Opterra e-filla 2.0m SAFE Select BNF Basic

Advanced aerodynamics, lightweight construction

At the heart of the Opterra's amazing capabilities is the advanced aerodynamics that determined its appearance. In addition to the effective wing profile, the ailerons and rudders on the model's fuselage help with easy handling. The turbulators near the leading edge of the upper part of the wing and just in front of the elevons in the lower part of the wing, increase stability and controllability at low speed. The airframe itself is made of carbon-reinforced hollow material Z-Foam ™, which ensures minimum weight while maintaining strength and rigidity.

Easy to assemble and transport

Assembly is very simple and fast, the model is disassembled and easy to store, it is divided into a centerplane and right and left wing. Assembly or disassembly can be done in minutes, the shipping box is designed as a case with a handle for efficient transport.

Powerful AC motor with tilting propeller

The large stable and well-flying model is powered by a 10BL 1300 rpm / V AC motor with a push-tilt propeller and an E-flite 40A regulator. the power unit has more than enough power to carry the camera's payload or for sports acrobatics.

There are 3 mounting stations for the camera

The model is designed for FPV flying, so in the front part, after removing the tip, a space is prepared for the location of the camera and video signal transmitter. The package includes two forward-facing stations for FPV or HD cameras. There is also a downward shaft in the abdomen, designed for GoPro Hero 3, Hero 4 and similar HD cameras. Due to the location of the thruster, the video is not disturbed by the rotating propeller.

Thanks to the used receiver with AS3X and SAFE technology, flight envelope protection with a limit of tilt and climb or descent can be used. The model cannot be brought to extreme flight positions and after returning the control levers to neutral, the model will flatten into horizontal flight. This function can be assigned a switch and SAFE / AS3X enabled or AS3X stabilization only and the model can be controlled without restriction.

Recommended transmitters Spectrum

We recommend modern SPEKTRUM programmable transmitters for pairing the BNF version model:

• 
  
• DX Spectrum DX6e DSMX 6-channel telemetry transmitter, 250 models in memory .
  
• 6-channel transmitter of the NX Spectrum NX6 DSMX series with the latest trends, Smart Technology compatibility, USB port and WiFi connection options .
  
• 8-channel NX series transmitter Spectrum NX8 DSMX with the latest trends, Smart Technology compatibility, USB port and WiFi connectivity .
  

Recommended batteries

We recommend a 3-cell (11.1 V) LiPol drive battery to power the model.

• 
  
• For economical flying LiPo battery Black Magic LiPol 11.1V 2200mAh 25C with EC3 connector.
  
• Smart LiPo battery Spectrum Smart LiPo 11.1V 2200mAh 30C IC3 with technology Smart
  
• For longer flight time LiPo battery Spectrum Smart LiPo 11.1V 3200mAh 30C IC3 with Smart technology
  

Spektrum batteries with Smart technology are currently the most modern and safest way to maintain and charge batteries. You can find the advantages of Spektrum Smart technology here.

Recommended chargers for conventional LiPol and Smart batteries

If you decide to use modern Smart LiPo batteries in RC models of planes or helicopters, or to charge your batteries from other manufacturers, then we recommend the following chargers:

• 
  
• Charger with mains power supply Spektrum S150 with one 50W output.
  
• Charger with mains power supply Spektrum S1100AC with one output 1x100W .
  
• Charger with mains power supply Spektrum S2100 with two outputs 2x 100W .
  

Recommended modern powerful chargers for Smart batteries

• 
  
• High performance AC charger Spektrum Smart G2 charger S1400 1x400W AC with one output 400W .
  
• High performance AC charger Spektrum Smart G2 charger S2200 2x200W AC with two outputs 2x200W .
  

There is a reduction for charging IC5 / IC3 Spectrum conversion cable IC5 device - IC3 battery 10cm 10 AWG.

Recommended chargers for conventional LiPo batteries

If you decide to run the model on conventional LiPo batteries , we recommend using universal chargers with a power of at least 50 W.

Dynamite Prophet Sport charger with two 50 W outputs

Accessories for normal operation

For normal operation of flying RC models, you need suitable adhesives, a set of tools and a case for storing LiPol batteries. From our range we recommend a quality set of Allen screwdrivers 1.5 / 2.0 / 2.5 / 3.0mm and Modelcraft Phillips screwdrivers (set of 6). The Modelcraft mini pliers in a case (set) and a Modelcraft cutting knife with an A6 washer will certainly be suitable for assembly.

For quick repair of aircraft models, we recommend the fast-curing 4-minute Epoxy adhesive. From our offer we recommend Speed Epoxy 4 min. 71g

Protective covers for batteries

Protective covers are designed to reduce the risk associated with transporting and charging batteries. LiPo batteries can, while maintaining small dimensions and low weight, provide high discharge currents and have a large capacity. The LiPo battery is prone to mechanical damage and therefore needs to be thoroughly protected.
