Hi Steve,

1. The link below shows a picture of a good ball link set up. It is for the dark arts but you can see how it would work in CL. Central Hobbies is an excellent business to deal with. ...... But Jim at "Control Line Central" will make you a complete ball link, with CF pushrods, setup custom made for your CL plane. After you add up all the parts costs and a few $ for your time, you will see that Jim's custom made set ups are an excellent value and worth every penny.    ..... BTW: you can also order RTF lines from Jim at any length and size.

2. You can't go far wrong using what Garf uses. This is a great starting point for most classic size planes.

FWIW: I have noticed out here, watching the worlds top CLPA pilots, that long lines are favored. They use very powerful PA engines and very powerful electric motors. It makes sense to use the longest lines you can, "IF" you have the power for them. If your power plant has a lot in reserve and you can get the planes speed up enough to still keep your favorite lap times (4.9 to 5.2?) then you may want to try 62' to 64' lines. The max by the rules is around 67' eye to eye (70' center of handle to center of aircraft).

Line length will be determined largely by what power you have on the plane. Of course, if you use a Zinger propeller, you'll need lines about 2' shorter than some other props. Honestly, I don't think there is any combination of engine/airplane that will be better with a Zinger than something else.    Steve

Hi Steve H.,

Steve, you have to start calling them by their correct name  ...... they are not props, they are called "prop kits".   

Actually the zinger pros are not too bad, but like you said; for CLPA there are much better options. ;-)

I hope to see you at the GS champs again this year, if they set a date and place?

Warm Regards,

I used to use the Zinger 11-5. At the time I thought they worked pretty well. Then I went to Taipan, then to Cyclone.

Zinger's make great prop kits. Plenty of wood to carve on.

On mine, I even tap the holes to 4-40 so I don't have to drill them out.  Then the nut is just like double nutting.  Did I say that right? DOC Holliday
