You should do a search on this forum and the usenet (Rec.Aviation.Rotorcraft) on NOTAR's. You will find plenty of info on them, both the good, and plenty of the bad.
The only real difference of wind from the right (over the "E" model), other then the tail being bigger and catching more wind, is the increase demand of TOT/Torque over the tail rotor version. The NOTAR generally does not have a very big excess of TOT/Torque available.
Dang, and today I have to trade my "E" model in for a BlowTar so that I keep everyone happy that I am current in them. At least it is only for a day.....
