Overview of the dx6i and dx6e

The dx6i was released first in 2010 and helped pioneer Spektrum’s broad appeal into the entry-level RC market. It delivers a simple interface and reliable DSMX 2.4GHz communication with Spektrum aircraft out of the box.

The dx6e came later in 2016 as the updated, enhanced version of the dx6i. It offers more programming options, a better screen, voice alerts, model memory, and other advanced capabilities.

Both transmitters utilize Spektrum’s proven DSMX® technology with frequency hopping for long-range control that resists interference. They can bind to the same range of BNF planes, helicopters, drones, cars, and more from brands like Blade, E-flite, Hangar 9, ECX and others.

Background on Spektrum RC Transmitters

Spektrum radios have been produced by Horizon Hobby since 2005 under the brand name JR. They utilize Direct Sequence Spread Spectrum (DSSS) technology to deliver reliable control of RC models on the 2.4GHz band.

Spektrum’s widespread adoption of 2.4GHz represented a major shift away from the congested 72MHz and 75MHz bands used previously by most RC systems. It paved the way for standards like DSMX to take over the hobby.

Today Spektrum offers a range of transmitters across different price points and features sets. The dx6i and dx6e sit at the entry-level end catered towards new RC pilots and sport flying applications. Higher models like the DX6 and DX8 have more programming flexibility while the DX9 and DX18 are geared for professionals.

Main Differences Between the dx6i and dx6e

Although the dx6i and dx6e share similarities in their core functionality, there are some notable differences between the two transmitters.

Physical Design and Buttons

The dx6i features a rounded, sleeker case design compared to the more boxy styling of the dx6e. The dx6e is overall larger and adds a lanyard post to help keep the radio secure around your neck.

Both have similar button layouts but the dx6e has larger gimbals sticks that are smoother and more precise for control inputs. The toggle switches are also improved on the dx6e with sturdier action.

Software Features

The dx6i runs simpler firmware optimized for BNF binding and flying. The dx6e adds more adjustable settings through its updated software, including:

• 10 model memory slots
• Programmable mixers and expo rates
• Built-in timer and stopwatch
• Voice alerts for telemetry feedback

This allows for more customization when setting up models. The dx6e also has telemetry capability to display real-time flight data.

Telemetry Capabilities

The dx6e includes built-in telemetry that can report back battery voltage, altitude, temperature and other sensor information from compatible Spektrum aircraft.

This allows monitoring key parameters in flight without needing to add-on a separate module. The dx6i does not have any native telemetry features.

Transmitter Specs and Hardware Comparison

Beyond the core differences in features, there are some hardware distinctions between the dx6i and dx6e worth comparing.

Transmitter Case and Shape

As mentioned earlier, the dx6i has a smooth, rounded case shape that fits nicely in your hands. It measures approximately 7-1/4 inches wide by 5-1/4 inches deep.

The dx6e is larger at 8-1/4 inches wide and 5-3/4 inches deep. It uses a polycarbonate plastic shell that is contoured with some hard angles for grip.

Both transmitters come in at around 13 ounces in weight including batteries. The dx6e gains a little bulk from the added features but is still comfortable to hold.

Controls and Switches

The primary gimbal sticks are improved on the dx6e with longer throws and smoother bearings. The toggle switches are also more refined making them easier to flip through different positions.

The button membranes have crisp feedback with audible clicks when pressed. One nice upgrade is the 3-position slider switch on the dx6e which is great for changing rates and presets.

Internal Hardware and RF Performance

Inside, both radios utilize Spektrum’s proven DSMX 2.4GHz technology with diversity antennas to resist signal fades. Their range reaches out to 1.5mi or farther depending on conditions.

The dx6e gets a bump up to 2048 resolution compared to 1024 on the dx6i. This doubles the precision of control inputs from the gimbals and switches.

They share the same 4 AA batteries for around 5-6 hours of use. The dx6e adds an external charge port for recharging NiMH batteries.

Overall the dx6e improves upon the dx6i in hardware quality while retaining Spektrum’s dependable RF link that pilots have come to trust.

Programming and Software Features

The dx6e separates itself from the dx6i most noticeably in its programming capabilities accessed through the software.

Model Memory

The dx6e allows saving settings for up to 10 different models in memory. This lets you easily switch between aircraft without needing to reconfigure each time. The dx6i does not offer model memory.

Mixing and Expo Rates

With the dx6e you can customize mixes between channels and adjust expo rates for smoothing out controls around center stick. The dx6i lacks any mixing or expo adjustment.

Timers and Voice Alerts

The integrated telemetry on the dx6e allows setting timers that can count down and alert you vocally when time periods are reached. Helpful for tasks like fuel management.

Custom Voice Alerts

Any switch or button on the dx6e can be assigned to trigger custom voice alerts. This might be handy for signaling when landing gear is lowered for example.

These expanded programming functions make the dx6e much more capable for dialing in preferences on multiple aircraft. The dx6i keeps things simple with no preset configuration allowed.

Bind-N-Fly Aircraft Compatibility

Since both transmitters utilize DSMX technology, they can bind to all the same Spektrum and bind-N-fly aircraft. This includes a wide range of hobby RC planes, helis, drones and cars.

Aircraft Types Supported

The dx6i and dx6e work with micro-size all the way up to giant-scale Bind-N-Fly models including:

• Sport airplanes – E-flite, Hangar 9
• Trainer planes – Apprentice, Carbon Cub, Aeroscout
• Warbirds – T-28 Trojan, P-51 Mustang
• Aerobatic models – Extra 300, Edge 540
• Gliders – Night Radian, Aerobatic Radian
• Helicopters – Blade 130X, Blade 120SR
• Quadcopters – Blade Indux, Blade Nano QX
• Ground vehicles – ECX circuit stadium truck, ECX amp buggy

Pretty much any Horizon Hobby aircraft with AS3X, SAFE, or DSMX technology will work.

Receivers Compatible with Each Transmitter

Both the dx6i and dx6e can bind directly to all Spektrum DSM2 and DSMX remote receivers. This includes models with:

• Spektrum AR610, AR6270, and AR6370 receivers
• Spektrum AR9030, AR9100, and AR9300 receivers
• Spektrum SRXL2 receivers

So you gain flexibility to fly a huge range of aircraft from other brands by using Spektrum components.

Overall the dx6i and dx6e share broad compatibility with the same RC planes, helicopters, cars and drones out of the box. You are not limited in any way between either transmitter option when choosing Bind-N-Fly models to fly.

Price and Value Comparison

When looking at the dx6i vs dx6e, price is often a major factor for RC pilots on a budget.

Retail Prices

The dx6i has a typical retail price around $200-220. Since it has been out for over 10 years, you can sometimes find it discounted lower from some sellers.

The dx6e came out at around $240 retail and still sells right around that price point today. Occasionally sales might bring it down closer to $200.

Overall the dx6e commands a slightly higher price which reflects the addition of more features. But both deliver good value for a starter-level transmitter.

Overall Value for Cost

For the extra $20-40 investment on the dx6e, you gain a lot of added capabilities that improve the overall experience. Model memory, programmable mixes, voice alerts, and telemetry make the dx6e a better long-term value.

The dx6i is the more affordable option upfront and still offers core functionality. But it may feel limited sooner as your skills progress.
