This is my first esk8 build. Please have a look at my parts list to see if there’s anything I am missing:
What I want: I want something that has decent acceleration for my weight (200lb). I want something that can go about 20mph and has good range (10 mi). Don’t really have a lot of steep hills around so I am not worried about losing speed when going uphill. Here’s what I’ve got for a parts list so far - haven’t bought anything but the deck.
9-ply maple 39x10 longboard deck
caliber II 50 degree trucks - are these wide enough for a dual rear drive setup?
90mm flywheels
Dual turnigy aerodrive sk3 6354 motors 260kV - will these fit on my rear truck without modification?
riser pads - maybe get the 1" and file them down to get desired clearance?
DIYE electric skateboard motor mount caliber II truck compatible
Michobby dual vesc 150a w/ canBUS cable - Any experience with this particular setup?
Two 6S 5000mAh 50C battery wired in series for 12S
12mm motor pully and 3 or 4 to 1 gear ratio. Any good retail ones that would work for my setup?
I thought having the dual motor setup would give me some more acceleration and still get higher speeds, am I wrong? Can I go with a bigger dual motor setup with wider trucks?
If I can fit another 6s battery or two on there I will for longer range.
I have a proper helmet already. For the enclosure I will look for one that will fit my needs and if I can’t find one I will vacuum form it out of kydex or make one out of carbon fiber.
You’d be better off paying the extra $17 and getting 2 VESC from diyelectric skateboard. I know those aren’t the most robust VESC, but I’m willing to be bet that they’re a lot better than Mic Hobby, given I’ve never heard of them, and I’m skeptical as to whether they can handle 12s voltage
Also, I’d recommend getting the TB 218mm trucks and @marcmt88 motor mounts. The turnigy 6354’s a little larger than conventional 6354s and with those larger 218mm trucks, you won’t be pressed for space.
Lower the KV of your motor, you’re above the 60000 ERPM (limit for the VESC you’ll use) and although possible, it’s not recommended. With 1:3 gear ratio you could achieve 65km/h which in al honesty, is simply mindbogglingly fast.
First off all, yes the hardware design is vedders, the software is vedders. That esc on the Picture is not made by vedder but by “mic hobby”, quality of which i know 0 about.
Speed depends on more factors then the amount of motors. F.e voltage*kv=rpm of motor(roughly) - > gearing to Wheel-> top rpm of 90mm Wheel → translate to km/h. Its a pretty accurate way of calculating the speed.
My first board was a single motor build with one 6374 on 10s. I shat my pants several times learning to ride Electric with that setup, berly ever pushing it to the speedlimit nor having any problems whatsoever with hills. Later tried dual 6374. The term “action stance” comes to mind when trying to cope with the torque that board gave. no way you’d pull moderate throttle and still be on it if you werent fully ready for it.
Guys, I appreciate your input - you’re truly awesome. You’ve convinced me to do the following:
Start with a single motor 6374 190kV setup
I am still going to go with the 12S battery
Do a 3:1 gear ratio
Spend the extra money on the diyelectric skateboard VESC
Get the wider 218mm trucks
Hit up that dude for the motor mounts
This gets me a good start and plenty of things to play with to get more speed if I even need it. I don’t think I need to be going 30MPH right out of the gate.
If i remember correctly i had 34:14 theeths. roughly 2.4 ratio.
Sudgestion would be to buy one or two of the motor pulley with different amounts of teeths to find just right ratio for you.
Bought the pulleys and belts off http://esk8.de/. Used keggels for Wheels.
I do not want to open a new topic I found this very specific.
I am interested in my first construction of an Elongboard.
some research I chose to set up.
Board - 41’’
Pulleys - 15/36t belt 15mm
Wheels 90mm
