VQ models offers a 75" Cessna 188 in two different colors, red, and yellow/blue. You can find them at
www.vqwarbirds.com. I have the Yellow/blue version and is is a nice flyer. Strangely my wingspan measures closer to 78" not the 75" stated spec. Several others offer Piper Pawnees in 80" to 110" winspans. Hanger 9 (horizon hobby) has an 80" Pawnee and Texas RC Planes has a 110" Pawnee but no Cessna 188 at this time.
