you should get it ! this thing is just awesome. The trampa deck is outstanding.

just did this for you when I saw your message this morning. 4200mAH is 19.60km distance with Multistar cheap 10C. Works fine. 8°C outside. Max Amps draw is 17Ah on 12S

This is "Le palais de tokyo", not that nice for filming.

I think I underestimated range that I'll get out of my two 10Ah swappable battery packs with my build (I thought that about 20 km per one battery pack) :D It's gonna be awesome! (still waiting for the parts :cry:)
As always, great video and editing okp, go-pro gimball is super usefull!

Tires are inflated at 60PSI. Awesome speed. Rock solid and still huge fun to ride.

Image

Image

Image

Multistar 10 are performing quite OK at this time. I will report back often. I remember when I had weak lipos in RC helicopters, sometimes I had less punch. What is difficult to measure here is the punch as 12S on a EMTB... even on a weak lipo... is enough punch to climb a hill ! Imagine on the asphalt.

I drew 5000mAH.. lipo was 3.11V; I had no more power on the batteries; Still trying to push on the throttle; no power at all. But that was normal :)

BEFORE CHARGING

Lipo 1

Image

Lipo 2
Image

Image


AFTER CHARGING


5000mAH over 5200mAH with max capacity charging set to 95% ...with a startup boost value set at 0.030 on VESC (awesome value)

Image
Image

Enjoy!

Now i'm convinced that CF is the way to go. The foam you use is polyurethane?, and does the enclosure act as a faraday cage and block the radio signal?

Nice work :) I decided to stick with UK boxes, they're waterproof and in my opinion it's great feauture in electric mountainboard. I'm still waiting for my new lathe to arrive, then when I find time I'll get to work and finish this project. In the meantime I'll be jelous about Your finished trampa project :D

@Pedro, no signal blocking as the antenna is just getting out 2 cm of the box
@Squad, thanks !

really nice! if you are bored you should make a tutorial on your cfk vacuum skills! vacuuming really allows much sharper and well defined structures, love it!

Very nicely done okp, particularly like the enclosure for the VESCs. So neat and clean.

thank you. I can't recommend trampa board enough. I really like how the deck behaves plus the titanium trucks are awesome in behavior. I wish I could get my hand on a XCARVE; I know people say it's not that accurate or well it's a low cost CNC carver.. but well that would fit my requirements :D

Nice work my friend.
Your carbon skillz are pretty well!

You going straight forward to make the board more lightweight.

Can you confirm that your Multistar Lipos have around 640gramm per 6S-5200mAh Pack as Hobbyking listed?

I´m really trying to lower my boardweight too, build up a new Chaindriven one at the moment.
Using 5800maH ZippyCompact as 12S Config, but i´m still @ 12.5KG.

Ok if i to some rework on the Battery and Electronic Enclosures in a similar way as you do, what can i save? Maybe 600gramms ?!

I´m wondering how you get this low with 11.2KG, maybe i have to weight the Heelstraps, dont know what they have.

Less weight more power (-;

Keep on with your great build.
hang loose

Such a beautiful build. I need to progress to eMTB.

What range are you getting on battery/controller/motor setup?
Surly Ogre rigid 29er, rear 10T MAC @ 50V 25AH & 40A: 30mph road/gravel/hill machine
42" dual diagonal Eskateboard @6s & 90mm wheels
Next: eMTB @10-12s & 8"-12" pneumatic wheels; Got Strapped? d-(',')z

huh, that was getting REALLY slow in the end instead of just slipping tires. do you think this could be a consequence of can bus linked vescs with traction control enabled? would like to see this again without traction control, cause the 6374 engines should just immediately break loose the wheel! :o
