PRODUCT OVERVIEW
The E-flite 4-Site 3D FF (Flat Foamy) 800mm offers the aggressive aerobatic plus smooth sport and slow-flying performance of similar class models - without all the hassles of buying components for and building one! It bolts and snaps together so it can be ready to fly in less time than it takes to charge a battery compared to the glue, tape, and many hours it usually takes to assemble other "flat foamy" aircraft. It's a biplane alternative to the best-selling Eratix 3D FF with a shorter wingspan but more wing area for lower wing loading overall. Its lightweight yet extremely durable EPP airframe is mostly factory-assembled and includes three durable and precise metal-geared servos on all the control surfaces. The factory-installed power system features a 3S-compatible brushless motor matched to a Spektrum Avian Smart ESC compatible with Smart and non-Smart 850-1000mAh batteries. The BNF Basic version is also equipped with an AR630+ receiver to deliver real-time telemetry data, enhanced AS3X+, and optional-use SAFE Select technologies. It's small enough and light enough to be flown indoors in gymnasiums and other similar spaces or outdoors in yards, parks, and sports fields, making it a versatile addition to the hangar for a wide range of pilots!

FEATURES
- The easiest to buy, assemble and fly biplane flat foamy model yet - capable of slow cruising, sport flying, basic and all-out 3D aerobatics
- Specially tuned brushless motor that's factory-installed and ready for use with popular 3S 850-1000mAh batteries
- 30-amp Spektrum Avian Smart Lite ESC provides real-time battery voltage, current, RPM and other data via compatible receivers and transmitters
- Spektrum AR630+ receiver with fly-by range telemetry and industry-leading DSMX technology (BNF Basic Only)
- Easier to fly with innovative and optional-use SAFE Select flight envelope protection (BNF Basic Only)
- Receiver loaded with a Smart Transmitter File that allows you to import all settings for NX and iX series transmitters during the binding process (BNF Basic Only)
- The unmatched stability and locked-in feel of exclusive and enhanced AS3X+ technology (BNF Basic Only)
- Compatible with the Spektrum DXS transmitter included with many of the most popular E-flite and HobbyZone trainer airplane models
- Extremely durable yet lightweight, high-density EPP airframe with carbon fiber and composite reinforcements
- Factory-finished in a high-contrast, high-visibility trim scheme for excellent orientation
- Three factory-installed metal geared and digital servos for all control surfaces
- Fast and easy assembly unlike similar class models - no glue or tape required
- Landing gear snaps into place for easy installation, removal and replacement


BNF Basic - Skill Level 2
Skill Level 2 aircraft, like this one, are suitable for RC pilots with the experience and skills to assemble, set up, and fly similar class models. Although the 4-Site 3D FF is easier to assemble and fly than other flat foamy models, it's not a suitable first-ever RC aircraft for new pilots or a first-ever aerobatic/3D model for low-time RC pilots. You should have the experience and skills necessary to successfully fly aerobatic models like the E-flite UMX Ultrix, UMX Timber X, T-28 Trojan 1.1m, Sportix 1.1m, Timber X 1.2m, or other similar class models before attempting to fly the 4-Site 3D FF BNF Basic version.
PNP - Skill Level 3
Suitable for more experienced RC pilots with the skills to assemble, set up, and fly similar class models. This PNP version requires more experience and skills to assemble and fly than the BNF Basic version because you must install a receiver that does not already include properly tuned AS3X+ and SAFE Select technologies. It's not a suitable first-ever RC aircraft for new pilots or first-ever aerobatic/3D model for low-time RC pilots. You should have the experience and skills necessary to assemble and successfully fly models like the E-flite UMX Ultrix, UMX Timber X, T-28 Trojan 1.1m, Sportix 1.1m, Timber X 1.2m, or other similar class models before attempting to fly the 4-Site 3D FF PNP version.

Uniquely Capable
Like other flat foamy models, the 4-Site 3D FF is capable of slow cruising, smooth sport flying, basic aerobatics, and even aggressive 3D flying-all in the same flight! It offers a truly "mild to wild" flight experience that intermediate to experienced pilots will appreciate, whether indoors in gymnasiums or outdoors in yards, parks, sports fields, and beyond.

High Performance
The factory-installed brushless power system features a specially tuned Spektrum outrunner motor. This power system delivers plenty of thrust for unlimited vertical and 3D performance with 3S 850-1000mAh batteries!

Durable Design
Three factory-installed digital servos with metal gears on all the control surfaces, plus construction with carbon fibre and composite-reinforced, high-density EPP, deliver a lightweight yet stiff and durable airframe. In the unfortunate event you damage any airframe parts or components and can't repair them, a full line of replacement/spare parts is readily available.

Smart Technology
The 4-Site 3D FF is equipped with an exclusive Spektrum Avian Smart Lite ESC that can provide a variety of real-time power system-related telemetry data including motor RPM, current, overall battery voltage, and more - with Smart and non-Smart batteries - via compatible receivers (including the AR630+) and Spektrum AirWare equipped transmitters (including the DX6e and 8e, DX6 G2/3 and 8 G2, the DX9, NX6 to 20, iX12 to 20 and others) while you fly.

Easy Assembly
Unlike other flat foamy models that are only available as kits without power and control components, the 4-Site 3D FF arrives mostly factory-assembled with the power system, servos, and receiver (BNF Basic version only) installed. All you need to do is finish some quick and easy final bolt/snap-together assembly-without the use of glue, tape, or special tools-and you'll be ready to fly in less time than it takes to charge a battery!
