Filip Slope

Wingspan: 60", Wing area: 376 sq. in., Weight: 21 oz., Wingloading: 9 oz./sq. ft., Airfoil: RG15, Skill levels: INT/INT, Radio: standard receiver, 3-4 micro servos, 600 mah battery, Wind/Lift: L2-S2

New! T-tail now available!

This nicely made slope sailplane is perfect for the intermediate pilot but any expert will enjoy its handling and performance. What's even better is that the Filip Slope is an ARF! For the slope flier who doesn't want to build and wants to have the best in a versatile slope ship, the Filip Slope, this is the way to go!

The Filip has a painted (gel-coated) fiberglass fuselage with contrasting canopy. The wings are foam then reinforced with fiberglass, sheeted with balsa and covered with oracover. The wing is completely finished and is ready for servo installation. The ailerons are precut and beveled and servo bays are cut with the wire holes ready. The wing is finished in in oracover so very little is left to the modeler. The wing is beautifully built and light in weight, utilizing the RG15 airfoil modified at the tip for optimum performance. The prebuilt V-tails are covered with matching oracover and the elevators are also finished and covered ready for hinging. Just glue together the two V-tail halves and you are ready to go. All you do to complete the kit is to hinge the wing and tails,mount them to the fuselage and set up and install the radio system. This is a very high quality sailplane and a very well behaved flier.
The people at NSP make sure you get a complete set of hardware as well as a set of illustrated instructions. One of the great features of the Filip Slope is the two piece wing. The wings come with a wingrod so that you are able to set the Filip up so that the wing can be broken-down for storage and transportation. All hardware is provided to do this with and small amount of modifications is easily accomplished.
The V-tail is mounted on the tail in a molded saddle on the fuselage and can also be made removable.

The airfoil used on the Filip Slope is the RG15. It provides an increased speed range and excellent handling. Using three servos (two in the wing) gives the Filip Slope more precise, crisp aileron control, the ability to use the ailerons as spoilerons, and leaves room under the wing saddle for ballast. You can also use 4 servos, two for the ailerons and two for the ruddervators. With active ruddervators the pilot will have more precis control in lighter lift for inland slope soaring and thermalling. There is plenty of room in the fuselage to run the two ruddervator servos side by side so the ballast compartment can still be utilized.

Beauty, performance, and versatility make this a must-have plane for the slope enthusiast. This is a clean sailplane and will fly in an amazing variety of slopes and conditions. The light overall weight and low wingloading means that you are able to fly the Filip in conditions were many slope sailplanes are sitting on the ground. Due to the clean design of the Filip Slope, ballast the Filip up and it becomes a slope rocket able to do some amazing maneuvers and will fly in strong winds with ease. This glider is designed for a wide range of flying conditions. It is very easy for the intermediate to fly, and will delight you with its smooth flying and handling characteristics.

La Sierra Slope Soarers - LS1 Sloper

The LS1 Club plane was Designed back in the late 1990s by: Carl Maas,
Dale Winder and Mike Reed of Riverside California. These three gentleman got together and came up with a design that would best suit the clubs flying site. This Slope design was made a specially for the condition at the Riverside California LSSS slopes. Plans were drafted and planes were tested before they brought there final finished product to the club.
Plans were available for club members but kits were never made of this fine aircraft.
I purchase the plans and started scratch building the two planes myself. It took me about a month to complete both plane before they were ready to take to the slope. I couldn't believe how well they handled and the response I got from them. I was pleased with the plane. There were a few modifications that I did to the plans later on but I only make the plane stronger for the hard landing at our hill.
Both planes flow really well with a few trims to the controls in the air.
Later down the road, I purchased two foam wing from Carver Honn who was making them for the club at this time. The wing airfoil was a SD6060 and It flow even better then the built up SD6060 air foil did.
Carver then started to make Glass fuselages for the plane and they worked out pretty well. A few years later I started loosing planes right and left to the hill and then they all were gone. I soon moved on to making faster aircraft, but still had the love for the LS1.
I recently decided to do another scratch built models of the LS1 for new up coming members to see. Most of the older members that are still apart of the club today remember this plane and remember there first scratch built LS1 sloper.
The one that is on the LSSS site flies just as good as the first one I built way back in the 1991.
