servo arm balls

[e92.M3]

I have all of my Oxy2s converted to the longer 3x6 mm linkage balls but i find changing the arms themselves after around 100-150 flights despite of CA glue since the ball's threads just become too loose from the holes. Question: anybody here have tried backing them up with nuts? Link where to buy them?

Thanks

Yep - I have nuts on mine, I can't remember whether they were M2 or M1.5 nuts I'm afraid, just from my stock...

Thanks for the response. Once i get home i'll check the size. I might need to rummage deep among my parts bin of yesteryear's micros. I'm afraid of what i might find (bad memories).

The L-shaped wrenches are impossible.

Finally got a driver, ordered on ebay as soon as I clicked to pay I realised it was a Chinese copy - ugh - of course it was crap and was too big for the balls... So today I just got the align one, its quite small but works really well - at least compared to the L shape allen wrenches...

Oxy 2 is awesome. I think i can do everything with what 2 drivers or is it 3? And a pair of needle nose pliers. And even those are not really needed.

I push a starter tap through the hole to be used. This ensures the ball screws in easy but will not be to loose.
