I believe that Tom Morris sells/sold a nice looking copy of Brett's

John,

Yea, I've been making those out of PC board and putting in a bronze bearing. Works pretty well, too.

I think 'thimble' is the best choice, although 'bushing' may do.

They look like hard gizmos to machine -- if someone had the wherewithal to mold them out of nylon or something it'd make production faster.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

     I bought one from CLC and was a little disappointed.  They are not like the original by Brett but made for the "up" line in back.  If that's your preference, then OK.  The other things different for me was that the leadouts were .036" dia and crimped not wrapped.  I use .028" dia.  The hole in the bushing was off center, and the bushing in my opinion was too short.  This is not to say they are totally no good, just not what I expected.
     I made one (actually more than one) the way I wanted, with the "up" line in front.  I looks pretty much like Brett's.  It is not difficult, Brett posted some specific instructions somewhere, SSW I think.  The thimbles are easy to make.  They are made of .125 Phenolic plate (PC board) and shouldn't take more than ten minutes for both.  Cut them out on a scroll saw, sand smooth, and form a groove with a Dremel tool.  The Aluminum plate is .025" and available at most hardware stores and hobby shops.  This also can be cut with a scroll saw.  I made the bushing from .250 dia. brass.

    I cut them out with a jigsaw, then cut the groove with a Zona saw and then widen it out with needle files. That's not the hard part. The hard part is the bushing. Trivial with a lathe, not so trivial with hand tools.

I cut them out with a scroll saw and used a ball end keycutter mill to cut the groove using a jig. Worked pretty well. I bought the bushing from Lowe's. It's a .250" diameter bronze unit with a lip and an inset. I used a piece of .250" bronze tubing for the post. Works extremely well.

I should also say that while mine is similar to Brett's unit, the bellcrank itself is molded out of carbon fiber rather than the aluminum sandwich Brett uses.
