Description
Don't miss this extremely rare opportunity to own this beautiful dream-come-true open cockpit biplane. Finished in gorgeous head-turning blue and white, with real all leather interior, the near flawless and tasteful appearance of N45373 turns heads on the ground and flying overhead. You'll be the proud owner of the envy of your airport! With a true center locking tail wheel, the best balance of the entire F-series, and the widest landing gear available on any WACO (two feet wider than an YMF-5) this aircraft is a pleasure to fly both on and off the runway. N45373 comes from the original WACO factory in Troy Ohio and was completely remanufactured by Bipe Inc., Jerry Stadtmiller in 2023, from the bare frame on out, and has been lovingly and painstakingly maintained and ever since, always hangared, and comes with a new annual from just June this year and three brand new tires. N45373 is truly the Master of the Skies, flies like a Cadillac, and is a Beauty to Behold. An airplane truly to be proud to own and fly!
