NEW 300 HP WACO YMF 5-D Model
Climb in to the WACO YMF, and experience flying the way it was meant to be.
Relive the freedom and excitement of barnstorming days while flying in a new production, luxurious aircraft.
- More Horsepower. New Jacobs R755-A2 300 HP with a 1400 hour TBO. This engine features the new production aluminum case and a longer TBO
- JPI EDM 930-7 Engine instrumentation as standard provides an all in one engine monitoring solution.
- New Oil cooler design provides improved cooling
- New easy access Oil Filtration system allowing for 50 hour oil change interval (up from 25)
- New MT Taper Tip Propeller provides approximately %19 better climb and higher cruse speeds the C model Waco’s.
- Front cockpit brakes now standard
- Redesigned landing gear, featuring Parker Hannifin Seals and new precision ground pistons.
- New Trim system design (linkage system replaces older cable system). Now nearly ZERO maintenance and smoother operation.
- Standard LED landing and identification lights, new beacon
- Deluxe leather interior now standard
- New fully adjustable rudder pedals (accommodates larger range of pilot sizes). This new design features lineal rails for adjustment and maintain a constant brake pedal angle thought adjustment range.
- New circuit breaker panel location on lower left of cockpit provides for much better organization and a cleaner instrument panel.
- Improved seals and other enhancements lower front cockpit temperatures in summer and improve heat system performance in winter.
- New lightweight wheel pants and wheel pant fairings with Air fill access Door
- Redesigned one piece instrument panel with vibration isolators
- Simplified avionics packages featuring all Garmin Avionics

Chief test pilot Carl Dye reported dramatic performance improvements over the C model.
Carl’s thoughts, October 20, 2009
"The initial flight of our WACO YMF with the 300 Hp. Jacobs engine was accomplished today and although no official data has yet been developed, preliminary results were very favorable. The R755A2 engine and the new MT wooden fixed pitch propeller appear to be a perfect match. The MT prop is the same diameter as the previously used Sensenich at 92 in but with 8 inches less pitch, 60 in as opposed to 68 in for the Sensenich. With the engine having a higher rated horsepower at the same RPM, I was expecting this prop to not have enough pitch to hold the engine speed below the max allowable at full throttle level flight but was quite surprised to find that this was not the case. In fact during takeoff and climb the engine speed remained below 1950 RPM with full throttle and a climb speed of 75 IAS. This is comparable to the 275 HP version but the rate of climb was greater. In level flight at full throttle the RPM stabilized at 2200 and about 127 MPH IAS. This is 5 to 7 MPH better than the Sensenich equipped 275 version. When cruising flight was established at 2000 RPM, IAS was 112 MPH, again about 7 MPH higher than my experience with the B2 equipped YMFs. This excellent performance must be a result of a very efficient propeller blade design that seemingly combines the attributes of both a climb and cruise propeller and is able to take full advantage of the additional power available. At best power, fuel consumption will be about 16 GPH but will yield about 5 MPH higher IAS. At an economy power setting of 1900 to 1950 fuel burn will be about 15 GPH and will see about the same IAS as with the B2 version. Keep in mind this is preliminary data and the weeks ahead will allow us to produce real numbers."
