The 7HV is a completely new design. The 700 electric helicopter is equipped with innovative features like an automatic belt tensioner, one battery slide, which made the quick change battery very easy and a thrust bearing, which protects the ball bearings of the drive.

• The helicopter comes fully the Fe by Sebastian Zajonz, which has incorporated many years of experience in the design. This helicopter was waived really anything that is unnecessary. Thus, the 7HV no push / pull linkages and gets along with very few components.
• The single-stage transmission with large diameter and 1.0 module gear is the burden of the strongest growth engines and provides a high efficiency.
• All linkage is linear and all turning points of the swashplate servo-arms be found at the same height. Angle error as are found in other high-value products are therefore excluded. An oblique linkage may simply not result in symmetrical eruptions and the performance of the system is limited.
• With a view to the future, the geometry of the swash plate and rotor head together with the servo arms on the Flybarless use optimized.
• All servos, the speed controller and the engine sitting on the tail boom and the battery is so close to the center of gravity.
• This arrangement ensures a very high center of gravity, which increases the performance, so does the 7HV with less energy to achieve the same maneuverability and facilitate the Flybarless system his work.

FEATURES

• 120° CCPM without push/pull and absolutely straight rods.
• Very strong maingear with 136 modul 1 teeths.
•   Automatic belt tensioner.
• 25mm Tailboom
• two Idlers with normaly no contact helps to hold the belt on the pulley during hard manouvers.
• Nearly every motor will fit on the motormount without any changes on it.
• Tailbelt with 9mm width for the hardest 3D stunts.
• Battery-Tray for easy batterie changing with just one bolt.
• Ddesigned to have a high CG. That means the batterie hang as close as possible to the bearing block and all servo positions are higher than the Tailboom.
• Short 10mm mainshaft for highes resistance against bending.
• 2 Carbon Frame stiffner connect both Bearingblocks to a strong box and make the frame extremly stiff. 
• The frame is designed that the upper part will survive in most cases of crash and the repair is as easy as possible. 
• All servos are mounted within 10min without difficulties.
• 3mm strong sideframes at the tailcase. 
• Stronger FBL Head with spezial rods and strong m4 bolt for highest forces.
• Battery Slide
• Against storage
• Module 1.0 teeth
• Flybarless use optimized
• High center of gravity
