This is an untested attempt to fix animation and other issues with the cliffracer.
To test please make a backup of the folder data\meshes\creatures\cliffracer and then delete it. Next copy the new files from here:
Cliffracer v0.00

Currently Cliffracers lack havok (will be added once animation issues are dealt with) ... this means that they will not die properly (will remain idle when killed).
If they work, the Cliffracers should fly at a fairly high altitude when unaware of any enemies and should slowly descend to a lower level when they detetct an enemy. When in combat they should fight and move at this lower altitude untill killed or untill they kill the opposition. If they win they should then slowly rise up to the higher altitude again.
I am also interested in knowing if there are any other animation issues still present with the cliffracers or if their altitude needs to be tweaked etc.
Note: Their Speed in the CS might need to be adjusted ... try copying the speed value of Oblivion Will-o-Wisps.

As far as I can remember, Cliffracers attacked you like any other creature ... they kept on wandering untill they detected you and on detection they immediately flew to attack you ... are you sure it wasn't a mod youre describing.
