This is the Beam E4 V2 "Advance" Flybarless 450 Helicopter Kit. If you're looking for a Heli that is not just a cloned version of an existing design, the Beam E4 V2 Advance is what you've been looking for. From the first CAD drawings, Beam engineers set out to design the E4 V2 to be a stand alone design that was not just different, but better than the leading models both in not only design and quality, but most importantly performance! A no holds barred approach was taken to develop an all original design with no reverse engineering.

Beam designers started by developing a wide spaced main frame, rather than the conventional stacked frame layout to reduce parts count and overall weight. Next, they developed an improved tail belt drive design that runs the belt via a large diameter main pulley for reduced belt drag, and noise. Idler pulleys keep the belt from slipping during even the toughest 3D maneuvers. Dual 1-way bearings were then added to the aluminum auto hub to remove gear slop and complete the bullet proof drive-train.

With the frame system completed, Beam engineers next moved to improve the main and tail rotor systems. On the Main Rotor system, they went with an all metal Swashplate with adjustable lower Swashplate ring so your Beam would never develop a sloppy feel.

Designers then focused on the flybarless rotor head, where they developed the all metal head to include High-G 3D thrust bearings and dampeners as standard. This was done to eliminate tracking issues, regardless of head speed. While they were at it, they added dual ball bearings to all the mixing levers, bringing the total bearing count to 33.

On to the tail rotor Beam developed an ingenious 1 piece aluminum tail case for reduced weight and ease of maintenance. Add ball bearing metal tail grips with a metal pitch slider and pitch plate, and you have a solid tail for maximized gyro hold. As the final touch, Beam added their virtually unbreakable landing struts to protect your bird from the hardest autos you can throw at it.

No reverse engineering, just forward thinking. At Beam, doing things better is not just a concept, it's a reality. So put away your dinosaur 450 and step up to the innovative Beam E4 V2 advanced. You'll be glad you did.

V2 Advance Improvements:

  • Improved one way sleeve/one way assembly: A 1 piece one way sleeve with the shim at the base of the sleeve makes for an even more precise fit than before!
  • Rear tail servo mounts in frame: This will accommodate a mini and a micro servo, plus also will fit a full sized tail servo mounted on the boom. The idea of having the servo mounted in the main part of the body is the centralized point of balance.
  • Strengthened airframe: Another great part of this new design is the integrated battery tray and additional frame support. It also features slots in the under tray for greater cooling to the rear tail servo.

Beam E4 V2 "Advance" 450 Flybarless Helicopter Kit w/Blades (Orange)
I am not a verified owner of this but I am for the flybar version of the heli (BMH-E4-A-1O) and the flybarless rotor head (BMH-E4-7001) and you can see my verified owner mark on my reviews of those products. I absolutely love every feature about this helicopter. The parts are extremely precise. The blade grips on the head and the tail swivel seamlessly. Aside from the ball links, landing gear mounts and screws which are steel, every single part on this helicopter is either aluminum or carbon fiber. The design is rigid and flawless and easy to work on. I love it.)

The E4 V2 Advance was my first 450 sized build. The description provided here is entirely correct. There is a modest parts count and the heli goes together very easily. The instructions are particularly clear and everything is provided in the kit. The parts are extremely well made with a high degree of refinement and use of quality materials. The design is solid and while others complain about the stock FBL head, I have installed True Blood Engineering head dampensers and I am getting virtually no head slop. I have had my Beam airborne for over two months now and I can happily report that it is terrific. Using MKS servos on cyclics and the tail provides very predictable behavior which is great for newbies like me. My build includes a CC Phoenix ICE 50 which never gets hot and provides additional high-end features (like programmability and governor) for when I progress to 3D flight. I am really thrilled with my Beam E4 and would not hesitate to recommend it to others. And A Main has virtually all of the parts you will ever need in stock virtually all of the time. Thank you A Main for your superior service and for carrying such a superior model.)
