Muzz,
The canopy comes with a kind-of sequencing valve. I guess if operated by a slowed servo, it should work without an extra sequencer.
The gear is another question. In fact, on the main gear, first the two doors on the wheel need to open, and then the smaller door over the strut. Otherwise, the doors will hit. I have an EVU5 for that, with an extra EVU2..
