E-flite 4-Site 3D FF RC Airplane Introduction
In the early 2000s, flat foamy models were extremely popular because they could be scratch-built from foam sheets you could buy in many stores. Today, most foam models are fully moulded sport and scale aircraft – and few can match the unique capabilities and performance of flat foam models, especially those designed and built for aerobatic plus 3D flying! The E-flite® 4-Site 3D FF (Flat Foamy) 800mm is based on the original F3P and UMX models and is a biplane alternative to the popular Eratix 3D FF that's taken the market by storm. It's perfect for experienced pilots who already build and fly flat foam models, intermediate pilots who are interested in them but don't want to undertake a complicated build, and less experienced pilots who have always wanted to try but were intimidated by the extra effort and skills required to buy, build and fly such a model. The 4-Site 3D FF is the easiest to fly, most convenient, and best value in a biplane flat foamy model yet!
E-flite 4-Site 3D FF RC Airplane 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!

- Landing gear snaps into place for easy installation, removal and replacement


Bind-N-Fly Completion Level Advantage
Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!
This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX¬ receiver featuring AS3X+ (Artificial Stabilization-3-aXis+) technology that works behind the scenes to smooth out the effects of wind and turbulence. The result is a heightened sense of stability and precision that makes you feel like you're flying a much larger, expertly tuned aircraft.
If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE¬ Select flight envelope protection technology built into the receiver. No programming is required. Simply change up the binding sequence as directed in the manual.
With SAFE Select enabled, you get:
Pitch and Bank Angle Limits
- These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.
Automatic Self-Leveling
- The airplane instantly returns to and holds level flight when the sticks are released and in the centre position. It's also helpful for keeping the wings level during takeoffs/launches and landings.
Easy Switch Assignment-No Complex Programming Required
- The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn't require any complex programming and takes just a few seconds.
If you don't want to enable the SAFE Select features, just bind the receiver normally and it will function like a standard AS3X+ receiver.
- Wingspan: 800 mm

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
- Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
