MaxiR high end 3D microheli:
LaHeli company
developed the MaxiR after the Rambo in version two (V2)
was released for production. With the experience of the
previous designs, they developed a new larger main
blades for rotor of 62 cm (24.4") and made the required
changes to the overall geometry. The frame was totally
redesigned to a version with side plates and screws
instead of glued parts.
MaxiR is a
micro helicopter without compromise. Cheap DC motors were
abandoned. The frame is optimized for use of an AXI
motors in the 2208 series. It was also decided
that the use of 3 Lithium-Polymer cells was the best,
though battery holder designed accordingly.
Flying capabilities of
the MaxiR are unique. Slim blades with relatively heavy
internal weights, in combination with lightweight
paddles make the MaxiR to be the most stable helicopter
of its class, but with no impact to ability to make fast
3D manoeuvres when flying aerobatics. The performance of
the AXI motor is higher than most batteries are able to
handle (the in-flight performance is limited by the
battery). With actual LiPo cells we can compare the
Maxir's dynamic to aerobatic machines of the 60 class.
Aerobatic
manoeuvrability allows unlimited 3D flying including
dynamic changes between "normal" and "inverted" position
at zero head speed. The rolls can be made at a rate of
360° per second continuously. Flying backwards and
sidewards are limited only by the capability of the gyro
to keep the tail aligned.
Concerning the
repair/service work, most of it can be made without any
glue, all usual serviceable joints are screwed. All
parts, which can be broken at a "standard" crash can be
replaced within 15 minutes.
We consider the MaxiR
to be the top end microsized helicopter. |
