Spek­trum DX8e

Model Airplane News - - PRODUCT WATCH - spek­trum.com

Fea­tur­ing DSMX tech­nol­ogy and easyto-use AirWare pro­gram­ming, the new Spek­trum DX8e is loaded with fea­tures you’d ex­pect with ra­dios cost­ing twice as much. With pro­gram­ming for four model types—air­plane, he­li­copter, sailplane, and mul­ti­ro­tors—the DX8e fea­tures an SD slot (card not in­cluded), so you can share model mem­ory set­ups with just about any other Spek­trum ra­dio user. It has an im­pres­sive 250-model mem­ory, and I es­pe­cially like the way the pro­gram­ming han­dles the mem­ory menu. Nav­i­ga­tion is very easy, as only those mem­ory slots that are dis­played are the ones that have model set­tings saved to them. So should you delete any, you don’t have to scroll down a bunch of empty mem­ory slots or move mod­els around. The DX8e comes with four AA trans­mit­ter bat­ter­ies, a com­plete in­struc­tion man­ual, and an Allen wrench. The DX8e does not come with a re­ceiver, but it is com­pat­i­ble with all DSM2 and DSMX Spek­trum re­ceivers.

UNIQUE FEA­TURES

The Spek­trum DX8e is very sim­i­lar to the pop­u­lar DX6e. It looks sleek and is well bal­anced in your hands. While car­ry­ing the DX8e, the tiltable an­tenna and hand­hold lay­out give you a se­cure grip. It has dig­i­tal trims for the four main con­trols and the fa­mil­iar Spek­trum roller/switch to the right of the main dis­play screen, and two flush Clear and Back but­tons on the left make nav­i­gat­ing the menus in­tu­itive for speedy model setup. Hav­ing eight chan­nels pro­vides ad­di­tional flex­i­bil­ity when set­ting up mod­els with func­tions like the flaps and re­tracts while still pro­vid­ing ad­di­tional chan­nels for other func­tions and mix set­ups.

The ra­dio has a clean lay­out, and it has all the stan­dard two- and three-po­si­tion switches for mixes, aux­il­iary chan­nels, and dual-rate se­lec­tion. The Bind but­ton is at the up­per left, and the On/Off power switch is re­cessed. When switch­ing off the trans­mit­ter, you hold the switch down for a few sec­onds, so there are no ac­ci­den­tal power in­ter­rup­tions. The screen dis­play is the same easy-to-read lay­out of other Spek­trum ra­dios and in­cludes model name, a timer (ac­ti­vated by the throt­tle stick), a bat­tery-volt­age icon and read­out, four main trim-po­si­tion bars, a to­tal-ra­dio-on timer, and a large model-type icon. I es­pe­cially like the new fea­ture of be­ing able to choose the type of icon you want. Un­der the Sys­tem Setup menu, you can scroll down to the Air­craft Type sub­menu. This is where the wing and tail types are se­lected, but down in the lower right cor­ner is the Next se­lec­tion. Click there and the Air­craft Im­age screen is brought up. In to­tal, there are 36 icons to choose from, in­clud­ing sport and scale mod­els, WW II war­birds, jets, he­lis, and mul­ti­ro­tors. Ad­di­tional fea­tures in­clude quad-bear­ing gim­bals with mul­ti­point front-ac­cess ad­just­ments, a gim­bal mode-change switch, and a wire­less buddy-box trainer func­tion.

AIR­PLANE PRO­GRAM­MING

The list of fixed-wing pow­ered air­plane fea­tures in­cludes seven wing types (nor­mal, dual aileron, flap­eron, one aileron/one flap, two aileron/two flap, elevon a, and elevon b), six tail types (nor­mal, V-tail A, V-tail B, dual el­e­va­tor, dual rud­der, and dual rud­der/ el­e­va­tor), a flap sys­tem with el­e­va­tor com­pen­sa­tion, three flight modes, dual rates and expo, seven-point throt­tle curve, three pre­set mixes (rud­der-toaileron/elevon, aileron-to-rud­der, and el­e­va­tor-to-rud­der), four pro­gram­mable mixes (nor­mal or curve), and AS3X tech­nol­ogy gain ad­just­ments with­out a PC. It can also wire­lessly “buddy box” with other DSMX/DSM2 trans­mit­ters.

BUILT-IN TELEME­TRY

The built-in teleme­try func­tion pro­vides re­al­time in­for­ma­tion on things such as bat­tery volt­age, sig­nal qual­ity, mo­tor tem­per­a­ture, and more. You can also set up alerts to let you know when spe­cific teleme­try val­ues reach or ex­ceed lim­its that you de­fine.

For the drone pilot, there is mul­ti­ro­tor flight-mode setup and an in­te­grated FPV racing lap-timer func­tion. While fly­ing a cam­era drone, you can as­sign gim­bal func­tions to a sec­ond cam­era trans­mit­ter with the wire­less bud­dy­box func­tion so that you can fo­cus on pi­lot­ing your drone and main­tain­ing vis­ual con­tact while your copi­lot can line up the shots. You can also link with spe­cially equipped Spek­trum FPV head­sets to wire­lessly control head track­ing and re­motely change cam­era video fre­quen­cies.

BOT­TOM LINE

Af­ter putting it through its paces, I re­ally like the feel and per­for­mance of the DX8e. Priced at $199.99, it is a great en­try-level pro­gram­mable com­puter ra­dio that’s easy to pro­gram. If you are look­ing for a new 8-chan­nel sys­tem, I highly rec­om­mend the Spek­trum DX8e.—Gerry Yarrish

The new Spek­trum DX8e is a ver­sa­tile and easyto-pro­gram 8-chan­nel ra­dio sys­tem.

The switch and control-knob lay­out will be fa­mil­iar to any Spek­trum ra­dio user.
