Is This Normal
Remove this ad - become a site supporter!
I have a Thunder Tiger OBL40 Trainer. When I turn the plane on without the transmittor I notice all the servors are fluttering as in everything is moving. With the transmittor on this goes away. If the transmittor is turned off then it starts to flutter again ( non stop ).
Any suggestions on what is going on?

Re: Is This Normal
You should ALWAYS folow this procedure...
1) STARTUP = Turn Tx ON First then Airplane.
2) SHUTDOWN = Turn OFF airplane the Tx.
Without the Tx on the Rx is just picking up stray electronic signals and it doesn't know what to doso that is why you get jitter.

For PPM radios this is normal. PCM radios will stay in position or move to failsafe positions (if you set them) with no signal.
As scaleguy said always switch transmitter on first, off last.

The PCM failsafe positions are set and stored in the transmitter. If you turn on the PCM Rx without the Tx, servos will hold position, regardless of the failsafe position.
In normal operation, turn on Tx then Rx and within a minute or two, the failsafe settings are sent to the Rx. Turn off the transmitter or loose the signal after this, and the servos will go to the failsafe.
