HI All,

Just wanting to hear experiences with using the Strega ARC BC and crimped lead outs as they come from the factory? I would rather not cut up a lot to change them out unless there is a failure rate to the stock ones.

Thanks!
Bill

Hi Bill,
I had an ARF Cardinal on which i left the original crimped lead outs and never had a problem on over 200 or so flights. I only hope they continue to hold out for the guy I sold it to

Cheers
Al

Big Bear, I thought you would know better. Yes you can slap my hans if you want. I would only use crimped lines/leadouts only as a last resort. I know the combat guys use them a lot, but how long do their planes last. All my ARF/ARC's had the crimping replaced. Used to wrap my lines/leadouts, but since Carl Schoupe put me onto the swagging method I may never go back. I can make a set of lines in a fourth the time it takes to wrap. I also do a pull test on them that the judges would fall over if they had to do it. Think in excess of 100 pound pull test.

Right on, Doc!

There are a lot of ways to spell the process - the one I learned about 50 years ago was "swaging" - the process of forming a softer outer metal so it conforms to material passing through it.

Carl's swaging pliers can produce a crimp that forces the aluminum or soft copper outer tube into the steel wires making up our usual 7-strand cable flying lines. NOTE: per AMA Rules, swaging ends for steel single-strand line is NOT allowed...

His package stresses developing a gradual, smooth crimp, evenly formed around the swaged section, and it takes a dozen or so gentle squeeezes, turning the section some in the pliers' jaws, to accomplish. Not only holds very well, but looks very neat and proper.

A "factory" crimp is usually only a few squeezes with round jaw needle-nose pliers. Carl's tool forms a much greater area, with more uniform result.

I lost a custom profile quite a few years ago when one leadout fatigued at the wrapped termination.

I can swage cable down to 1/16" (.0625) using the equiment at Home Depot. It's good for control handles. You just buy the cable & swages and use their tool in the store.

Where do you get swages for .018, .021, .024, and .027"

Of course you did, Phil.

I've been using nylon coated salt water fishing leader for cable leadouts. There are separate packages of tubes to swage or crimp for each size leader. Works fine for me.

Bellcrank removed with minimal surgery. Hopefully no further surgery to reinstall the BC.

I just couldn't bring myself to trust it on a .60 powered stunter............
