Lumenier RB2204 2500kv Full Results  [CLICK HERE]

  

This is the luxury "Skitzo" motor from Lumenier.  A friendly conributor sent it in for testing, and I've had a ton of requests for it, so without further ado...

This is the 3rd lumenier motor to hit my bench, and I still have two more that will be coming in the 1806 shootout I'll be starting soon.  As with the other Lumeniers, build quality and machining is excellent.  Bearings are super smooth and windings are tight and neat, though of smaller guage wire than many of the other motors on the bench.  The air gap is a bit wider than I typically see and that shows in the results as well.  The most striking thing about this motor is the weight.  At only 22g it rivals the SunnySky X2204 2300kv for the lightest 22XX motor, only weighing in only one gram more.  The weight here I think plays a really cirtical role in the evaluation of this motor. More on that below.

Results

The results here were somewhat interesting.  This is definitely not a "power" motor.  It runs extremely smooth on the stand.  As with the 2204 2300kv variant, the thrust and RPMs were a bit disappointing, but that is mostly by comparison to the modern 2205 motors.  Taken as a light weight 2204 motor, the results are much more acceptible, and the motor merely sips current, instead of drinking from the fire hose like the 2205 and 2206 motors.  Given it's weight, I think this motor really shines on 4" props, and being 2204 the mid range 4" props like the 4x4x3 really do well, hitting almost 800g of thrust at only 18A.  The 5" props didn't fare quite as well, drawing almost 25A for not quite 1kg of thrust.  Again, though taking the light weight of this motor into account, this motor will do quite well on an extremely light build with 850mah or 1000mah 4S batteries.  I suspect an AUW of less than 450g without an HD camera would be quite feasible with these on the right frame. The 5x4 prop may be the best choice for that configuration, provoding over 930g of thrust at signifcantly less draw (just over 21A), though given the right battery, 5x4x3 is still feasible.
