Up Sky Runner Hangar Rat Viper Conversion Acro-Bipe Micro Taxi Blimps Todd's Tiny Classic Bipe

The E-flite UMX Extra 300 3D makes the dream of a 3D plane that flies almost anywhere a reality. With a flying weight of barely over an ounce, including battery, it is slow and light enough to fly extreme 3D maneuvers in spaces no larger than a dining or conference room.

Its ingenious laser-cut foam airframe, designed by ETOC champ Seth Arnold, makes it all possible. The model is available in either a BNF version that includes a battery and charger or BNF Basic version for the pilot who already has their own battery and charger. It comes completely assembled with a punchy 8.5mm coreless brushed motor and Spektrum? AR6400L Ultra Micro DSM2® Receiver/ESC installed. Built-in long-throw servos on the AR6400L drive the elevator and rudder while two independent Spektrum AS2000L long-throw ultra micro servos drive the ailerons.

The only component needed to complete this BNF package is a 4-channel DSM2 transmitter. Dual rates and exponential programming are recommended.

The Ultra Micro eXtreme (UMX) Beast® is a small-scale recreation of one of the most awe inspiring airplanes on the airshow circuit today. Designed by aerobatic world champion Quique Somenzini, it delivers high-powered aerobatic excitement that will put a grin on the face of any intermediate to experienced RC pilot.

At the heart of its phenomenal performance is a brushless motor, propeller and battery combination that delivers a spine-tingling thrust-to-weight ratio. This incredible power output, combined with its well-balanced controls and carbon reinforced wing, allow the UMX Beast to achieve a level of precision and performance that has more in common with its giant-scale Hangar 9® twin than any other ultra micro.

The Great Planes VFO (Vertical Flying Object, aka POGO) is a different kind of airplane that takes off vertically from the ground and then flies forward like an airplane. Although meant to be an indoor flyer, it can also be flown outdoors on very calm days.

 The foam with carbon fiber bracing kit itself is inexpensive but it requires the following support items:

·    ElectriFly Rimfire Brushless 300 Motor (GPMG4505)
·    ElectriFly Silver Series 12A ESC (GPMM1810)
·    ElectriFly BP Series 11.1V, 300mAh LiPo Pack (GPMP0701)
·    Futaba S3114 Micro High-Torque Servos (4) 
·    APC 9x4.7 Slo-Flyer Propeller (APCQ5010)

The VFO uses several mixes to synchronize all four control surfaces so a programmable transmitter is required. Elevon mixing is used on the "wings" to obtain normal flight and the second rudder surface is mixed from an AUX channel to match the rudder control. The final two mixes are used to allow the aileron channel to additionally swing the two rudder surfaces. In this manner, all four control surfaces follow the same aileron direction for rolls. Although three P-mixes are needed to accomplish this setup, it is still possible to leave out the last aileron-to-rudder mix so that only 3 of the 4 control surfaces follow the aileron stick. This reduction allows lower-end transmitters to be used on the VFO with minimal ill effect on rolls.

Although the VFO is meant to be a hover trainer, it is not meant to be a general flying trainer. That being said, if you have intermediate flying skills, the VFO is a great way to learn to hover and coordinate rudder turns. Both intermediate and advanced pilots will have a great deal of fun with the VFO as it can perform many unusual stunts and maneuvers. It is a unique design that utilizes economical LiPo packs and components.


The ParkZone Sukhoi Su-26m BNF is the first 4-channel Ultra-Micro flyer to utilize Bind-N-Fly DSM2 technology that will thrill experienced pilots with its amazing aerobatic capabilities. Based on a Mike McConville design, this exciting addition to ParkZone's family of Ultra-Micro aircraft flies like a much bigger plane.

The Sukhoi has been engineered for a true 4-channel experience, with its remarkable precision control making it perfect for flight in a large yard or gymnasium or even a park on a calm day. All you do is charge the included 110mAh Li-Po battery and bind the plane to one of the many compatible DSM2 transmitters. From rolling circles, loops and snap rolls to aileron rolls, spins and inverted flight, the maximum aerobatic performance of the Ultra-Micro Sukhoi Su-26m is unlike anything else this size.

The Blade mCX S300 is another new product in E-flite's outstanding line of electric aircraft. It comes in a Ready-To-Fly (RTF) version that includes a 4-channel DSM2 transmitter or a Bind-N-Fly (BNF) version that allows experienced pilots to utilize their own DSM2 transmitter. This tiny helicopter offers unsurpassed stability and incredible control through its coaxial, counter-rotating head design and Spektrum' 2.4GHz DSM2' control. It can be flown almost anywhere indoors thanks to its 7.5-inch rotor span and one ounce flying weight.

The new ParkZone Vapor is an exciting innovation from Horizon Hobby that offers both convenience and ease of flight. It is truly an ultra-micro flyer for everyone! The Vapor is small enough, and slow enough to be flown in a basement, garage, living room, or other indoor spaces as well as outdoors in low wind conditions.

The Vapor comes in a Ready-To-Fly (RTF) version that includes a 3-channel DSM2 transmitter or a Bind-N-Fly (BNF) version that allows experienced pilots to utilize their own DSM2 transmitter.

Picoo-Z Micro Heli

The SilverLit PicooZ micro helicopter is available at Radio Shack for $40. It is a 2-channel proportional control InfraRed system that only needs 6 AA batteries in the transmitter. The heli recharges a single built-in LiPo cell from a cable in the transmitter. I only needed to add a single silver sticker (supplied) under the nose for reasonable control in a living room size area. Interesting technology from the toy industry!

For modifications and spare parts, visit the PiccoZ Toolbox.


When I received one the new Wattage Micro Flyers from Hobby People, I was immediately impressed with the degree of integration in this Ready-To-Fly (RTF) package. The Micro Flyer is a very small indoor or outdoor radio controlled (49MHz) flying plane that is powered by a small electric motor and a rechargeable 150mAh Lithium battery.

The design is perhaps the world's first mass-produced RTF micro-flyer at an all-up weight of only 31 grams (about an ounce). The Micro Flyer's direction is controlled by a magnetic actuator mounted in the rudder.

The new Micro Joule (MJ) components are perhaps the smallest in micro-flight technology ever produced for easy plug-n-play usage. The MJ servos weigh about 0.1oz each and the 0.1oz MJ receiver is a single conversion narrow band type that automatically detects the modulation shift for use with Futaba, Hitec, or JR transmitters.

Wattage Lightning (back)


Modified Wattage Lightning (right)

The Micro Gang is a group of inexpensive foam planes that I have converted to R/C. The smallest one in front was an electric free-flight Graupner Micro Taxi that I converted to R/C using the RFFS100 module. On the right is a rubber-powered Acro-Bipe from the Store of Wonder. In the back is a stock Wattage Lightning and on the right is a modified Lightning fuselage. The modified fuselage has full rudder and elevator control using GWS Pico servos and is powered by an Astro Flight 4:1 Firefly coreless motor using the new metal gearbox. The wing is made from two "Lite Wings" from Cloud9 or Takeoff 2000.

A Step-by-Step Guide

 for Converting the Free Flight "Lightning"

to R/C using the RFFS100 Module


Sky Runner Conversion

Wingspan: 23"
Length: 17"
Weight: 1.9oz
Motor: KP-00
Cells: 1s1p or 1s2p 230mAh LiPoly
Radio: RFFS100 Module
Available From: Dynamic Web Enterprises

In my search to find the perfect model for an entry level micro-flight enthusiast, the Sky Runner had many of the qualities that I was looking for:

• Safe pusher configuration with the prop in the rear
• Durable foam design with a shock absorbing rubber nose
• Inexpensive, proven electric free flight flyer with light wingloading
• Taped leading and trailing wing edges for added durability
• Self-contained charging station with On/Off switch
• Plastic nose skid for landing on hard surfaces

Since the stock weight of the free flight electric powered model was only 1.9oz, I knew that to have a successful conversion to R/C, I would need the latest technology. The RFFS100 module, KP-00 motor, and a single 230mAh Lithium Polymer (LiPoly) cell from Dynamic Web Enterprises (DWE) provided me with the technology I needed to convert my model.

After several brief under-powered flights with the stock POT2 motor, I switched to a DX-A (Pico Stick) motor, 7x6 prop, and 8-cell 300mAh NiMH pack. This tiny biplane can now ROG from pavement! Impressive! I later switched to a GWS S1 motor that gives more power with with the 7x6 prop and still doesn't stress the motor at full power.

Here are some pictures of my RTF Lightning with rudder and thrust control. I forgot to weigh my landing gear before so all up it weighs 3.3oz instead of 3.0oz.

Note that my rudder control is a pull-pull configuration using carbon reinforced FireLine. I found a perfect place to mount the GWS Pico servo using 1 screw and a twist tie.

The first picture shows the bottom opened hatch revealing my R4-P receiver and 6-cell 120mAh NiMH pack (blue). The normal clip-on hatch is used to connect the flight pack and access the battery for charging.

The second picture shows the top with the wing removed. The GWS Pico servo is mounted on the existing plastic inserts using only 1 screw and a twist tie. I left all the existing plastic structure in place.

The third picture shows the pull-pull lines coming out of the back window similar to Bob Ruff's control rod.

The forth picture is the finished Wattage Lightning next to the free-flight Graupner Micro Taxi.

Here are some pictures below of my Astro Flight Firefly-powered Lightning. It has been modified for full rudder and elevator control with HS-50 servos. The polyhedral wing is made from 2 of the "Lite" wings from Cloud9.

The plane is RTF at 3.0oz using a 2-cell, 140mAh, LiPoly pack and flies for 10 minutes easy. It will fly both indoors and outdoors.

The servos and receiver sit on a piece of white Depron foam and are held in place by servo tape.
