"HELP" Getting "Re"-Started
The gyro I like for a decent price is the GY 240 by Futaba. For best results you would need the GY-401 + Servo S9253 combo.
703 are you referring to the HH gyro by Telebee? If so it is basically a kick off of a CSM HH gyro. Loci I believe is the trademark of Telebee Inc.
