As far as I know there is no such animal. A Gruman or Schweizer looks like this, a'67 A model, the smallest type. PAX

There was a demonstration Ag Cat race at one of the Mojave races back in the 1970s that was great fun to watch.
And yes, this has been a great thread. A thread like this is a great deal of work to do right -- you're not done with the shoot when the event ends.
When the event ends, the fun is over and the work begins, for the working photographer...
Thank you for this, Grant.
