I have just completed a one year process with the FAA to get a waiver to the regulations against charging for the use of an experimental aircraft. Many thanks to the LOBO members who helped make this happen.
The LODA I have permits charging for flight training (in particular the LOBO training) in my IV-P. It specifically prohibits Demo flights. You can see the waiver at http://www.dragonnorth.com/lobo/N776CM_LODA.pdf
