COMPASS
ATOM 7HV Ultimate
The 7HV is a completely
new design. This 700 electric helicopter is equipped with innovative features
like an automatic belt tensioner, sliding battery tray, which make the quick
change of batteries very easy, and a thrust bearing, which protects the ball bearings
of the drive.
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 movement. Angle-error and uneven
movement 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.
