telebee gyro sux, align gyro sux, efliteG90 sux

get a GY401, logictech2100, CSM 420ME or better w/ S9650 or JR3400 servo

the DS285 servos (super accurate and digital) that come with the dx7 microlite used to be the best servos until the HS65MG came out. the HS65MG are almost invinsible servos and that's why i recommend them to a beginner. the DS285 are one of the most fragile servos out there and a minor crash will probably break them all at once. if youre referring to the DX6 stay clear. the DX6 sux for ECCPM and the S75 servos are weak and flimsy...they will make the trex so hard to fly therefore for beginner you gotta get the better stuff...see the trend?

the DN charger is okay, but limiting. look into a triton2, astroflight109, or Thunderpower1010. the astroflight is probably the best bang for the buck lithiumwise. triton2 is useful because it will charge all types of batteries, but won't cut it for anything more than 5s, 1010 is the Ultimate lithium charger but will cost a pretty penny

the mx400 on realflight g3 is supposed to be very close to a trex
if expertly setup, the trex can fly as nice as the dominion90.
