You might find plenty on this subject with a search. Short version, sliders mostly seem to want to just slide shut, tip-ups cause severe pitch down control problems. My wife had the canopy come open unexpectedly on our RV-6 tip-up and the airplane lunged for the ground. Her headset went overboard, hanging by the cord. She could not get it latched and landed holding it down, needing three hands and more strength. VERY dicey, highly, highly not recommended.
