Ball Links

[rpd617]

Question about ball links, are there different sizes of these?
If there are how do you determine the size you have?
I have a Knight 50 sport and would like to get some extra links. Should I just order the ones that are listed in the parts list for this heli, or are there generic ones available.
Another question about tail blades, how tight should they be. Flopping around or tighter, more like the main blades?

Thanks
Rick

I run 'em looser than the main blades. If you tighten them down too much, you can put a lot of strain on the tail rotor drive mechanism (be it belt or torque tube), shortening its life. With them looser, the blades will give before the tail rotor drive will.
