Hi, all, long time listener, first time poster.

I'm planning on flying in the Region 10 contest in August in my club's
mighty Grob 102CS. *I know this will strike fear into the hearts of
all the other competitors.

Unfortunately, we lack any tow-out gear.

I'm in the process of building a wing wheel, and I have an idea on how
to build a tow bar, but before I go with my idea I thought I'd see if
anyone has any pics/drawings/ideas on how to build one.

Anyone care to post a known-good solution?

I'm assuming you're focused on the towout bar, which is what is unique
to the Astir CS with its unconventional tail dolly.

For my ship, I did the following:

- Extended the wheel axle using a longer shoulder bolt and
appropriate bushings.
- Had my welder fabricate a tow bar that ran under the tail skid and
then attached to a "c"-shaped section of flat stock.
- Two notches in the ends of the "c" legs picked up the bushings
- Secured with a small bungy on either side that cliped onto the tail
dolly wheel forks.

It would be a lot easier to see in pictures, but I sold that ship
nearly 20 years ago and don't have any pictures of the tow bar.
