A heavy storm on March 10th 2019 caused parts of the under construction roller coaster to collapse.
The 62.8m height statistic comes from First Drop, the magazine of the European Coaster Club and their source was an Alan Schilke interview conducted at the 2018 IAAPA trade show in Orlando. Energylandia has stated the height at 61m, 63m and 63.8m and even: "Zadra is the biggest WOODEN ROLLER COASTER in the world." Due to the ambiguity cause by so many statistics along with the misleading "wooden coaster" claim, the 62.8m interview statistic is being considered the most reliable.
The Zadra is the first RMC IBox tracked roller coaster built from the ground up versus a rebuild of a former wooden roller coaster.
