High speed (40-50 mph) build! I need advice/help please

Sadly not, I’ve been pretty slack lately with it. I got a real case sorted and then I never really bothered with much more as I need to go down to bunnings to get a few things :slight_smile: I’ll happily organise it at some point for you.

I hit ~30mph all the time on my street carver. It’s seen 35mph maybe 2 dozen times. Nothing ever seemed super sketchy about it. And my trucks are really loose too.

Again, I need to see it to believe it. To date all I have seen is super sketchy handling on those trampa builds. . Don’t get me wrong, they seem great up to 20 mph but it is the last thing I would want to be riding at 35 mph. Definitely wouldn’t recommend it for a speed build.

Haha if I’m comfortable on this at 30+ i guess I should really try a dedicated speed board then huh :stuck_out_tongue:

What’s the setup you are running to reach such a high top speed?

My experience so far with Trampa builds is similar. They arent stable above 25mph. My buddy has a 16ply 4wd and hits 30mph+ regularly but definitely looks wiggly at those speeds.

Pshaw hits those speeds often…and is just fine…me on the other hand. I never wanna ride a trampa again lol

From yesterday going 30+ on the trampa…the wobbs are real on tramps for featherweight riders lol…

Where as in the vanguard I hit those speeds no problem… <3 flex hate stiff decks.

Pretty much this: http://www.electric-skateboard.builders/t/e-toxx-directdrive-vs-trampa-vesc6-vs-leopard-8072-170kv-vs-nowind/30822

Except I’m using a belt setup rather than direct drive

Hi Keivan, I’m also a 17 year old looking to go fast with an electric longboard. I read through literally every reply and comment but I have a hard time understanding what the gear ratios and power supply have to be for the board to go fast and far. I also want to build a board that goes around 40-50 mph. I’m wondering what did you eventually order. What gears, motors, vescs, and power supply. And since this reply is like 20 days late, did you already get the stuff in and build it?

I haven’t gotten the stuff yet because ill get paid mid December, I’m planning on getting the 245kv motor from hobby king, making my own lithium ion battery, 36 inch downhill deck, dual motors, dual VESCS, and dual motor mounts on caliber ii trucks

For gear ratios, I’m not really sure about that, but you can ask someone smarter on this thread than me.

Hope this helps, its cool to see someone else try and go this fast too.

have you ever ridden a normal longboard at 40mph?

Fast seems fun till you get the wobbles at 30.

Hey since you haven’t gotten anything yet, lemme throw some ideas too :wink: You got a nice budget so nice parts is possible (don’t know your location though so prices may vary).

  • About your 2x VESCs, get a DirectFET version (vesc6, FOCBOX or Chaka’s version) ; with the 6 you should not get a problem crossing 60k erpm if I recall (need to confirm this, sorry if this was said before). It is expensive but you can always wait for me and other to report on @stewii hw6.4 offering, about how it performs compared to Trampa’s ones.

  • For batteries, well if you do the pack yourself you can pack a punch for not too big price. Maybe try Samsung 30Q cells because it is a 20A 3000mAh cell with decent voltage sag, despite manufacturer’s rating it performs better and cooler than both 25R and VTC6 or HG2 for example. A ballpark is 150ish € is price for bare 10S4P of 30Q, with group buy you can make it down to 120ish. 10s4p is ~450wh, that’s very conservative 20-25km street use.

  • About trucks, I recall somebody here praising Ronin trucks. Miles better than Caliber trucks was what he said.

  • I’m sold on direct drives and hub motors. Or Jenso style drive. Look at @BigBoyToys 4wd setup, the beast is fast!

  • @psychotiller makes sick enclosures for electronics.

It’s not your first e-board so I’ll keep it short to these suggestions, but 1000usd should allow for a nice setup damn !

This "going fast " is like buying sports car we want the fastest out there but soon to realize this is to much and just cruise and never go fast. You have yet to actually go 30 or even 40 .Also it’s going to be hard to hit 40and up with nonhub and direct drives

Id say this is generally true but my 4wd Carvon breaks 40mph, acceletates well and is the most efficient board I have. Cant say anything negative about it besides it was expensive to build lol.

My advice for you is to save up some money for the doctors before you go out and ride this thing

Surprisingly yes. Me and my friends are a bit crazy. They would drag me behind their car going 50 mph down a smooth road on a regular non-electric longboard.

sounds like you need new friends :joy:

Lmao. But I kind of get used to the speed wobbles and learned how to control them
