| DX7, Rex SE, HS65's, 401/9650, Align 35 esc and 430 motor.
My first radio, an AM MRC fully prportional in 1974(glitchmaster), then FM, FM dual conversion, PCM, PCM 1024 etc...
I must say I've had fewer glitches and hits with my Spektrum than any other.
My Rex always had an annoying twitch in hover, it was small, the tail would wag and the motor would hesitate. Of coarse it had too be the DX7?
I tried to address this glitch, I called Horizon - no known issue. I replaced the motor thinking RF - no go.
Recently after another sucessful flight I picked up my Rex and turned it over to disconnect the battery, the rotor spooled up to about hover RPM!
I looked at the Spektrum recievers and both were lit but I had no cyclic or motor control.
I turned off the transmitter thinking it would go into failsafe and stop the motor. Both lights on the recievers went out but the rotors kept spinning. I turned the transmitter back on, about one second later the reciever lights came on and I regained full control.
Not thinking too kindly of the DX7 I replaced it with a Berg 7p and Hitec Specktrum Tx, a combo I always had good luck with.
The glitching got worse! Frustrated I connected a tether cable tapped into the bec from the Align esc and hovered. What I saw was a distinct voltage drop which coincided with the glitch. Maybe the 401, digital servo, HS65's were too much for the esc/bec?
I replaced the Align esc with a CC35, end of all my problems. |
