I’m in the process of building a new high speed board, and wondering if I could get some input or feedback if anyone has built a board already that can actually go that fast. I know it’s been done before, but most of the one’s I’ve seen are highly customized and gigantic (like Moe Stooge’s board). I already built a board using mostly Torque Boards parts that can reliably do 36, and am looking to take it to the next level and push the limits a little bit. I only plan on going 45 wearing full face helmet and leathers because a crash at that speed can be catastrophic.
My biggest concern is not blowing out the controller trying to get that fast, so I’m wondering how much can be done with the gearing. The standard limit is 60,000 erpm for vesc controllers.
the following configuration gives me a maximum of 61,740 erpm, with 55.2 mph theoretical maximum 46 mph weighted:
Landyachtz Evo deck
2x 245kv Turnigy SK3
10s 30Q battery
2x FOCBOX VESC
107mm super fly’s
I’ve never seen anyone using a gearing ratio less than 2:1. Is there a reason for this? It would be easier for me to get the speed I need out of smaller wheels using like a 22T:36T gearing ratio and I would prefer this for a lower center of gravity. I’m not sure the 107mm superfly’s would be very good at that speed.
Anyone have any advice? Maybe anyone that has done this before and have something you would do differently?
