A little bit about myself, I come from a Robotics background, majoring in Programming and design (with a fair amount of build experience). I just recently lost my job (New management) and have been feeling down, so this project is a pick me up . For reference I’m fairly small, five eight and weight around 150lb.
Breakdown: Chain driven electric longboard with an 11in go kart wheel as my rear wheel (yes a single) and normal longboard wheels (with shocks) as my front,
The mounting frame for the wheel and the motor I will be custom making out of some aluminum stock I have lying around.
So here are the specs:
-1x 11.5 x 6.0-6 Dunlop slicks ($30 off eBay) -2x 190Kv 3150w 6374 DIY motor -2x Multistar 6s 20Ah Lipo battery pack -2x HK Beast series 150A esc -The front trucks are currently cheepo trucks from my old longboard, gonna get an MB truck with inbuilt shocks. Probably along the lines of this -If you guys are curious I am custom building the remote (one of my duties in my old job), having a friend of mine 3d print some prototypes rn.
The gearing will be 1:5 (12t: 60t). The chain will be #35 (mainly because I already have the chain as well as the 12t sprockets for said chain )
*I should mention I am mounting the motors on either side of the wheel and chaining them individually to their own 60tooth sprocket on the wheel. This is for easy expandability later on if I want to add on 2 more motors for MOAR TORQUE!!!
If you guys want I can post more details on how the wheel assembly is going together in the comments, but essentially imagine a go cart wheel assembly on the back of a longboard (When I was in high school I spent a summer servicing Go karts at my local Playdium)
The only parts that are currently locked in are the wheels, sprockets, and chain as I already have those from previous projects/work assignments.
So here is what I am looking for: Are there any choices I made which I could get a better value else where? (Ex, I’m bounding between the DIY and the SK3 6374 motors, the difference being the DIY has a 3mm keyway, for which I have keys for)
What would you guys estimate my top speed, as well as my range to be? (I know use the calc.it for the top speed, but I want an experienced builder to give me an estimate, plus it can’t do range(I have some rough numbers for range based on my experience, but that’s from a completely different feild))
Will I have crappy acceleration because I am going to an 11in wheel rather than the standard longboard trucks or MB 8in wheels?(If so I am open to suggestions)
Should I go with 2 168Kv sk3’s instead?
Also ESC vs VESC for my application, what are the suggestions?
Any battery suggestions? (will mine do, am I missing something here?)
Also, I’m all ears on suggestions for enclosures, I was known for shitty wire management and I can tell you, what I make generally works, I give it to the rest of my team to make it look pretty
I have a bunch of sketches to clear up some details if you guys want I can post them later on. Seriously, like 40 pages worth (Old habits die hard I guess).
That’s all, any help would be appreciated. (I will be ordering parts in early August and hopefully completing the build in early September)
