PHAZER Great Planes Set your transmitter flight settings to fun! By Don Belfort PHOTOGRAPHY: DON BELFORT I
first saw the Phazer by Great Planes
www.greatplanes.com streaking through the sky at a jet fly-in this past summer. My first thought was that it was a Mi-
rage 2000 or some type of scale design. The Phazer is an Almost Ready to Fly EDF de- signed for speed and simplicity. It is fast and easy to assemble, it includes the well proven HyperFlow 56mm fan unit and an Ammo
24mm 3790Kv brushless inrunner which will draw around 30 amps on a 4S Li-Po. The sleek and lightweight fiberglass fuse- lage/tail has the trim painted on for a very high quality finish along with a magnetical- ly attached canopy for easy battery access. The wings are built-up balsa covered in MonoKote, and plug in with an aluminum joiner. A decal sheet is included with multi- ple marking options left to the modeler. The Phazer can be hand launched or launched with the recommended and included bungee system.
I opened the Phazer box with my flying buddies present. They were all impressed with the excellent packaging of the compo- nents and their grouping for easy assembly, not to mention the high end quality of the airframe.
Great Planes lists the Phazer’s speed as 90+ mph which requires advanced flying skills along with an approved AMA flying site. I would suggest that you have flown not

only fast but small aircraft or have an expe- rienced pilot test fly your model. The easy to read manual takes you
through the safety precautions related to high performance EDFs and reviews what equipment will be needed to complete your Phazer. I like to look through the manual of any new project before I start and recom- mend you do the same. A transmitter with elevon mixing, two servos with a 20-ounce torque rating, two 4-inch servo extensions, a 35-amp brushless speed control and a 4S 2200 mAh 30C Li-Po are required. For the review I used a Futaba 7C system and Futa- ba S3175 digital micro servos with Futaba 75mm extensions, a Great Planes ElectriFly Silver Series 35-amp brushless speed con- trol and Flight Power 4S 2200 mAh 30C EON-X Li-Po. All electric components were connector equipped to create a plug and play power system for ease of assembly. The proper adhesives are listed in the manual for each subassembly and should be followed exactly.
Construction begins with the fan assem- bly. The center body of the fan shroud will need to be slightly modified to accommo- date the Ammo’s 24mm diameter which the manual details with both text and pic- tures. Pay attention to the fan rotor adapter set screw procedure to avoid hav- ing your fan come off in flight, which al-
