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. 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!
This model is equipped with Horizon Hobby and Spektrum exclusive AS3X (Artificial Stabilization – 3-aXis) and optional-use SAFE (Sensor Assisted Flight Envelope) Select technologies, and when SAFE Select is turned on using the mode switch (B on the Spektrum InterLink DX controller) it offers:
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 center position. It’s also helpful for keeping the wings level during takeoffs and landings.
