I keep my SP fully assembled as all the locals do around here and carry it on a rear platform. I was tired of removing the four license plate screws off my car to reattach the plate on the carrier and reverse the procedure after coming back home each time I went flying. The NY State law says that the plate must be fully visible at all timer and have a light illuminating it. It seldom happens for anyone to get a ticket for not complying with the law but I didn’t want to take a chance and made a custom SP140 rack. For the last two seasons I have been using a powered screwdriver too move the plate back and forth and finally had enough of it as I was flying more and more with the SP.
I came up with a solution which works quit well and all the needed hardware can be purchased on Amazon to be adapted to the carrier.
I bought four plate magnets and a rubberized plate frame:
The plate support is a OXO vegetable cutting board😆
The light is a USB bicycle rechargeable light good for ten to eleven hours. I just need to remember to turn it on before night driving.
