Ok, I've been trained for 3ds max and gmax in college.  But this is something totally new thats gone wrong.  Since im still pretty new to designing, maybe you all can help.  I am building a full sized Northstar (an R/C favorite of mine).  I have the basic plane done.  Im working on making the landing gear and its animations.  When i try to animate the gear, the tire warps into an oval and doesnt stay circular.  by the time I have the gear retracted it looks like i got an incredibly weird flat tire.  When i put the gear back down it returns to normal.  Any help, im stumped.

Thanks I'll give it a shot.
