Which model unit do you have?
Is it the landing gear or the stabilizers?
No matter, it's a fuse blown in the positive line somewhere.
If it's landing gear, the fuse will be near the battery, and may be hidden in the wire loom.
If it's the stabilizers, the fuse will be somewhere between the battery and the stabilizer switch.
The remote receiver gets it's power from the battery in a different location than the manual rocker switches do, and that's why you can operate them with the remote and not with the rocker.
