maybe im understanding, but this is where im not following. At a basic level, acceleration (rate of change of speed) is directly related to only 2 things, applied force and the mass of the thing being accelerated. Thats the equation F = M A, which we can rearange to A = F/M. Torque is a rotational force which your wheels convert into a linear (straight line) force which can push you. So if we assume you have the same torque and wheel size (do you have the same wheel size?) , and you have similar mass, acceleration for a given torque should be quite similar.
the physics term for the rate of change of acceleration (speed of acceleration if you will) is ājerkā iirc. I think this is the difference in what youre describing. Not sure on an electronics/mechanical level what is likely causing this tho, so maybe someone can weigh in.
iām thinkin mas as change in velocity over time rather than FMA
like, yeeeee, how i have it gives samish torque between 3.9 and 5.5 but the lowered power setting on 5.5 doesnāt make me go faster, as fast as 3.9 does only looking at just off the line
after that, they feel about the same
like havjng a pickup truck vs a decent sports car, ish

this thing is a tank and brings me much joy
It could use a bit more torque but the top speed is nice so no tradeoffs allowed. Must build new board instead when baby stops stealing my skate times.
It has about 400N of thrust in the low end, 4000W of power at the top end, and a 45mph redline. Curiously, it feels like the thrust increases somewhat up to 25mph, itās not the sensorless transition so Iām not sure why it feels that way.

average speeds are usually around 30km/h when racing short track i think. I managed a 50km/h average the other day when i opened her up through the streets

SRB open gear drive on 3-link trucks

Spintend 75V V2
Board is geared to 55-65km/h depending on track. Torque is decent but not mind blowing. I could do with greater acceleration as I get beat off the line still by lighter riders. Iām about 95kg rider weight. Overall i love this board but still want it faster. 3-links are definitely my favorite trucks for racing.

deck is Ramm offroad deck medium
Geared to 57km/h and plenty of torque. Not as much as the race board (mostly because of larger diameter tyres) but plenty for offroad. Only thing Iād change is run lipo instead to make it lighter for jumping. Itās a tad on the heavy side so i pull up very sore through hips and shins after jumping .
My commuter is pretty juicy too but not worth listing stats really.

1:5 gearing on

Running good old escapes

80A battery and
110A motor per side.
There is never enough torque (so 7/10), but itās a good balance for me between top speed and torque.
Running 1:5.5 at the moment which does lack a bit of top speed with 170kV motors, so 1:5 is still my favorite.
Always a must have is
ramping time of 0.1s and adjusted throttle curve. As minimum with the Hoyt puck. Around 25% is about right for me.
Iād like to compare that one to a HV build one day, but guess not in near future.
@MoeStooge or @fessyfoo i know ive already gotten all the tech spec from you, but id be interested to hear about your torque satisfaction; How would your rate the SRB v5ās (or similar setupās) torque 1-10?
total current max: ~22 amps-30 amps (but probably much lower?)
avg speed: 21 mph - 23 mph if both motors cooperate
basic thane wheels
deck: ultra flat with flex if you weigh a normal weigh, but no flex for me

Also holy shit I was cutting it close with my hub motor last night. Any more use while the washer was broken in half and in it and the winding would have gotten cut through completely
I figure 6/10 for acceleration and torque. Not slow by any means but not crazy either. Settings are conservative so I can put more power through it but I am happy where itās at. Can power up hills no problem
I cruise around 20-25 with bursts Around 30mph. Not higher than that. Gets scary
