SIG Manufacturing Inc.. balsa kit plans for the following.. 1/4 scale J-3 Cub both clipped and unclipped wing variants. PLEASE NOTE BELOW….. RC 47 consists of 3 original sheets, I have had these from new. RC 48 consists of 4 sheets that have been reproduced The only difference between them all is sheet 4 All sheets have rc47 or rc48 or both printed on them… So I’m going to let the whole lot go as one lot so the new owner can have the best of both worlds ..
