I'm using the Align 35A ESC model number RCE-BL35G. I guess I'm not 100% sure it's only the throttle but the heli never tries to spin or angle in any direction during the glitch. It just acts as if someone flicks an on/off switch for a split second. But maybe you are correct that everything is cutting out for a split second. I checked and my belt is not too tight, no servo binding, and the pinion is meshed ok. It's just so weird that the glitch happens more when the heli is right over me. It really never happens otherwise. So I'm guessing that maybe it's just some anomaly with the TX and RX when the heli is right over head.
