This is the evolution of the Jumpinator, a board made for fun in skate and dirt parks.
The goal is minimal weight for maximum air and easy maneuverability.
I had to deal with bottoming out Trampa decks while landing so the consequence was to switch to the ultra-stiff DW II deck. Because the deck was out of stock everywhere I decided to buy the complete board and switch to E-Toxx Mini Helical Drives. My wallet is not amused but I am twice .
Board (weight: 7.66 kg / 16.89lb):
DW II deck
Matrix II metal trucks
F5 bindings and heelstraps
Rockstar II hubs
8” T1 tires
Mechanics (weight: tba):
E-Toxx mini helical drive 8T/40T 1:5 gearing
Electronics, motors & battery (weight: 3.3 kg / 7.28 lb):
Modified 6364 150kv motors
3x4s 30C 5Ah Zippy lipos
12s BMS 60A (120A peak)
Final weight approx. 12kg / 26.5 lb
This is the first and last time you see the board so fresh and clean
There are some things to prepare.
MBS doesn’t use bearing spacers but I prefer to have some. So time for old school work with saw and sandpaper, the spacers ended between 22.2mm and 22.5mm depending on the hub.
The countersink screws of the bindings are not flush with the deck and stick out a bit. I would damage them so better to fix this now.
Due to the drives I need to make cut outs at the tips of the deck or if I’m lazy at least at the rear. For now I’m just playing around with cut newspaper to find a nice shape.
Due to the concave of the deck it’s not that easy to mount enclosures compared to flat Trampa decks.
Right now the electronics look like this but I have to replace the ABS sheet and type of mounting for the DW II deck.
Also I would like to have an easy switchable battery (enclosure) without velcro, some kind of quick-action locking system…. Also thinking about better protection than the 0.04mm silicone cover only. But I guess i ghettomount it somehow before the winter starts otherwise it would take too long .
That’s it for now, I’m very excited to pick up the parcel from E-toxx which is waiting at the post office. Unfortunately it’s almost 1am here so I have to wait (and probably sleep) a couple of hours…
