Long time coming, but I'm building a little bracket car
Sounds like a fun project. Hopefully somewhere down the road, i'll be able to start a thread like this myself. Although i wont have anywhere near the inventory you do. :mrgreen:
Depending on the final weight, i'm thinking a ballpark figure of 500hp to get where you want to go. I have to think one of your 4" arm engines would be best since you wont have to spin it as high and would be more durable in the long run.
