Duh

So I do get to work on my machine skills - cut one of the wheels too deep. Bonus is finished wheel is now down to 2.66 ounces. Lighter is better right. Never knew dumb could actually work out.

Am trying to figure out the suspension right now. Probably going to use RC off road shock absorbers and some sort of unequal length heim jointed rods. Sounds good in my head. Also really trying to narrow down my motor choices. Probably brushed gear heads for now. Guess I gotta finish the platform, calculate weight and figure out what size I need.

Remember, as I have learned. With motors, its the stall current that matters since a locked up motor could fry a bunch. Some small motors that draw less than 1/2 amp can easily exceed 5 amps at stall. And also remember that a motor that isnt moving must quickly go through stall therefore there is a momentary current draw spike at the stall current. Four motors like that would be 20 amps total!
