Bio Engineer Archive

I am a CH and I am having a Bio-Engineer give me her grind Kaadu's so I can get XP. I was going to give them away for free to new players as mounts.I was trying to do this today and I was not able to train these Kaadu's as mounts. They were not made from Kaadu DNA but I don't know why I can't make them mounts. And yes, I do have management IV so I can train them as mounts. Any help is appreciated.

kaadus, wild or BioE, cannot be trained as mounts until they reach a certain growth level. I don't know what that level will be under the new system (it used to be CL7-10)
