No, you cannot limit a FR (also called a BFR). Your choice is to either
sign it or not sign it. I may be behind on this but I do not believe
there will be any pilot's certificate issued for SP-single seat. In
other words, a BFR can be given in any aircraft the pilots is rated in.
I would assume a SP could receive a BFR in a J-3 cub. There are still
lots of Q's out there though.
