Compass Atom 7HV 90sized FBL Electric Analysis...
A review of the Compass 7HV FBL 90sized Electric German Graded Model. Admire the beauty of this beast even while in assemblies!
As in specifications at local as well as overseas http://www.skyhobbies.com.sg/Electri...rs_Atom7HV.htm
■The helicopter has been designed by Sebastian Zajonz, who incorporated many years of experience in the design. This design avoids unnecessary complexity. Thus, the 7HV no push / pull servo linkages, and it has a relatively low parts count.
■The single-stage transmission with large diameter and 1.0 module gear takes the punishment of the strongest motors and provides an efficient transmission.
■Direct servo-to-swash linkages are equal length and have linear movements. Angle-Error and uneven movements found on many other products can limit performance, and is therefore eliminated.
■With the future in mind, the Swash Plate and Rotor Head geometry was optimized for flybarless.
■All servos, the speed controller and the motor have been placed at the height of the tail boom and the battery is very close to center of gravity.
This arrangement ensures a very high center of gravity, which increases the performance, so the 7HV can achieve efficient maneuverability and utilize the flybarless systems fully, yielding great results.
■Length: 1372mm
■Height: 403mm
■Rotor Diameter: 1560mm
■Motor Pinion: 13T
■Gear Ratio: 13T: 10.46:1:4.8
■Take Off Weight: ca. 4.3 - 5.1kg
■Motor Type: Brushless Outrunner
■Battery Size: LiPo 12S (2 x 6S) 4000-6000mAh
■Rotor Blade Size: 690-710mm
■Automatic Belt Tensioner
■Sliding Battery Tray
■Mod 1.0 Gears
■Optimized for flybarless
■High center of gravity
