Immediately when we saw this we said wait a minute, why have they released two motors of identical stator size and kV….
Until we found out there is one key difference. The Skitzo variant of the motor, the RB2205C 2400kV, uses ceramic bearings. These are said to be much smoother than the classic metal bearings currently used in all our motors. However they have a much shorter life span, crucially because they are much more effected by dirt entering the bearing then metal bearings. We think this could be a huge issue on a miniquad, as we crash almost 24/7, often in mud or sand, which can easily enter a bearing. Indeed they also cost a whopping $35, making them one of the most expensive motors we have seen yet.
That being said we expect the quality of these motors to be top notch, like any other Lumenier motor, and they are light, really light. They weigh in at only 24g! This is by far the lightest 2205 we have seen yet, and an decrease of 6g over an Emax RS2205. This will make a huge difference to the manoeuvrability of the quad as the moment of inertia will decrease significantly. They also look damn good, especially the Skitzo version.
We have yet to know what magnet is being used in the motor, but we hope its the N52SH or the N52 at the very least, given the price point.
The new Lumenier 2400kv RX2205 and RB2205C “Skitzo” limited edition motors fill a gap in Lumenier’s multi-rotor motor lineup, by hitting the sweetspot of power and weight.
With a 2400kv rating and 2205 stator size the new RX and RB 2205 slot in perfectly between the Lumenier RX2204 and RX2206 motors, some of the most popular drone racing and FPV freestyle motors on the market. With this new 2205, Lumenier now offers very granular motor choices from 2204, 2205, and 2206 across various kv ratings providing you great choice when specifying your build components. The new 2205 motors come in at sub 24g continuing Lumenier’s tradition of creating some of the lightest racing motors on the market.
They go on to state
Carefully assembled and dynamically balanced in Lumenier’s climate controlled facility, the new Lumenier 2205 motors deploy new glue technology, application robots for even glue distribution, and advanced curing procedures to ensure magnets won’t slip — even under the tremendous demands put on them during drone racing and FPV freestyle events.
