Package contents
The package contains ready-made complete parts of the E-flite 4-Site 0.8m 3D FF RC aircraft model, with installed components: Brushless motor 2408-1300Kv 14-P, Spektrum Smart Avian 30A IC2 controller, 3x Sub-micro digital servo 9g SA347 (aileron, elevator, rudder), CZ instructions, EN, DE, FR, IT manual.
Characteristics
E-flite 4-Site 0.8m is a typical representative of indoor RC models with flat parts made of EPP. Suitable for 3D acrobatic, sports and slow flying indoors and outdoors. This biplane has a shorter span compared to the popular E-flite Eratix model, but an overall larger wing area with lower surface load for greater maneuverability. Assembly is extra easy, thanks to the latch system. Almost immediately after assembly and adjustment, you can start flying, just add/purchase a 3S LiPo 11.1V 850–1000mAh power battery, charger and RC kit (transmitter and receiver). Servos, motor and controller are installed.

Indoor model airplanes were very popular at the beginning of the new millennium and could be easily and cheaply made from EPS board material Depron. Today, the technology of sports competition specials is completely different, the skeleton of competition specials is ultra-light carbon and the skin is made of micro foil. The flight technique is very specific and the flight characteristics cannot be compared with anything in the world of aviation.
The E-flite® 4-Site 3D FF (Flat Foamy) 800mm builds on the original F3P and UMX models and is a biplane alternative to the hugely popular Eratix 3D FF. It is ideal for experienced pilots who already have experience with flat foam models and for intermediate pilots who are interested in them but don't want to bother with the complexities of building. That's why the 4-Site 3D FF is the most maneuverable, easiest to build, and most affordable indoor biplane yet!
The lightweight and extremely durable EPP airframe is factory-assembled, just snap the finished parts together and screw in the locking screws. The rudders are controlled by three durable servos with metal gears. The propulsion system includes a powerful brushless motor for aerobatic maneuvers and vertical thrust. The Spektrum Avian Smart Lite 70A controller supports telemetry via a compatible receiver (AR631+ included, not included in the package) and a transmitter equipped with Spektrum AirWare (sold separately). The RC model aircraft is small and light enough to fly in gyms and halls, or outside in the garden, parks and sports fields.

Skill Level 3 – Experience Required
Skill Level 3 aircraft like this are suitable for more experienced RC pilots with the skills to build, set up and fly similar class models. This PNP version requires more experience and skill to build and fly than the BNF Basic version, as you must install a receiver that does not already include properly tuned AS3X+ and SAFE Select technologies. It is also not a suitable first aerobatic model. You should have the experience and skill needed to successfully fly aerobatic models such as the E-flite UMX Ultrix, UMX Timber X, T-28 Trojan 1.1m, Sportix 1.1m, Timber X 1.2m, or other models in a similar class before attempting to fly the 4-Site 3D FF.

Plug-N-Play version
The Plug-N-Play (PNP) version comes with a factory-installed power system and servos ready to connect to a compatible receiver of your choice (sold separately), plus a transmitter and batteries you supply (also sold separately). Simply install the receiver, complete the final assembly, and you're ready to fly!

Smart™ technology
The exclusive Spektrum™ Avian™ Smart Lite ESC provides a range of real-time telemetry data, including motor RPM, current draw, flight battery voltage and more, via the Smart Receiver and compatible Spektrum transmitter equipped with Spektrum AirWare™ technology (DX6e, DX8e, DX6 G2/3, DX8 G2, DX9, NX6, 8 and 10, iX12, iX20 and more). (Transmitter and receiver not included.)

Unique abilities
Like other indoor models made of board materials, the 4-Site is capable of slow flight, sport and basic aerobatics, and even aggressive 3D flying - all in one flight! It offers both a relaxed flying and an adrenaline-pumping flight experience, intermediate to experienced pilots will appreciate whether flying indoors in gyms or outdoors in meadows, parks, sports fields, etc.

High performance
The installed brushless motor with optimal parameters provides the model with more than enough thrust for unlimited vertical performance and 3D capabilities with LiPo 3S batteries! Use an 850 mAh LiPo battery to keep the weight low or up to a 1000 mAh LiPo battery for longer flight times.

Easy assembly
Unlike other similar flat foam models that are sold as kits without power and control components, the 4-Site FF comes factory-assembled with a motor, ESC and servos installed. All you have to do is add a receiver compatible with your transmitter, complete the quick and easy final assembly with snap-on parts and screws. So there's no glue, tape or special tools required - and you'll be ready to fly in less time than you can charge your batteries!

Durable construction
Thanks to the carbon fiber construction and high-density EPP reinforced composite, a lightweight yet rigid and durable airframe has been created. In the unfortunate event that you damage any part of the airframe, repair is relatively easy. A wide range of spare parts are also available.

We recommend buying
To get started, you need a 4+ channel RC kit (receiver and transmitter), a 3S LiPo 850-1000mAh power battery with IC2 connector, and a compatible charger.

Recommended RC kits Spektrum
For pairing models in PNP (ARF) versions, we recommend modern programmable RC kits SPEKTRUM:
- Spektrum DX6e DSMX 6-channel DX series transmitter with telemetry, 250 models in memory + AR620 6CH Sport receiver.
- 14-channel NX+ series transmitter Spektrum NX7e+ DSMX with the latest trends, Smart Technology compatibility + Spektrum AR6610T 6CH receiver.
- 20-channel NX+ series transmitter Spektrum NX8+ DSMX with the latest trends, Smart Technology compatibility, USB port and WiFi connectivity + Spektrum AR8020T 8CH receiver.

Recommended batteries
To power the model, we recommend a 3-cell LiPol battery (11.1 V).
- LiPo battery Spektrum Smart G2 LiPo 11.1V 850mAh 30C IC2 with Smart G2 technology
The battery contains an IC2 connector, an IC3/IC2 adapter is required to connect to Spektrum Smart chargers.
Spektrum batteries with Smart technology are currently the most modern and safest way to maintain and charge batteries. Find out the benefits of Spektrum Smart technology here.

Recommended chargers for conventional LiPol and Smart batteries
If you decide to use modern Smart LiPo batteries in your RC model airplanes or helicopters, or to charge your batteries from other manufacturers, then we recommend these chargers:
- Spektrum S155 mains charger with one output 1x 55W .
- Spektrum S1100 mains charger with one output 1x 100W .
- Spektrum S2100 mains charger with one output 2x 100W .
- Spektrum S2200 mains charger with two outputs 2x 200W .

Accessories for normal operation
For normal operation of flying RC models you need suitable adhesives, a tool kit and a storage case for LiPol batteries. From our range we recommend a quality set of 1.5/2.0/2.5/3.0mm Allen screwdrivers and Modelcraft Phillips screwdrivers (set of 6). For assembly, Modelcraft mini pliers in a case (set) will certainly come in handy, and for cutting, Modelcraft cutting knife with A6 washer.
For quick repairs of aircraft models, we recommend a fast-curing 4-minute Epoxy glue. From our offer, we recommend Speed Epoxy 4 min. 71g

Protective covers for batteries
Protective packaging is designed to reduce the risk associated with transporting and charging batteries. LiPo batteries can provide high discharge currents and have a large capacity while maintaining small dimensions and low weight. LiPo batteries are particularly susceptible to mechanical damage and therefore need to be carefully protected.
