It's funny, 2 years ago i bought a Turnigy G46 to replace an E-flite Power 46. I was thrilled with the performance and was convinced at that time that these were the same motors or a great copy. I now use the Turnigy motors in any of my new airplanes or replacement in old ones. I've done the same thing with the Zippy batteries over the E-flite batteries. The discharge rate of the zippy's are very good and I prefer them over E-flite.
