If it is the tail dragger, the speed brake is under the tank , whereas I
think that Austins is under the main gear if it is like Farrys. It opens at
the front as well, like a big airscoop.
It would be interesting to note if any of the other Tri Q guys have one, and
how much difference it actually makes. Could be I need to do it after all,
if anyone has the plan for that version.
