Post your boardās power stats! Iām doing some data collection; all contributions are appreciated!
Hereās what Iām looking for:
qty motors (e.g. 1wd, 2wd, or 4wd)
motor kv (e.g. 205kv)
gear ratio (e.g. 42:17)
wheel diameter (e.g. 150mm)
battery configuration (e.g. 20s4p p42a) Per motor:
battery current max
motor current max
Subjectively, how would you rate this buildās torque (acceleration) on a 1-10 scale? and follow-up question: how many total miles(or kilometers) have you esk8ed? (im going for order of magnitude percision here, so 100s, 1.000s, 10.000s, 1.000.000s, ect. )
If youāre an overachiever, you could also throw in:
when riding, what is your average cruising speed?
motor size and brand (e.g. 6384 reacher v5)
drivetrain type/brand (e.g. apex jump drives)
wheel type (e.g. SRB race slicks)
deck info (bindings? significant drop?)
esc type
any other info about the build
If you have multiple or many builds, feel free to post stats for multiple. The more the better.
If you want to post logs of your hardest rides, go for it, but this is definitely not required.
Logs / a recording would be far better. My 1st board felt crazy to me at the time, but now Iām running 2x the current and I know that doesnāt even come close to other setups Iāve tried
2WD
190kv flipsky 6384 (switching to 179kv reacher 7490 soon)
72:15 (switching to 78:15 20mm wide pulleys soon) on BN Precision XL motor mounts with custom dual idlers
200mm kendas, stretched (possibly switching to 165 Xcell)
13S4P P42A from an ownboard Zeus Pro
Batt current 50A/side
Motor current 100/side (going to bump to 120/side soon) on a ubox v2 75V
Current configuration with the flipsky motors and 200mm wheels has okay torque. Definitely a noticeable step up from prebuilt boards but not a raceboard by any means. 6/10?
the point of this question is to get an answer to the question āhow torquey does it feelā as you might get it if you asked in the beginner question thread. I ask a few other questions intended to give an idea of the riders experience. Id rather get this plus the theoretical capability of the build (through the stats) than get less responses because people donāt want to dig through their files for logs.
Essentially, the point of this question is actually to get a non-objective answer to the question āhow torquey is your board?ā, hence the word subjective. Iām trying to determine the relationship between actual torque and the way people experience it.
Weāre collecting mostly objective data here. Hard to say how hard people are pushing their hardware without logs but all I really care about right now is the capability of the hardware as far as numbers are concerned.
Current set up is
2wd
173kv
2.6 gearing
155mm wheels
18s5p p42a
70amps battery
130amp motor
Build is geared to pull motor amps as I am in the middle of testing my ESCs. A lot of torque even with the high gearing ratio, not as much torque from standstill but once you are at 5-10mph 30 comes very quick!!
i gotchu (old more familiar setup in [])
heavy rounding on the odo conversions just cause thereās a big give or take for unaccounted ride logging
thane [~8000 miles (13000 km) on the odo]
2wd
18s2-4p
190kv 6396?
2.78 ratio BN M1 straight
110mm TB
SC100D
96 -96 motor
96 -96 battery
i forgot throttle settings
acceleration, i lowkey forgot to give details but i think itās a good, 8/10. itās decent but nothing crazy.
mtb [~2200 miles (3000km) on the odo]
4wd
18s2-7p
190kv - BN6355
15:83 jump drive helical [21:82 BN AT straights]
165mm RS
bindings
SC 100D+, SC100D+/Dx, depending on when you ask cause i blew the D+ up lol
53 -53 [69 -69] motor
53 -53 [69 -69] battery
.13 -.13 [.18 -.18] ramp
9 9% [11 11%] throttle ramp
[it had good acceleration, maybe a 7/10. it has great pickup, even better braking, but i can tell itās compensating for lack of torque with power.]
now has oodles of torque, hence my lower power settings. I hace it to where i feel i get just about the same acceleration feel between old and new. new config is about 2 weeks old, but i can tell the acceleration is lower, a 6.9/10. despite the torque, ya, it doesnāt have the punchiness off the line i expected and i can tell it gets off the line slower than my old config. sorta. it pulls like no oneās business and it even has a difference behavior when i lose traction, not much sliding around anymore, more of a kerchunk, very gRrRrRrRrRrRr. i lowered the ramp time but blew my escs before i could try it outā¦
old
fuck you discourse on ios for refusing to upload the new boardās video
efficiencies:
2wd - ~8Wh/km (13Wh/mi)
[4wd] - ~18Wh/km (29Wh/mi)
4wd - ~16-17Wh/km (27Wh/mi)
average temps:
40-50°C esc
40-50°C motor, but i stopped using motor temp.
i ride flat grounds of Indiana and hills of SF/Bay Area,
group rides i attend in SF sit around 28mph moving average
side note:
straight cut gears for life you canāt tell me otherwise
im a little confused here. Is what youre describing as torque the ājoltā at the beginning of acceleration, while āaccelerationā is the sustained acceleration (sorry for circular definition)? If you wanted more acceleration, why did you lower the motor current?
also, have you ever tried one of the SRB inrunner setups? if so, how would you describe the feeling of the start of acceleration of one of those compared to what this is like?
another way to put it is it has way more torque at a given current compared to the old ratio, makes sense, 3.9 to 5.5. but having the same current settings would be quite unridable on 5.5 so i matched the acceleration to how iām used to having it.
but because of the decreased current it doesnāt accelerate as hard even if it has the same amount of torque when conpared to the old board, ya? like pure definition of acceleration, change in velocity
i guess a way to think about it is imagine if youre on a winch and itās about to pull you off the ground, onās a 1:1 ratio abd the other on 3:1
1:1 itād yank you
3:1 itāll kinda just lift you like nothingās changing
