Ball for 700n throttle

[chopperleroy]

i seemed to have lost my ball that goes on the engine arm, are they a standard size like the ones that are on the head parts?

thanks

Yes they are.

Align balls are all the same size, and different from most other makes of heli!

I think Align balls are 5mm dia and other makes (JR, Hirobo, Xcell, TT etc) are an imperial size and come in at about 4.7mm or something.

So don't use a non-Align ball with an Align ball link - it will be loose.
