J.M: I have looked into useing those a-arms. Unfortunatly they are way too wide at the bulkhead for the B4 bulkhead and the rear E4 a-arm mounts. I was considering finding some bulkheads that would work but there's all kinds of problems that come up with using those a-arms. With making my own a-arms I have a lot of flexibility and can make them work perfectly with my design.
Talked to my Tech ed teacher today about the cnc mill we have at the school. He said it can do plastic and it appears to be 3-axis. They just haven't done alot with it becuase its brand new and they haven't had a ton of time to work with the programs and such.. so their is a possibility that if I can learn how to program the mill I can make milled delrin parts which would be alot stronger then Abs 3d printed parts AND stronger then composite a-arms such as the one's found on the B4. I'll have to look into this possibility more seriously.
I gave my teacher my Solidworks drawing for the rear a-arms and he is going to print one of them early next week so I can make sure it fits.
Today I got a lipo cradle done. The car will have a upper chassis so the battery is going to be slid in thru the side and the upper chassis will hold it down. I'm going to be making a quick release battery door such as the one I made earlier on with my original design.The esc and receiver look like they will fit perfectly right behind the servo. I cut the cradle slightly to large around the edges around the chassis so after I get it bolted to the chassis I will use the aluminum chassis as a guide and cut the over-hang off with the scroll saw for a nice even edge.
I think it will look much nicer when installed on the final Carbon chassis.
