Direct Drives???

couple things
frist go xenith rather then unity

also the batteries arent great
there are builders here who will build better for cheaper
assuming your in the usa @BenjaminF or @Skyart or @ZachTetra can build great batteries

remote is fine

direct drives are ok but not super powerful or anything
shameless plug that i am selling some direct drives and you can pm me if you are interested

3d printing an enclosure can work but be careful as they arent always so strong
the deck is fine but short and flexy so you need a split enclosure

first of all, welcome.

now here are a few things to keep in mind:

  • add ur location to ur profile so people can help u better, yes u said u r in London, but not many people read everthing (also, there are 29 places called London lol)
  • carbon fibre can block radio signal. receiver inside a carbon fibre enclosure isn’t a good choice unless u plan to have antenna sticking out to help with the faraday cage effect
  • boundmotor is said to be relate to known scammer, maybe u wanna reconsider? not sure if esk8supply is still around, haven’t seen them active in awhile
  • don’t get the unity, go for Xenith : BKB Xenith - VESC Based Motor Controller (High Power) – Build Kit Boards
  • im sure Apex will do a good job if they agree to build the battery to spec for u

damn, that’s a lot of words, and those are just my 2c

he is on the other forum

from my post above if you are in the uk then @ApexBoards or @tinp123 or @acido can all build amazing batteries

@ApexBoards sell the xenith

and im local to london to (yay) happy to help in any way possible

Yeah I saw his YouTube video where his replies to comments were a tad nasty and defensive. The ones you mentioned look really good and simple to use. Thank you!!!

Thank you Frame, can’t believe how many people have replied already! :grinning_face_with_smiling_eyes:.

Updated profile location :call_me_hand:t2:

That really sucks about the carbon fibre, ugh. Would it still be fine if I applied the carbon fibre to the deck and enclosure, but cut out a rectangle where the enclosure sits underneath the deck so the signal would just pass through the wooden deck?

I”ll stay clear of Boundmotor then. Such a shame because lots of them seem so good to newcomers like me :(.

Just forget about carbon fibre. It looks pretty, but it conducts electricity and is opaque to radio. Use fiberglass instead.

Again, fiberglass. Completely forget carbon fiber exists.

I’d recommend you make the enclosure so that instead of bolting to the deck along its perimeter, just hang it from two bolts on the front and two bolts on the back. Put butyl tape (bubble gum consistency) all around the top edge, inside the bolt holes and lay a sheet of flat rubber on top. Put a cutting board on top of the rubber with some weight on top for an hour to squeeze the butyl tape, then bolt to the deck. This way, you have completely sealed from water ingress. It doesn’t even matter if the top of the enclosure is flat and the deck is concave, the tiny gap makes no difference this way.

So you have like a “tub” hanging off the bottom of the shortboard whose only hole is a charge port, and you’ve sealed the backside of that. No other holes, you should be able to toss that in a lake if you want to.

I would skip direct drive entirely and go for belt or gear or chain drive, collectively called “satellite motors”.

Direct drive aren’t very servicable and the motors are too close to the ground, and you can’t get those nice high-torque gear ratios that maximise range and fun.

I would definitely not buy anything from Boundmotor or eskating dot eu. The second one I have personal experience with, and is terrible. The first one is run by Jedboards. Look them up.

The sooner you forget about carbon fiber, the happier you will be.

It conducts electricity, it blocks radio, and fiberglass is better for esk8 building in almost every way except “cool factor” and “looks”.

sure, it might work that way, but fibreglass is still the way to go. if u really like the looks of carbon fibre, u can slap on those fake carbon fibre car vinyl, they don’t cost that much if u need to wrap a shortboard

we used to have elofty, but it has also disappeared. do u have to use DD tho? belt / gear drive are also pretty good.

Don’t buy @esk8supply ESCs, they are sold illegally and as such are illegal to resell, and your support is worse.

The problem with belt drives is that they take up lots of room that I’m hoping can instead be filled with batteries. Plus I thought DD motors held up better to water? On the clearance and performance side, it’s only going to be a city board so shouldn’t go through any tough terrain plus it’s not a performance board so I don’t need screaming motors. A little more powerful than my current exway Wave motors (max power 1000 watts) is just fine for me :relaxed:

Yes, I know. I thought the same thing.

After many tries though, I’m just gonna have to recommend you skip over direct drive. But do what you want :smiley: They just aren’t as good as they seem on paper.

All BLDC motors will be mostly waterproof out of the box, as long as you don’t use sensors. Water will shorten the bearing life but you can change the bearings. Motor hall sensors seem really prone to failure for some reason, and if you haven’t personally went in there and waterproofed them yourself, then there’s little chance they’ll last very long. Even so, way more reliable to simply not use them at all. Only connect the 3 big phase wires.
