Hyperion

Z4025-368

Z4025 is a medium size outrunner, 40mm stator diameter with a very nice and exlusive design, 3 ball berings is the one feature that sets it apart from most of the other outrunners on the market. The large ball bering supports the rotating bell, this fully supports the bell in both front and back of the motor, this makes the motor go smoth with no osilation or vibration even on high rpm, in some cases this type of design can increase the efficiency up to +- 4% specialy under load, this also reduces magnet and ball bearing faliure, and keeps the motor run smoth when driving big props tru aerobatic rutine.

Z4025-16 can easly match the power of a 70 size 4 stroke motor, with a maximum recommended power of 1300watts, i think that this motor in burst can be pushed more for 5-10 sec. In quality and design this motor can be compared to the very nice Plettenberg Orbit and Kontronik Kora motors, this is the best in quality, performance and design i have seen in a motor made outside of Germany. This motor outperformes the Axis or almost any motor produced outside Germany on the market.

To the right the Z4025 laying beside the actro 24, this motor can be compared to the 24-6, two very good motors but the actro have higher efficiency and higher power level, but its also more expensive, otherwise they are very simular in performance and size.

Data Z4025-16

Z4025 proved in tests that it has very good self cooling, pic above shows the cooling holes in both front, back and casing.

Motor have been puched up to 1300watt 12000 rpm witout any heat or vibration problem, trotteling with the Jeti advance controller is realy fast with smoth start up, the Titan 80A controller gives same rpm and amp but has slower trotteling response, best setups on the se controllers is Jeti: hard timing, Titan: hard timing, soft start.

The Jeti advance controller works good on any outrunner i have tested with, setups up to 4000w, they always give me smoth start up and fast trotteling, driven the motor efficient, this is the first time i found a controller that almost match the Jeti advance, on Hyperion motors the Hyperion controllers perform very good, programing tru the E-meter is also a nice feture, i will continue to test the Hyperion ESC on other outrunners and see how they perform.

Comparing performance on Z4025, Jeti VS Titan

16x8"CAM Hyperion 80A 19,35v 31,8A 6300rpm 615,3w 10,2rpm/w

16x8"CAM Jeti advance 19,06v 33A 6330rpm 628,9w 10rpm/w

Stator have high copper fill.

Motor nice desig and put togheter with high quality parts, this is the best i have seen in quality on a motor that are produced outside Germany. Stator has god copper fill, there is no rust or damage on the stator as i often notice on motors when taken them apart, high quality Japan NMB ball berings, stator plates done by CNC, rounded magnets and balanced casing.

The one big downside of the Hyperion motors are that there is no efficiency data avalibul from the manufactor, one could ask why!?!? Nice motors as the Hyperion should have efficiency graphs from Dyno tests, so one could setup the perfect powersystem for the motor. Lets hope we get this in future. Maxim efficiency of this motor i think is araound 85%, the good thing is that it doasent drop very much in efficiency when starting to push it.

With the motor and Hyperion controller i have also tested the 16c Hyperion Lipo 5s2p 4200mAh battery, 16c continuos and 20c burst power gives this motor high power to weight, on 5-6s setup it can easely drive a large and efficient 18" prop that fitts good on slower type of aerobatic/3D modells. On 53Amp load the Hyperion 5s2p Lipo holds 3,47v/cell with no danger in heat, battery are but togheter nicely with simular quality as the Polyquest battery packs.
