Hi all, I got a spektrum DX3S w/the s3300rt telemetry sensor. I got everything installed. The weird thing is the RPM sensor works when i lift up my Savage 25 and give it throttle. Only when it's on the ground and it's moving, the RPM goes DOWN to zero and doesn't read anymore. Even jus doin circles in front of me. And when i stop and leave it to idle, the RPM doesn't come up. I put the black dot on my silver faced flywheel.

Temp / batt all works great. Love this radio. Any thoughts ?
