I flew my tango today with the eflite 45 motor the plane is alot of fun to fly. I think a tt46 would fly one great this one guy i know has been flying his with tower hobbbies 46. Asforservosgo ahead and get the 3003 you dont need to spend a bundle on digitals. enjoy the plane. I was really surprised at how well the e flite 46 hauled it around or should i say the batteries that i bought cost a fortune but a 40 size epower is something i have wanted to do. So i wouldnt have go to the flying field after work this has been a fun experiment.
