them do not act in a direction to pull them off,but I still find it worries me if I think about it.

I've had the carbon tail rod drop off once or twice but never had a head ball link come off.

The modern plastic ball link is much better than the old type
which was plastic also but had a brass insert with a captured
hollow ball which would wear

Never had one fail, yet..
No failure, yet, after many years.. I did have the entire link from the upper mixing arm to the grip come off in a really hard auto..
I then spooled back up and flew around, trying to figure out why it was vibrating so bad.. DUH!!
I was amazed that the thing could actually fly with just one blade lifting and the other feathered.. So, you can lose at least one link and keep going, sort of..

I had one fail in flight once. It was on the pitch arm. As I watched the heli, I could see one blade flapping way out of track with the other one. I hit hold, and auto'd down right into tall corn. Little damage, but it pissed me off because the heli was fairly new. After that, I went to all "Rocket City" ball links. Still, the possibility of a link popping off or failing always is a concern.

Deadstick: Two of these can be found on a transmitter that has been inproperly charged.

Had one pop off a nexus
blade grip one time.Saved it though, heli acted as if it lost power and just fell from the sky,pulled off my first sliding auto 2 weeks into flying.I found too that not using a set of ball link pliars tends to weaken the links as well.Definently an item to pay close attention to during pre-flight.

Good Luck Corey I PAY-PAL
