I found when figuring a scale for nearly all Defiant Class models out there, in MPE a 1.00 scale, i call it 100 and multiply it by 1.9 and when i measured the Defiants i got a length of 143 meters, close enough, so iv been measuring my models using this method, and surprisingly most of the models have been coming in close to their canon lengths with a few here and there either long or short, IMO thats pretty good for a largly Fan made game, so Kudos to all you hardworkin Model makers out there 8)
