A high power electric system such as the BVM 4000 watt EVF does cause emi problems for radio's operating in the 72Mhz band.
Multiple RF filters have to be applied to the power cables, external antennas are required and the receiver must be distanced from the noise source. Even with these adaptations, the ground test range is somewhat impaired.

Not so with Spektrum®

This very simple, very light weight installation yields double the manufactures recommended minimum ground range. And, the link is absolutely solid.

The DX7 programming is easy and is complimented by a user friendly operating manual. It is the right radio for a high performance electric jet and it is very reasonably priced.

BVM stocks the DX7 and the correct servos and extensions to equip our E-jets.

	THE TRANSMITTER: The DX7 DSM2 transmitter features airplane and heli software, 20-model memory and all the programming functions you would ever need for anything requiring 7 channels. And the large dot matrix, LCD screen makes accessing and using the software simple and straightforward.
THE SERVOS: The four DS821 servos that come with the DX7 put out an impressive 72 oz/in of torque that is suitable for a wide range of electric, gas or glow aircraft. Their digitally precise output is further enhanced by a robust, high-tech resin gear train that is exceptionally durable for reliable performance flight after flight.
	THE AR7000 RECEIVER: The AR7000 Dual Receiver is capable of providing outstanding signal reception beyond visual range, so you can rest assured you have locked-in, precise control no matter how fast you fly. Features: 7 Channels Internal and remote receiver DuaLink ModelMatch prevents flying a model using the wrong model memory (feature does not work with module systems) ServoSync (feature does not work with module systems) SmartSafe fail-safe system

Programming Features
	3-Position Flap Mixing: The DX7 incorporates a three-position flap system that allows the flap and elevator positions to be preset in all three switch positions. An auto function automatically retracts the flaps when the throttle is raised above a preset point such as during an aborted landing or touch-and-go.
	Switch Assignment: The DX7 offers switch assignment that lets you conveniently combine dual rates on one of many switches or program them to be activated separately.
	Single Screen Dual Rate/Exponential: Punch in dual rate and exponential values in the same screen for aileron elevator and rudder and see the result clearly and graphically depicted on the displayed curve.
	5-Point Heli Throttle and Pitch Curves: Four flight modes (normal, stunt 1, stunt 2 and hold) are available, each with its own five point throttle and pitch curve. Graphical depiction of the curves makes adjustments clear and easy to understand.
	Servo Monitor: Keep real time tabs on each channel’s control position, direction of movement and mixing relationship with this all-in-one servo monitor that can help you visualize mixes before flying.
	Gyro Sensing: The gyro function allows two gyro gain presets that can be automatically accessed via flight modes or with the rudder dual rate switch.
