Big scale Golden Age biplane |  |
 WACO (Weaver Aircraft Company) of Loraine, Ohio was one of the premier aircraft manufacturers of the Golden Age. The YKS-6 was a large cabin biplane with seating for 4-5 people. Its large wing area and overall light weight allowed it take off and land in undeveloped areas common to the US in the 1930’s. Our model is of the airplane that is owned by the Deutsches Museum Flugwerft Schleißheim. This airplane was originally built as an ambulance aircraft in 1936 and spent the bulk of it service life on floats in the Alaska outback. Restored in 1989 the plane was later shipped to Germany and is still in flying condition with its original registration numbers. Hobby Lobby stocks spare parts for 1/4 Scale Waco.
Our airplane has a 100” wingspan and is 74” long with a 2496 sq. in. wing area (that’s over 17 sq. ft. of wing area). At 20-22 lbs. flying weight, it has a low wing loading typical of a Waco. We included lots of scale detail to bring the model to life: corrugated ailerons, working doors, scale aluminum wheel hubs, airfoiled aluminum wing struts, scale rib spacing and scale outline and colors.
All laser cut plywood construction, the airplane comes in 2 large boxes with a great deal of the tough work already done. The main parts are pre-assembled and covered with the graphics pre-applied. The wings are easily removed without disassembly; there is no rigging to deal with. Battery access is through the operable doors on both sides of the fuselage. Total build time is about 15-20 hours. Complete hardware package included.
Whether built as an electric or gas model the flight performance is a total joy, take offs are short and climb performance is quick. The airplane will slip into a small field just like the original full scale one did. Our recommended electrical setup provides much greater than scale performance, we rarely get above half throttle. Flight duration with a 5000mAh battery is well over 10 minutes with reserve. Airplane can be flown with 10 or 12 lipoly cells and balances with the batteries inside the fuselage.

History of the Orange and Silver WACO YKS-6 The YKS-6 on display at the German Air Museum was built as an ambulance aircraft in 1936. After its delivery it was in service in Alaska until 1989, primarily with Anchorage as its base. Up until 1969, it had floats instead of landing gear. In the inaccessible lake areas of Alaska, it served for the recovery of victims from accidents and for the transport of patients. In the back of the fuselage, one person can be accommodated on a stretcher.
The YKS-6 is appreciated by pilots as a reliable and stable plane and it has proved its excellent efficiency in the rough Alaskan climate with ice, snow and extreme cold. In 1989, a full restoration of the airplane was carried out. In April 1997, the restored plane was ferried from Las Vegas, Nevada, across the American continent to Stinnes International Airport in Mississippi by the pilots Walter Eichhorn and Marwig Herzog, in 18 flight hours. In Mississippi it was disassembled and shipped to Germany in a container. The plane on display is airworthy and still registered today with its original aircraft identification mark NC 16512.

This review maybe seem very late after this Airplanes debut, but after receiving my two huge boxes containing this awesome bipe well over a year ago, life events caused a bit of delay in my getting to and completing the build.
All I can say is WOW!! I love this plane. The build was straightforward, and I had no problem following the well written directions with color pictures. Within the last year, I have started in using gas engines for my aircraft that are 1/4 scale and bigger. I'm an electric flyer at heart, but for these bigger ships, I really like the gas engines for cost, flight times, and Doppler shift (sound). My WACO has a Zenoah Twin GT-80 on the business end, with a 60oz gas tank for 35 min flight times. The twin cylinder engine is so smooth, very little vibration to shake this gorgeous ship.
The maiden was one of the best I've ever had- very little trim needed, CG was perfect as advertised and I needed no additional weight with that monster engine up front. The plane looks great in the air and I enjoy slow pattern work with many touch n' goes each flight.
Thanks for a great model!!

My video shows how it flew on the first flight. All the subsequent flights were even better.
I especially like the plywood cradles for the wings to allow transport and storage without taking all the struts off every time.
The WACO gets lots of positive comments at the field and it earned me the membership in the WACO Brotherhood #168.

I finished building the 1/4 scale Waco YKS-6 last week and have flown it successfully twice. It has plenty of power with my setup. (170kv motor on 10s (2x5000mAh 5s packs in series) with an APC 21x13 wide electric prop. It flew great with no trimming required. It looks awesome in the air. Landings and take offs were great. I'm looking forward to many more flights with it. Here is some video of the first two flights.

I had a successful maiden flight of my 1/4 Scale Waco this past weekend. What a fantastic flyer. It flew with no trim changes at all. Recommended throws were all good, except I could use a bit less elevator throw, or more expo on the elevator. It's only noticeable at higher speeds. Plenty of power on 10s 5000mAh pack and a 170kv motor and an APC 21x13 wide electric prop. Pulls about 51 amps at WOT for just under 2000 watts. Here's a link to video of the maiden flight on YouTube.
