The E-racer canard is 147" long, excluding tip extensions. IIRC, this was done to make the lifting surface outside the fuselage the same as the long-eze. The E-racer canard is also mounted lower on the fuselage, more in line with the strake.
The Cozy MKIV had an original length of 141", after flight testing this was changed to 135", also excluding tip extensions. The elevators were also shortened 3" per side. I will let others debate the relative effects these differences may make.
