Add a second receptacle tube that allows the canopy to be locked in a partially-open position for taxi
Glass over the factory air vent scoops
Add a way to hold the canopy open, ideally so that it can't slam shut in the wind. Ideas:
Rod system, similar to a car hood prop.
Difficult to operate if it's behind the pilot, not sure where attach it at the front
Latch it on the right side rail when the canopy is closed?
Strong cord or cable plus a calibrated weak link
Construct the weak link out of fishing line with a known test weight, using as many lengths as necessary to achieve the desired breaking force, and cover with shrink tubing. (Test to ensure that it breaks at the design weight!)
Add an elastic cord to pull the cord/cable into the cockpit when closing the canopy
