You need to consider another engine for your cruzer. The carbureted Rotax 912 carbureted engine will make it terribly underpowered. Very difficult to synchronize the carburetors and keep them that way. Have a friend that has that engine in a 701. Does not like it and is always fiddling with it. Also very complex to install. Lots of hoses and connections
You need more power for the 750 cruzer. 130 hp will make it perform nicely.
Have you considered the Viking aircraft 130 engine (vikingaircraftengines.com). Produces excellent torque which translates to outstanding thrust. That is what I am putting in my cruzer.
If building in stages, start with the tail to get used to the process, then wings, and finally the fuselage.
i am working on 750 Cruzer purchased it all at once, but I think build order for storage and skills is rudder to learn, right wing, flapperons horizontal stabilizer and elevator, left wing, rear fuselage, front fuselage, join fueselage, gear, motor mount, motor panel, install tail, install wings, final bits and panel.
The order optimizes space since wings are earsier to store than the fuselage. The other issue is the wing can get monotonous. So doing the tail and control surfaces in between gives you a break. To optimize purchasing, you might do the wings together. Just my 2 cents worth . Some people like to get the fuselage done first to work on engine and panel in between working on wing, since there are lots of planning and wall time waiting for stuff, but you need the space to build that much at once.
