I think Victory Saber should be somewhere around 17" after tirelessly cross-referencing various charts. Star Saber and V-Leo should be around 13.5", and Saber should be just around 7". That would put them in the same scale as WFC Omega Supreme, ER Optimus, Siege Jetfire, and Titan Devastator. Only rough measurements though. Some issues make it hard to be definitive though. JG1 only really matches US G1 scale when it feels like it, and WFC figures don't always follow scale charts as well as they claim, especially relative sizes compared to Optimus, but Jetfire, Omega, and Devastator all seem to follow the scale charts relative to each other which gives a good baseline for the size of figure HasLab is probably going for. Also, in a weird twist, unlike every other Scramble City-Style combiner, Piranhacon actually appears to be the correct height.
