RE: graupner commet twin edf
If the motors you have are Graupner PN 6330, the motor OD is 1.14", the length is 1.875" and the shaft is .125" and a Kv=2296.
A quick look at Hobby Lobby shows a Multiplex motor BL-400/4D, slightly smaller diameter, about the same length, same shaft diameter and a Kv=5200. These motors are about 2 oz lighter than the 480 and should be used only with a 2S LiPo battery.
Look around various web sites and you will find numerous other brands that will work just fine.
