48" Crazy Horse DS Sloper

The 48" Crazy Horse is an EPP laminated speed wing designed for a wide variaty of slope conditions. Flying weight is about 26 ounces as shown including radio and battery with about 10 ounces per foot wing loading. At this weight the Crazy Horse can fly in light winds and is aerobatic. We have also flown it at over 40 ounces and it still flies great. It is designed to be used high wind and dynamic soaring conditions but it still does well as a slope plane at slower speeds.
Dynamic soaring planes or DS designed planes can be built heavier that ordinary slope planes. The first time I launched a ballasted DS plane I was sure it would go to the bottom of the mountian, but it didn't. It flew surprisingly well and surprisingly fast. These aren't planes designed to hover but they are planes that want to keep moving. I have seen A Crazy Horse ballasted up to 40+ ounces and it still flew well in 16-20 mph winds on the slope. The magic comes when the wind is 20-30+ mph and you can let her loose and tear holes in the sky. DS or dynamic soaring planes are designed for sloping speeds exceeding 100 mph in higher winds. Some are are flown way over the 100 mph depending on the type of slope, wind conditions and how the plane is balasted for the high speed penitration.
Ted came to me and asked if we could cut some EPP foam DS planes for high speed flying. Ted is one of the slope flyers who flys with me who also flys DS. We have a local mountain where they are flying DS planes less than an hour from where I live. He requested 48" and 60" DS slopers with straight leading edges and tapered wings with a solid EPP block fuselage.
The straight leading edge makes the straight spars possible without any wing joiners which is a possible fail point in high G maneuvers. The fiberglass spars are designed in a top and bottom I-beam style construction making the wing very stiff for its weight. The tapered wing looks sleek and fast in the air. We have had other flyers comment on how good the plane looks in the air and other flyers have given suggestions on the construction and design of the plane. The thin wing is designed for penitration. The entire plane is cut from EPP which makes it durable with a longer life.
I need to give some thanks and credit to Ted who has been instrumental in the design and testing our prototypes. He has spent a lot of hours building prototypes and offering help and suggestions. At this point we have 6 planes in testing and 4 of which are already flying. See the videos below.
The kit comes with 1 plane in the box for $90 including laminate and hardware You read correctly, The kit includes UV shielded clear laminate and is only $90!!! The kit includes EPP elevons but some flyers are upgrading to balsa or bass wood elevons for higher speeds. I just finished a larger 60" Geronimo using wood yardsticks for elevons because of their strength and straight grain. I cut and sanded them to a bevel and found them to be stronger than basla or bass wood.
The Crazy Horse kit has EPP foam wing cores, EPP elevons, laminate, Coroplast rudder, 6 fiberglass spars, horns and pushrods. The thin high speed airfoil is built with a top and bottom fiberglass spars in an I-beam construction technique. It is designed and built like our power combat planes so it can have hard landings in bushes or rocky slopes and survive. The kit comes with and EPP block of foam you can cut any way you want to make your fuselage. This gives you the options of a flat or rounded fuselage and a top or mid wing design.
Our laminate does not need a spray adhesive to get it to stick. It's unique adhesive is activated with a clothing or hobby iron at 180-220 F. Instructions on how to laminate the plane are highlighted in the build videos below.
You will need the radio and receiver of your choice, a 3--5 amp BEC, higher torque servos for higher speeds and a 1000 mah 2S battery for weight in the nose. Some flyers are using 4 AAA batteries in the nose without a BEC. I like a battery I can change out at the field so I don't ever get the the slope with a dead battery and can't fly. The straight wing moves the CG forward so I had to add an aditonal 8 ounces of weight to the nose of the fuselage to get the CG at 1" back from the leading edge of the wing. The added weight didn't seem to affect the way the plane flies. With a lipo battery I can fly for hours on a single charge since there is no motor running. See the build videos below. It took me about 10 hours to build and laminate the kit and install the radio and get it ready to fly.
I like to build, tape and laminate the plane before even starting to install the radio. We are using a modification of building techniques that have evolved after years of flying combat planes and slopers. I have flown slope for more than 35 years. I have designed dozens of flying wings and other planes to be flown on the slope. We also fly powered combat and have learned how to build a plane that can take serious abuse and keep on flying. The EPP flying wings are very tough planes. We have researched many products including our spars, E-tape and laminate that keep the weight down but add incredible strength and still quick to build.
Things to remember when you are trying to maximize lift flying on the slope: The airfoil works best if it is kept clean. Only the servo arms are above the top of the wing and all of the rest of the radio and battery are hidden in the wing or in the fuselage. We do not want any wires or batteries to disrupt the air over the top of the wing.
The battery is in the nose to balance the plane but even it is fit tightly in the plane to prevent the plane from crushing and also to protect the battery and radio. The plane isn't fiber-glassed but simply laminated with our unique clear UV shielded laminate that protects the foam and the fiber tape from sun rays. This laminate does not need a spray adhesive to get it to stick to EPP foam. Our laminate only comes as clear so we add color with colored box tape after the laminate is applied. The colored box tape is bright, lightweight, waterproof and easy to install.
