Jeti Model Central Box 210

 

The Central Box is a switchboard designed for the complete management of servos in a model with an emphasis on safety. The Central Box 210 offers maximal unreduced power for each servo (servo outputs do not have overload protection). The Central Box can manage up to two batteries and fully supports the JETI EX telemetry system. Up to three receivers with serial (PPM, EX Bus, S.BUS, UDI) output can be connected to the Central Box 210. With JETI DC/DS transmitter, the full potential of the Central Box can be used, such as an easy way to configure the Central Box, EX telemetry, and very fast servo response.

 

> Features

  • Central Box 210 has unreduced power for each servo (without fuses)
  • Support of DITEX telemetry servos
  • Possibility to connect up to 3 receivers with serial interface
  • Built-in Expander function for up to 3 sensors
  • Input for magnetic switch or RC switch
  • 2x MPX battery input connectors
  • 100Hz mode of servo outputs (10ms period)
  • Supports EX telemetry (voltage, current, capacity, temperature measurement, …)

Seagull Models KA8B RC Glider, 3000mm ARF, Yellow White, SEA-137A

Seagull's Ka8B Glider is a beautiful rendition of the timeless piece of sailplane history. With its graceful 3 metre wingspan, optional speed brakes and fixed landing gear, this Ka8B is sure to be an exciting airplane for any sailplane enthusiast.

 

Features

  • Perfect for ridge slope soaring or towed to height looking for thermals
  • Efficient airbrakes
  • Designed as an intermediate to advance sports trainer flyer
  • High wing airplane which is easy to fly and quick to assemble
  • The airframe is conventionally built using balsa, plywood and veneer to make it stronger than the average ARF Glider
  • Releasable tow hook point
  • Detailed scale cockpit with ultra lightweight pilot included
  • The current popular colour scheme which makes the KA8B stand out and look timeless
  • Covered in genuine UltraCote

The K 8 was derived from the earlier Ka 6 design as a simple single-place sailplane with dive brakes using construction techniques similar to the Schleicher K 7, simplified for amateur construction from kits. Emphasis was on rugged construction, good climbing ability in thermals and good handling characteristics.

The Seagull Models KA8-B was designed with the sports trainer flyer in mind. It is a high-wing aeroplane that is easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood and veneer to make it stronger than the average ARTF, yet the design allows the aeroplane to be kept light. You will find that most of the work has been done for you already. The pushrods are pre-made to the correct lengths, the motor mount has been fitted and the hinges are pre-installed and pinned for security. Flying the KA8-B is simply a joy.

Features

  • Two piece wing
  • Functional Flaps
  • Made of highly durable EPO
  • Fold away high-efficiency propeller
  • Snap together assembly, no glue necessary

Product Information

 

True to the FMS spirit, no detail was overlooked in the design of the ASW-17. The FMS engineers made 4 expensive tooling adjustments just to micro-adjust the airfoil for perfect efficiency. The wing, vertical and horizontal stabilizers are designed with a snap-together structure. With a simple snap, the surfaces attach to the fuselage with pinpoint precision- no screws or glue necessary! Build the aircraft in as little as 3 minutes! Like the 3000mm Fox, the ASW-17 has a pre-installed carbon fiber spar that ensures wing rigidity in high-G maneuvers. To achieve the same dihedral as the real aircraft, the ASW-17 was designed with a specialized CNC aluminum spar joiner- allowing the aircraft to maintain its wing geometry during demanding flight routines. Performance-wise, a high-quality Hobbywing 40A ESC paired with a Predator 3541-750KV motor provides ample power with a 4S pack to perform most aerobatic maneuvers. If efficiency, stability and aerobatic capabilities are what you seek in a glider, look no further than the FMS 2500mm ASW-17!

KST X08 PLUS servo

 

The KST X08 Plus is a very powerful yet lightweight (9.5 g) wide voltage metal cased, metal geared servo.

 

Features

  • Slim 8 mm body
  • Good for F5J gliders, electric racers and all models with thin flying surfaces
  • Powerful, yet lightweight design
  • Good torque and speed
  • Metal gears

Product Information

 

The KST X08 Plus is based on the well regarded KST X08 V5 servo but with a larger motor fitted. It is especially good for F5J gliders, electric racers, and all models with thin flying surfaces. Despite being only 8 mm thick the powerful coreless DC motor and gearing provide good torque and high speed. The X08 Plus can be operated from a voltage as low as 3.8V (1S LiPo) or as high as 8.4V (2S LiPo). KST servos have excellent geartrain machining tolerances, and this servo is completely slop free, and equal to products costing twice as much. This servo has metal gears and is very durable.

The KST X08 Plus' high torque, good speed, and minimal 8mm thickness are what makes it suitable for many high-performance gliders (F5J, F3J), pylon racers and EDF applications. With up to 5.3 kg.cm torque the KST X08 is appropriate for F5J, F5D, F3J and many other types of high-performance models.
