I slid my fingernail between the canopy edge and fuselage "rail." Pops right off. Did not even have to pull on the canopy. I've been adjusting/playing with the length of the brass pins so that the groove fits into locking pin. 'been moving it up/down in 1/8 turn increments. Can't find the sweet spot where it will lock in. It must have something to do with the latch mechanism attached to the white push-pin. Maybe it is getting stuck. Also, the pins that are about mid way down the length of the canopy are off as well. YIKES. I think my next move is to put some chapstick on the latch to try to lube it. If that doesn't work, I will buy some new latches from Mike.... Yeah... it's a reasonably priced airplane, but it's just these little things that drive me nuts....
