I'm considering buying an E-LSA that has not flown in years and has been stored in an open hangar.

I would like some advice to help me decide on this purchase.

How difficult is it to re-register an expired N-Number? What costs can I expect?

Offhand, what specifically would you want to take a closer look at if you were considering a plane that has sat that long?

Assuming it was not prepped for storage, how well could on expect a 2 stroke Rotax to hold up after all of this time?

Last, can anyone recommend a good A&P with Rotax 2 Stroke experience near Atlanta, GA?
