The fix is pretty simple (in the following order):

1) Talk to the gentleman you chatted with this morning and request a NEW plane (one that is checked trouble-free in the factory) to be mailed to you. Not another part or lever cap.

2) Tell the gentleman they can arrange to have the plane in your possession picked up by a courier.

The new plane should arrive BEFORE the pick-up of the return. If a new plane is not available for any reason, get a refund and then the LV or used plane route would be the next step.
