Darren,

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.

Hi Darren,nice to see someone else in UK building Zenair,I have completed mine now,it is awaiting LAA permit to fly,I will let you know how I get on,my home airfeild is North Cotes in lincolnshire,if you ever get this way call in.

If you ever want a chat regarding any thing email is ...redleader51@live.com....bought your kit from metal seagulls yes,mine was from JLM aero.hope to hear from you,happy building.

Regarding the torque tube ie the thing that he Y bar fits to,it should be easy to turn this is elation to the nylon bushes it goes through,make sure he front one is aligned and there is free movement rotational b4 you rivit,never had problem with mine,it shouldn't be stiff ok bye Tony

Darren..I will certainly let you know the final weight  for my Cruzer once all is finished. I'm hoping for around 780 ponds or close to that figure. How has the performance been with your craft using the 912 engine?
