Interesting. how would this compare with the Slot Machine? Would also be interesting to see/hear reports from the track. I'm running a Reedy S+Plus which I'm pretty happy with, and in spite of being older tech gets up in the revs (3571kV @ 3.7A w 46 degrees)
I use to run the Fantom Icon V2 in my B6 because I liked it better than the Xfactor. I am not sure about the 17.5T Slot Machine. As far as the 21.5T... The Helix yields more Kv and speed in a similar distance than the Slot Machine in my TC. I did compare the old Icon to the new Helix and the HW G4 yesterday. I will put all of the motors on the analyzer to confirm the timing and amps I was running each motor. I also have to select the clips with the times per laps. Both were better than my old Icon. It could be that the Icon is old. But the Helix did register more Kv at similar timing and amps based on the data I have from when the Icon was new. I will try to have it ready within a week.
You really need to use a power supply at the same voltage to test these motors. At 4 minutes when using 7.6 the chart shows almost identical numbers to the older version fantom vs new! But then you decide t o use 8.2 volts? Then the numbers are way off. There is no use in comparing motors at different voltage.
I agree that consistency in method is best. I use to think the same way. Then I would have to make use temp, humidity, etc. is the same, and I just don't have the facility. Back to volts... I tested the Helix motors and the Kv is so similar regardless of voltage that I stopped worrying because the issue it the instrument as Kv is a constant. There was a motor where the lower the V the Kv would rise, and vise versa (might have been Trinity). But not the Helix.
Air , humidity? Really? The DC power voltage is everything. The higher the voltage the more efficient the motor is. That effects timing vs amp draw and kv. Your numbers prove it.
@@jasonswint8297 I should have been more detailed. air, humidity, temperature, etc. are all factors. Materials expand and contract with temperature for example. I am not saying they are significant at all. But if I wanted the most reliable test, I would have to control all variables possible variables. Back to voltage... yes, higher voltage yields more efficiency... why we went from 6V to 12V systems in cars, and we should consider 36V in cars... and why 220-240V is better than 110-120V for many large appliances... and why the Cybertruck uses thinner wire than previous EV models due to the Cybertruck's higher V. The point is Kv is support to be a constant and not a variable of voltage. Therefore, in theory, it should not matter what the V is as Kv should be a constant. When I tested a motor there was variation that seemed to point at lower voltage --> higher Kv. But testing a different one, this did not hold. So, I just test to get an approximate result. Now... HW G4 is ROAR approved if I am not mistaken, the Helix is about to or just got approved... the Trinity Slot Machine was dropped from the ROAR list not long ago for changing the design after submitting designs for approval... and will be replaced it with the Slot Machine 2 if I am not mistaken. The HW and Helix are the best of the bunch I have run and one would be splitting hairs. So, I would go with either of the two... HW g4 or Helix. If the entirety of your comments are to "prove" to me that I should get a power supply to run more accurate test... Thank you, you are not the first to suggest it. I understand why... I just do not think it matter as much as I am testing for Kv which is a constant. Keep in mind that even dynamometers have variances. We can always talk about my experience running these motors. I think I have answered why I do not worry about using a constant V. But feel free to give me more details just in case I misunderstood your points. 🙂

Very nice motor what car do u run this in. TY for sharing and doing what u do
I currently have this in my 2wd buggy.
Very good! Is this team/spec or works edition?
Sorry, it is actually a Team Edition.
Curious what the difference is on the works version.
