Trampa StreetCarver, E-Toxx MiniDirectDrive, MTB Trucks, Gummies, 6374, 12S, Steering Damper

Updates are looking MEAN. I’m really interested on what the ride quality will be like on the gummies compared to say the superfly 107mm. Those wheels are huge but a good chunk of it isn’t urethane.

Also what the reasoning for DD on a street build? Wouldn’t you prefer belt for less noise?

Also what enclosure are you using? I’m assuming it is going underneath possibly? What battery setup are you planning to run?

That’s just… wow… you did it again.

Really wanna say thank you for your kind replys guys. Its a big pleassure to share my stuff with people who love this shit. Big motivation everytime :kissing_heart:

Yes without springs will be crazy… not going to try this… only for sick pics But planning to play around with some kind of steering damper if possible!

Yap will be really interresting for sure.

yes the noise factor would be better for sure with a belt … But: -Loving the ultra compact look -Autumn is known for alot debris on the streets -Full braking performance possible, far behind any Beltsystem -will use it also with pneumatics in light/dirt/offroad

Battery Setup will be Sony VTC6 in 12S Config,How many P depends on enclosure.

Option Nr1 is Trampa Enclosure, limited to 12S4P, already got one prepered with CNC cutted Slots and Holes… it was such a mess last time by hand…

Option Nr2 will apear hopefully tomorrow… Thinking about for longer and just give it a try this time… Maybe (-; I hope its not too bulky, 50mm height, Trampa one is really slim with nearly 30mm height…

Today the engines arrived, quick mockup for clearence check…

Looks Nice

Let me know how your enclosure works out. CNC is dope. Yes, I did the hand cutting + mini circular saw way before. It is a lot of hard work and time consuming than Frank’s @trampa original thread on the matter suggests. You have to saw and saw and saw till your arm falls out.

One issue is that the space is so tight. I had to remove the neoprene from the aluminum L-profile and now will use just the silicone rubber sheet on them because every bit of space counts. I am still trying to shove the antispark with on/off button in there… I barely have room… very concerned if I can make this fit. I think instead of following Frank’s design to the letter I should have connected the battery packs with 12AWG wire at the tops rather than diagonal because that is just lost space. If I had just like 2-3 more cm everything would fit so comfortably. Or if I chop two cells off and make it a 10s4p… but that just feels like a sad, sad, way to go… after planning for 12s.

Any ideas? Smaller AWG wire on the ends of the battery to the vesc’s + antispark and xt 60’s instead of xt 90’s? maybe bullet connectors will save more space? I am having trouble folding the wires to all fit in. No BMS because using a 12s charger from Amazon.

Tell me about it. I had to 3d print these end caps, in order to fit everything inside, which is working perfectly fine btw. … But I would love some more height on the trampa enclosure though. But aren’t @trampa working on a new one ?

6 Likes

So your batteries or Vesc’s extend into that 3d printed end cap I suppose?

Yes, height is a concern… I think I may have to re-do my pack padding:

I created a sandwich with total height: 27.75mm + tape height

  1. 1.5mm tufnol (bottom)
  2. 3mm neoprene (battery cushioning bottom)
  3. 19mm (18650 18mm + .5mm battery enclosure)
  4. 3mm neoprene (battery cushioning top)
  5. 1.5mm tufnol (top)
  6. 0.75mm silicone rubber sheet

I thought I could just squeeze the neoprene down to fit from 6mm total to like 2mm but it is more resilient than I expected. I think I will remove the neoprene part of the sandwich entirely.

Yes exactly

Lol… and you have a BMS in there… ok I should stop complaining. That’s some Jedi sh!t

Yes and a 10s5p battery. Without the end caps, i would have problems. But i do not like that tight fit at all. Looking forward to se what you end up with :smiley:

HI, I spotted some things:

The balancer leads should be layed in a curve, each time they cross a cell block. This will allow the flex. You have taped them down in a straight line, which will put strain on the balance leads once you step on the board and flex it. Have A look how I did it.

I would tape the cell block interconnecting AWG wire to the cell blocks itself >> just next to the solder joint. This will grantee that there is no movement in the nickel strip. The only movement is in the centre of the cable once you taped the cable ends to the cell blocks.

If you use the aluminium L-Profiles, make sure to use rubber cable feed throughs

I don’t know how I missed this build, amazing as always Jens.

I’m going to make the same build but with HS11 deck, ultimate hangers with carver baseplates and 107mm Flys, I already had the Carver deck before so I wanted something different this time, the carver deck sits very high from the ground on pneumatics, I dont like that much either.

I’m just worried about the clearance as I haven’t seen anyone with a HS11 or MTB Holy Pro deck, ultimate hangers and street wheels, maybe because there were no options before but the 97mm flys

Just out of curiosity, why did you decide on the HS11 over the other Trampa offerings?

Because:

  1. I already had the Carver deck, I wanted something different
  2. The HS11 shape is way nicer than the carver
  3. The carver sits too high from the ground on 8" pneumatics, I like HS11 stance more
  4. I will be able to convert it to full MTB
  5. According to some, 107mm Flywheels give enough room to avoid the deck to touch the ground
  6. The HS11 has more room underneath to run silicone wires between individual packs, planning to run 12S5P
  7. The HS11 is cheaper than the Holy Pro 35
  8. The HS11 has this slimmed belt shape that makes it better looking than the street carve deck wihich is more plain

Carve deck:

HS11 deck

However nothing in this life is perfect so here are the negatives:

  1. The HS11 I chose weights 2900g (16ply) vs 2500g (15ply)
  2. Deck clearance might be an issue on full leans (I’m hopping not to be an issue, I’ll have to test it myself when I get the 107mm Flys)
  3. I’ll have to swap axles on the ultimate trucks as the originals are too long for street wheels

Wow, awesome explanation all around. Thanks! BTW, I have loved reading through all your builds and learning from them! Look forward to watching this one as well!

You can use spacers to fit the street wheels. Replacing the axles can be painful. They are pressed in and won’t come out easily.
