It's not podbot mm making default model. Go to AMX X forum and try to take a look at
Zombie Plague or
Zombie Biohazard mods (their sma code). They are changing model of players and that works very well. I think after 1 week we (ChickenMod Team) will release the new ChickenMod Orange Edition and You will be also able to see how to correctly modelling the player (new modeling of old ChickenMod)..
