So I love the performance of these motors but I wouldn't ever put them on another freestyle rig! I've owned 4 sets now and all the bells have been completely ruined... can't even hit tree branches without these things seizing up! The 17$ velox motors from tmotor have much better bells for cheaper.

Change the bell design and ill come back later but these things are flimsy asf

Great motors. Fun to play with. Love how they respond to my stick inputs. Motors aren't boring, they feel great, but they can't take a hit for S@#!. The image will show 4 from the first batch. They've seen air 3 times. The 3 in the front are from the replacements, starting on the left. Sand chewed up the magnets, they grind. 2nd one got T-bone by a buttterfly, magnets destoryed. The last one got Covid 19 and it just died. The magnet looks like it developed cancer progressed to stage 4 and died. Great motors but they can't take a hit.

I got two 5" quads (Armattan Badger and Marmotte), both were running excellent on T-Motor F60 Pro IV 1750kv (6s). Replaced motors with the FPV Cycle 1880kv, have set the recommended ESC settings (demag/timing/rampup power as per FPV Cycle web site). They fly great, throttle control and resolution is excellent, so much power especially at low end, flying them is lots of fun, makes you feel confident TILL you get a desync, half desync and/or random wobbles/twitches during complex maneuvers like yaw-roll-flip which makes them unreliable and worthless especially if you fly bando and trying to hit a gap through the roof or flying miles away over mountains or over the water... Also I can hear something similar to bearing noise on a new motor!
Nice but raw unfinished product. Sorry.

This finish looks AMAzing. And... I quite like the fading on the logo, actually.

REVIEW FOR LEGACY MOTORS:

Really they are 4 star motors, but 5 star considering I got them heavily discounted. The idea behind the motors is excellent, sadly the old versions have desyncing issues. I was able to stop the dsyncs with the following ESC Settings, the posted recommended settings flew like hot trash.

Rampup/startup power: 0.1 (10%)
Timing: 23degrees
pwm: 48khz
dmag: high

I have my dterm filtering pretty conservative, 1.2 on the slider. I also have to keep my d gains around or under 40, if I go past this, I get micro dsyncs/arm dips.

Once you get them working, they fly FANTASTIC. I am a weight snob, but a Prototype frame with 5.2" props you can barely feel a hero 9. normally i fly a session on 2306 motors because i hate the weight.

Super excited to see what the updated motors bring, cant help but think the new motors should have a new name to distance themselves from the old ones. Not using "Crowns" as a name is a missed opportunity, I feel.

I guess waiting for the new bells because those ones are so fragile and produce weird problems with esc

Crank your blheli startup power up between .80 and 1.00. Stephanie Lujan Martinez says these motors are THE DREAM. No need to aspire anymore, just drop a Benjamin to live it.

After watching a few youtube videos about the extensive motor research Kabab has done, I was pretty confident that these would be good motors. During maiden, I was pleasantly surprised that they were much much better than I expected. Control throughout the throttle range and Power is unmatched. So smooth and so powerful. They're also some of the best looking motors I've ever owned. Don't hesitate. If you're looking for premium motor of unmatched performance, this is the one. I'm changing all my 5" motors to Imperials & Emeralds. Two down, two to go!

Great smooth motors! But disappointed FPVCYCLE didn’t offer a higher KV variant like 1950 kv. They should offer three KV’s 1750, 1870, and 1950kv. Did a 6” build and the motors can’t accelerate the props as fast as I would like. 1950KV!!!

Simply amazing motors! So smooth and powerful. I got the 2150kv version and used a motor output limit to bring them down to 1960kv, which is my comfort zone. These motors are the best of the best!
