Multistar V-Spec Outrunners are designed to maximize performance! Setting new standards in multi-rotor performance, each Multistar V-Spec motor is purpose designed for a specific application allowing for efficiency and power to be optimized for the intended use.
Far from being just a pretty face, Multistar V-Spec motors are built using the highest quality components and manufacturing methods; Japan bearings, N45SH magnets, .2mm laminations, 180deg oxygen free copper wire, 0.005g balancing tolerance, precision windings and rigorous post production inspection to ensure that only motors fully matching the specifications are made available for sale.
The Multistar V-Spec 1304-3100kv is a real little gem of a motor designed for the mini range of multi-rotors and optimized for 5-inch props, perfect for those tighter frames where 5 inch props is the maximum.
Multistar V-Spec raises the bar with its outstanding quality and performance.

I can only give 3 stars across board for not including motor mounting bolts of any kind,
mounting bolts cost a fraction of a penny/cents to include, even if they are too short or too long; we don't have a problem seeking out bolts to suit our needs and store the ones supplied for another project! but to supply Nothing is begging a Negative so I have given 3 stars even before getting to mount the motor. RThis little thing is Awesome! I used it to power a HobbyKing Ridge Ryder using a Turning plush 10A esc, and 0.8mah 2s.these motors are great the only reason i am giving them a 3 star is because of miss shipment and 2 broken motors out of 12I bought these for the size. Got them in and found there are no adapters for the 2mm shaft to the 5mm hubs for propeller. If you get these, plan on making your own adapters.I'm a little bit surprised that these motors are still so unknown and without any review here.
I'm following like so many the new trend of 1306 motors with only 3-3,5 inch props and full FPV stuff for AUW around 200g. I was looking for some lighter alternatives than 1306 but bigger/more powerful than 1104/1105 (which are great but not enough for 200g AUW).
And these 1304 fit perfectly in the gap between 110x and 1306 motors. Weight without nut (where I always use lighter and better stop nuts) is only 7,7g which ist around 4g less than usual 1306, so saves about 16g overall which is a lot for micro quads.
Thrust with 3-4 inch is similar as with 1306 but keep in mind that these 4g less means 1/3 less metal to cool down high currents! So 4S 4" may be to much or 5" 3S.
I personally would not use this motor for 5". They are great with the pricy Rotorx RX3040T or with Gemfam 3545BN GF/Nylon reinforced.
More kV would be nice as many people will use this motor only for 3-4 inch.
Sound/smoothness is fine so far, let's add some more test flights to give 5 Stars quality.
Motor cables are like most 1306 so-so and easy to break at the ESC soldering. So still room for improvement. The only small motors I know which do much better here with soft cables and multiple fine wires are RCX (even until 1105 size) and DYS 1306.
