so I have got your chassis but there are some problems.
First off: the front wheel touches the material that holds the mounting post. I have attached a pic to show what I mean.
Second, I think that the chassis is too flexible and will require some more stiffening.
Also, in the motor mount, can you add some more material on top of the holes that hold the screws to keep the motor from hopping?
Finally, what size of grab screws do I need to adjust the front axle? Can you use the NSR ones?
