Hyperion have recently released a new
range of outrunner motors, the Z-40
series. They have a 45mm diameter
stator, and is available in 3 different
lengths 25mm, 35mm and 45mm.
The magnets are specially made for
these motors and are curved on both
bell and stator sides. This maximises
heat transfer and improves the
magnetic flux.
They also feature shielded stainless
bearings. The motors also feature a large
ring bearing at the at the front of the
motor to prevent deformation of the bell
at high rpm. The motors can be back
mounted directly to a bulkhead or via the
mounting kit. They can also be mounted
using the rigid front mount, which can
be adjusted over a wide range of lengths.

A typical application is a 1/4 scale Ryan STA, 82” span, Hyperion Z4045-10 with
Hyperion Titan-90HV and 8S Hyperion 3700mAh 20C LiPo and APC 16” x 8” thin
electric propeller. This gives a flying weight of 12 lb. 4 oz. and draws 56A static
current at 27.9v, giving 1560W and 5790 rpm. After flight the calculated average
current was under 35A, motor was 51°C, the battery 36°C and controller 38°C.
The Hyperion Z-40 motors and back mounts are available online from Robotbirds
