No it was not canister ready. Just a sandwich shell, which was cramped full of equipment by the builders (not me).
I just made the engine, muffler system and prop extensions, so it would all fit inside. Only thing visible for the initiated was the spark plug cap just a tad in front of the carb air intake.
The pictures that I found will show a bit more, of how the smoke was ducted from the canister stinger to the scale exhaust, how the canister proper was inside the fuselage, etc.
