J'ever notice that Malechek is a little fussy about his sliding canopy, Mr B. ? If someone is not careful and he gets a little racking, the sliders can come off track. To stop the racking one has to somehow connect both sides so they both move simultaneously and equally. I have seen a system of cables and pulleys on a Dragonfly that prevents an unequal distribution of force but I ain't got it figured out yet.
The 4 arm canopy that patillo has gets you the air blast but does not lay down close enough to the front deck when open. This may discourage one from having it open during taxi. I dunno. It probably racks a little but may be more stable than the sliders.
