Did the testing today, now rainpocalypse has a day off.
General impressions-

Fairly good quality

Longer than usual 130's as they are an intermediate size, you need to trim the tags in the motor well off.

LOUD

Too hot, revving at much higher than Rhinos, waste a lot of power in producing clouds of foam dust

Might make good pushers

DATA is here.

I will get these to SSGT for data sheet tests etc so we can add them.

Would be a little more interesting to see them used with a higher crush flywheel as you would be putting more of that speed to use. Not saying they are ideal but considering the manufacturer has redesigned the cage and wheels I would assume the motors are made for that application. There really is a demand for a proper 130 2s flywheel option, not everyone want to cut holes in their blaster. It will bring balance to the force Very Happy

Possibly but more crush means a greater load which means you need more torque (or at least a motor that can maintain a high enough speed when it's loaded enough to produce that torque) and with motors you usually increase speed at a given voltage at the expense of reducing torque and/or increasing current draw (although, granted, this slightly larger-than-130 form factor should mean it can produce more torque than a comparable, i.e. 50kRPM, 2S 130 motor). It's possible that they've overdone the speed to try and make up for a lack of torque i.e. the speed may drop right down under load with higher crush flywheels/cages but will still be high enough to achieve "glass ceiling" velocities for that setup (a pair of motors that can maintain 30kRPM under the load imposed on them by the required flywheels/cage should be capable of velocities of over 170fps). 50,000RPM is a lot though - unless it drops all the way down to 30-35kRPM under that load, I think they'll still be too fast even for Artifact flywheels. If that's the case then it's a similar way of thinking as using a higher voltage supply to get around higher resistance wiring/cells which is similarly less than ideal and pretty poor from an engineering perspective. When darts first enter the flywheels they'll be spinning close to their no-load speed of 50kRPM which will likely result in quite a bit of additional wear as well as noise when revved but not firing.

I don't know enough about the Chinese Nerf scene to say for sure but's it's also possible that they're more into their multi-stage flywheel systems over there and they've kept that in mind when speccing these motors. Like I've said before, if they do produce enough torque I feel that this might be a very good application for them.

I think they just take the "more noise = more power" approach to tuning. Any motor that has adequate torque will pull more FPS at the same crush. To put the performance of these into context, Black Pigs hit
114fps average in that exact same blaster, Meishels shot 112  and I shot 118fps average on 3240's in a RS. A motor that is too hot will always be too hot, similarly a motor lacking in torque will still lack torque, regardless of the crush. These may have been designed for higher crush serrated wheels, where you could achieve better results out of them at the expense of total dart destruction.
I would argue the same results could be achieved by better specified motors with smooth wheels WITHOUT destroying every dart that goes through the wheels because the motors are revving high simply because the designer doesn't know enough about flywheel mechanics.
I will test all the available flywheels with 3240 motors, as they are very consistent quality.
Complaining that a comparative test procedure isn't fair because I didn't use a pile of exotic and currently unavailable extra parts to maximise the motor performance doesn't enhance their reputation.
This forum works on fairly gathered, carefully presented data.
The test process for these was no different to any others, the blaster was the same, the pack was the same, I used matched wheels, within 0.4g of the original set, I ran them in to ensure even foam build up and used the same chrono and brand new Elite darts. I shot a large sample and discarded the highest and lowest result, then compared the average. I took a shit ton more care over cage assembly than anyone else, it's wheels are +/- 0.05g of each other and centred to +/- 0.1mm in the cage.
Any flaws in the results are down to the product. If you don't like the test process then don't rely on our data. If that's the case you can be sure I will seek out the parts in question and test them anyway because there are lots of very poor performance claims still out there and I for one will always act in the interests of modders getting the best performing part regardless of marketing fluff.
