Finally, a fully-capable 3D micro-sized RC airplane that can be flown virtually anywhere! Perfect for experienced 3D pilots who can simply bind the Ultra Micro 4-Site to their DSM transmitters. This RC airplane is also an affordable solution for aspiring 3D pilots with limited time, space, and money required by larger more traditional 3D birds.

Spektrum's AR6400L

Spektrum first introduced their ultra-micro technology with the release of ParkZone's Sukhoi Su-26m and Ultra Micro P-51 Mustang which utilizes Spektrum's AR6400 ultra-micro receiver and linear servo.

Spektrum extended the throw of the linear servos to suit the requirements of 3D flight with its AR6400L long-throw receiver/ESC/Dual-Servo (servos on RX control the elevator and rudder)and two independent extra long-throw linear servos for the ailerons of the E-Flite Ultra Micro 4-Site.

E-Flite uses its proprietary foam sheets to produce a very light, tuff and durable airframe that is supported by carbon fiber rod. This airframe must be very rigid to withstand the forces of the powerful 8.5mm coreless motor fed by the tiny 3.7V 150mAh Li-Po battery pack.

The end result is something that 3D pilots have been wanting for years. A fully capable 3D aerobat that can be flown in very tight spaces. This thing can do it all including rolling harriers, hovers, knife edge loops, and any thing else your larger models can do!

E-flite’s Celectra 4-Port Li-Po charger and AC adapter

As you can imagine, the E-Flite Ultra Micro 4-site requires quite a bit of current when flying hardcore 3D. This is why it requires a 150mah battery, a bit larger than what previous ultra-micro flyers require. The average flight times are about 4 minutes when flying 3D. The E-Flite Celectra 4-Port Charger along with the relatively inexpensive battery packs makes up for the short flying times. Keep'em charging!

Difference between BNF and PNP Versions

The E-Flite Ultra Micro 4-Site is available as a Bind-N-Fly and as a Plug-N-Play RC airplane.

The BNF version is what you would expect from any BNF airplane. It includes everything you need except the transmitter. The BNF also includes 2 E-Flite 150mAh 1S 3.7V 12C Li-Po Batteries and an E-Flite Celectra 4-Port Charger . You would then bind the airplane to your existing Spektrum Transmitter or other DSM or DSM2 transmitter.

You'll notice in the image to the right that a set of speed brakes are also included with the BNF version of the E-Flite Ultra Micro Site-4. These can be installed if you want to slow the bird down for indoor flying.

The Plug-N-Play version of the Ultra Micro 4-Site is a bit different than most PNP RC airplanes because it actually includes the receiver. This is because the ARF6400L receiver actually entails the aileron and rudder servos. The difference between the PNP and BNF version is that the PNP version does NOT include the 3.7V 150mAh Li-Po battery packs or the E-Flite Celectra 4-Port charger.

Check eBay

Before making any purchases I'd suggest taking a look at what's on eBay. Many times you can be in the right place and the right time and get that unrealistic winning bid that almost makes you feel sorry for the seller!
