Hi Guys, @bill_f 's two wheeler build thread reminded me about vertigo’s build I saw while ago on ES forum, and few days earlier I realised I just have ESC, 25H sprockets, motor and good battery cells laying around my shop. I decided to give this idea a try, I ordered Trampa Hypa hubs, as this build was supposed to be “budget” and “use what You have” parts only. I did quick sketch of parts, as Vertigo’s build is perfectly documented it wasn’t so hard, some dimensions are different, like my deck width is 174mm to accommodate 150mm long lipo cells, thus front linkages are a bit longer too. The deck and integral battery and esc compartment are made out of material known to knife and gun nuts as G10 which is simply glass fiber laminate, top deck is 5mm thick, sidecovers and bottom is 3,5mm black G10 I had laying around my shop. And now plot twist, are parts are HAND not CNC made, I cut them rougly to shape using paper templates on my bandsaw, then either milled them to required shape or ground on my knifemaking belt grinder.
As I don’t have 10S battery charger and wanted this board to run on 10S voltage, I decided to split the battery pack into two 5S2P packs, connected via loop key to 10S2P pack when board is powered on.
When loop key is taken out it’s possible to charge and balance two 5S2P packs separately (I have turnigy reactor quadcore charger, it supports up to 6S). I made special charging harness, and it uses 12 pin binder 680 series connector for balancing and charging.
Everything inside is packed pretty tight, as this build was planned around components I had.
Now aluminium parts need just some finishing and bead blasting and then I can get them anodized black. This should be fun to ride!
