Simitri F3J Information The Simitri F3J is the newest addition from the maker of the Euphoria. They had honed their skills on the Euphoria, making it one of the best flying models and values out there! Simitri is a step above the quality of many of the models we have seen. The fit and finish are A quality, and the execution of carbon line spread tow, and the composite is top shelf. The wing is carbon line fabric, with a new spar technology that is very strong, and very lite. The polyhedral wing circles excellent with the trilerons, launches well and will hang with the best of the best! The wing linkage has LDS installed, ready to install servos of your choice, we like the MKS 6110's and 6130s in the flaps. The Rohacell CNC tails are flawless and very light. They can be removed for transport, and with the 3pc wing, this model is great for breaking down well. The fuse pod is kevlar 2.4 friendly too Features

Pike Prestige

First of all thanks to Philip Kolb for constructing an exceptional model in the F5J world. He was not influenced by various fads in the F5J world and used all his knowledge, experience and best available software to construct the amazing PRESTIGE 2PK.To this we added the full rohacell core to the design, the whole model is made in heated aluminum molds to a very high temperature. This technology creates a light, strong and stable platform for years of flying.It is worth mentioning a few properties we have found very nice after flying this model for a while.

In circling the model as expected did not have a need for extreme dihedral joiners since the aerodynamic design and airfoil changes does that work in a better way than increasing dihedral. It was first produced with 6 degree tip joiners and then we added an 8 degree alternative. It has also been flown a lot with 5 degree joiners with good success in low altitude thermalling at EC F3J 2019. There should be no need for extreme joiners though this is again a personal preference. Circling camber can be extreme (5-8 degrees) while still maintaining speed during because of a new tail design that keeps the energy better (less drag). This means high bank angle is possible and yet still keep the high lift in a tight thermal.The large and newly designed rudder makes it possible to yank the model into any thermal you find.

As you will find described in the designer Philip Kolb’s writeup the penetration in all camber settings is very good because of the new tail design. Now you can change camber at any point without losing flying energy like we see in many airfoils. The model now just speeds up to the desired speed/camber setting and keeps that for a trip over the whole airfield thru lift and sink. Night and early morning testing have shown sink values as good as 0,35-0,4m/s in distance mode (1mm up along the whole trailing edge and measured by altimeter). That means search mode for thermals is very efficient and a fantastic glide ratio. Flying in full camber in the same conditions gives values in the range of 0,25-0,3m/s but less area is covered.

Landing the Prestige 2PK is easier than ever. No aileron setup is needed (aileron goes to neutral when brakes applied). Only flaps and elevator compensation. Still the model slows down to a crawl and pushing over is easy as the new elevator keeps the energy well even with full flaps applied. The rudder is also better and bigger and with the new high dihedral middle and aerodynamic airfoil changes it corresponds well to rudder input and is not as much affected by sidewind as earlier models. Though it should be said that the lightest layup has very light tips and heavier tips (inertia) might be preferred if the landing area have lots of sidewind and/or turbulence.The nose is removable. It is made longer than needed and can be shortened ( max. 100 mm) according to engine weight and lipo. Install equipment and shorten nose to fit preferred CG. The original nose has a diameter of 32 mm. It is designed to fit cheap and reliable outrunners for lighter versions. Very soon we will produce a nose cone with slimmer diameter of 30 mm.The servos and receiver are located in the fuselage under the center wing therefore there is enough space in the front for the motor, controller and lipo. Battery size from very small and up to 2300mah can be used as much care is taken to a very thin but almost square fuse in the front area.

The complete wire harness is built into the center panel and the central connector is ready installed. Wire harness for fuselage is also delivered ready made.Servo compartments in wing are laminated on all sides with carbon fabric, so a very strong box has been created in which the IDS system can be mounted. We recommend to install IDS for KST X10 mini, JRDS 181 or 189 for flaps and MKS 6110HV in the tips. For fuselage are suitable servos size like MKS 6110 HVIn the future will also produce a V tail version Although it is a new model a few pilots had it before WCH F5J 2019 and only had the chance to test for a short time.So in the biggest F5J competitions of all times the pre contest 4th WCH World F5J Challenge only 3 pilots flew with the Prestige 2 PK. All 3 was pilots were in Flyoff out of 190 pilots. Robert Bonafede won the 4th World Challenge and finished 3rd at the World Championship that followed.Other pilots with the Prestige 2PK achieved a lot of podium positions in a lot of other F5J competitions. We wish everyone who purchases Prestige 2PK many great experiences and sporting successes.

Euphoria F3J

The Euphoria is a magnificent full-carbon thermal glider that features the latest advances in aerodynamic design. It builds upon the strengths of successful gliders to create a model where pilots can grow their skills in F3J and Thermal Soaring class competition. The moulds for the wings and tail surfaces have been created using CNC milling machines to ensure superb accuracy. Furthermore, the four-piece wing section is carbon-skinned for additional strength and stiffness. This four-piece construction allows for larger ailerons to give you great roll control. All the wing control surfaces are large, making camber changes effective. Additionally, the large flaps allow the glider to be spot-landed very slowly and precisely.

This wing design allows for great turn ability and landing control. You will also notice the excellent glide angle and low sink speed. The Euphoria's wing, in addition to its tailplane, are made of spread carbon construction, making the model durable and light. This wing has a large spar, allowing you to perform great aerobatics and strong launches if you so desire. In keeping with current trends, the tailplane has been mounted on a small pylon in front of the fin. The tailplane comes with a separate elevator to give it precise pitch control. The carbon fin features a large film-covered rudder to reduce tail weight.

The pod is made from Kevlar and features a precise snap lock canopy, under which you can easily accommodate a 2.4GHz radio system. This pod is solid, yet lightweight and comes with a carbon fibre tube as a tail boom. The rudder and elevator are also lightweight and are made from CFRP shells. The servo bays can accommodate servos up to 16mm in width for the ailerons. The Euphoria also comes with a ballast tube, allowing you to adjust the weight for windy conditions. The Euphoria has a brilliant finish, with all fittings, locks and joiners coming pre-assembled. All parts slide into place perfectly. The Euphoria comes with pushrods, control horns and linkages. You will need to glue the tailboom to the pod (a jig is provided). Other necessary small parts are included.

The Euphoria is an outstanding competition glider that will deliver championship performance.

Egida F3J

The EGIDA is the latest design from Jaro Muller. He designed the EGIDA to incorporate the successes of his past designs, while developing a model to take advantage of the latest material enhancements. Jaro successfully made the EGIDA 63 ounces full strength with better handling than the RL, a better hang rate than the competition, and legs and L/D like the Satori. In our opinion the EGIDA is Jaro's greatest design to date.The EGIDA handling is much improved over the RL, the EGIDA is very easy to fly and while in a turn it required very little rudder, and can completely be flown with the right stick. This is because of the extra dihedral built into the tips. This creates a very user friendly model, and allows you to focus on the air more than flying the plane. The aileron area is also increased and they are extended all to the tip allowing for a less drag in a turn and increased roll rate. The most surprising part of the design was the effectiveness of the V-tail. Jaro put a very large V-tail on the EGIDA.and in the past V-tails where undersized and had some nasty characteristics like snapping and bad landing control. We were pleased to find that the EGIDA did not have any of the bad habits. The V-tail actually had more landing control at slow speeds than the X-tail Espada RL with big stabs. Also during tests we tried to snap the model and giving the model full up in a turn did not snap it, and also full up and full rudder did not snap the model. The EGIDA is a very stable platform, it grooves and locks into a thermal turn very well. The flap size was also increased compared to the RL. This allows for very slow landings and steep approaches. The big difference that we saw with the larger flaps was when a thermal came through on landing. In that condition the pilot needs to dive to stay at the same altitude, but with other models this greatly increases the approach speed.

Vixen F3J

The Vixen was designed by Daryl Perkins as a no compromise F3J model. Everything about the Vixen was well thought out for the task. It was designed to be easy to build light, and to keep the weight out of the extremities - note the V-Tail and two piece wing. There is no joiner box structure or joiner weight at half span which reduces weight out at the tips. The section choices are designed to have a wide speed range, pull hard on tow, and slow down well for a slow controlled approach. Many of you will question the six servo wing - it must be flown to be believed! The control surfaces are quite short, enabling the use of very small and light servos and less prone to twist or flutter. The largest benefits here are in the landing circle and the ability to slow down, controllably, and work the clock for that last 10th of a second. F3J contests are won on tow, and in the LZ. The Vixen is optimized for both." "The Vixen was designed by Daryl Perkins as a no compromise F3J model. Everything about the Vixen was well thought out for the task.

Pike Perfection F3j

Perfection in name and design, the Pike Perfection from Samba Model is a superb glider. This F3J RC glider is built upon the foundation of Sama's Perfect and Perfect ET gliders, with the new platform giving you better penetration and tighter circles. The Pike Perfection has a new tail to give you extreme power in the elevator, with even harder pings off launch and precise turnovers to hit those vital landing points. The lower-positioned nose helps in the landings. The new shape and airfoils of the tail, combined with a better cross section of the fuse, gives you better strength, lower drag and better penetration. Thanks to the new platform, the fuses and wings are lighter and the new materials in the skin ensure that the weight comes down and centres in the model. This gives you improved circling; especially at low speeds. Together with ailerons at the end of the tip, Samba Model have created a more agile model.The moulds are completely new and Samba Model have used new building techniques that were not possible with their older moulds. This ensures that the Pike Perfection is not only lighter and stronger, but also has a better finish. The stiffness and resistance of its parts are stronger, thanks to the new materials and high-pressure production technology. Full carbon material is used in the wing, fuselage, rudder and elevator. This is consistent across all versions of the Pike Perfection.

Maxa 3.5

Maxa is a combination of ultra-modern aerodynamic design by Joe Wurts and optimal structure from Vladimir’s Model. The design satisfied four main goals. The soaring duration was increased by new aerodynamic solutions from Joe Wurts and reduced weight of the new structure from Vladimir’s Model. The landing accuracy is improved by reducing the plane inertia, increasing the efficiency of the control surfaces at very low landing speeds, and the shape of the pod, which stops the plane as soon as the nose touches the ground. High speed dynamic launches are greatly improved due to low drag of the wing and other part of the plane as well as by the increased stiffness, which is especially important at high speeds of the launch. Penetration, the ability of the glider to return from distant thermals without loosing much altitude, is improved by the exceptional aerodynamic properties of the new model.Maxa 3.5 is the universal soaring leader for any weather.This glider takes advantage of even the weakest morning thermals, thanks to its light weight. High structural stiffness and novel aerodynamics allow ???? 3.5 to easily climb and return from distant thermals even in the windy weather.Efficient wing mechanization permits accurate control of the flight speed not only on landing, but also during the search for thermals.Increased area of the light horizontal stabilizer improves the control and guarantees “bull eye” landings.

Espada RLX

The Espada RLX is a new model that I mentioned in RCMN as having what looked to be an exceptional design for F3J and as a light weather competition model. Watching this model perform at Jerilderie it showed exceptional performance, it launched well, thermalled superbly and has a very light weight for it size. The models wingspan is 3700mm it has a length of 1615 mm and the f3J version weighs 1950gm complete. The wing section used is the HN785JM and it has a wing area of 70,1 dm2, the elevator section is a symmetrical 9% section and the elevator area is 6,0 dm2, construction of the model is fully molded. In the last F3J world championships a junior U.S competitor achieved second place with this model. Overall this model is an excellent model for F3J and is way strong enough to take punishing launches up to 15 knots. I recommend to change to the smaller model in higher wind speeds. This model is a fine performer and if you are interested in an outstanding f3j/ light weather thermal model you will not be disappointed with the Espada RLX and this model combined with the smaller Espada make a formidable team. An Australian team member will be using this model in the next F3J World Championships.
