As the title suggests, I am beginning my latest build that I am calling the "Monster Board".
This will be a huge skate board. It will be over 4 feet long and 28 inches wide. The wheels are 13 inch kids ATV tires. It will be four wheel drive using two Astro Flight 3210 motors (one per axle). It will be live axle (no differentials). For a street board, solid axles do not work well. But, for an off road application, they work great! The board will have full suspension with 4 to 5 inches of tavel and 8 inches of ground clearance. It will have a total system power potential of nearly 10,000 watts! It will be geared for 15 to 20mph depending on how well it runs at verious speeds. This means it will have crazy torque! The pack will be 6S, 40ah Multistar Lipo running through two Castle Creations ESCs. The axle assemblies (trucks) will consist of go-kart axles, hubs, sprockets, etc. I am building this as a true all terrain board capable of going pretty much anywhere, including snow. Odds are it will not be running this winter. But, I really want it for next year. I plan on being able to tow my son around behind it.....
Make no mistake, it will be a BRUTE! I expect it to weigh upwards of 75 to 80 pounds. It will be, essentially, a 4X4 go-kart slightly shrunk down that you stand on a lean to steer.
For those of you familiar with my E-bike drive systems, this board will use two of my DaVinci Drives. The motors will run up at 10,000 RPM spinning a toothed belt to a jackshaft, then a #35 kart chain from the jackshaft to the axle. The front and rear axle assemblies will be identical running their own independant drive system.
This is a project I have been thinking about for a few years now and I am finally pulling the trigger on it.
So far I have the following parts in hand;
Heim joints for the suspension
DaVinci Drives and system parts
misc aluminum and steel for the suspension and chassis
I have the following items on order for it;
I am guessing it will take around 6 months to get it running. So, be prepared for a long wait. I have a couple huge OEM projects for clients that are taking up most of my spare time. But, I really want this thing running! This is one of the very few projects my wife has shown an interest in.
I will post pictures as I have them.
