Is there such a thing, I've tried my hand at building and found that I just don't have the patience for it. I'm looking for a light arf and was looking at the top cap or the knife or maybe a future arf sledge if they come out....the knife seems so expensive though, any thoughts here....I plan to rob Billy Hell of his idea about using axi4120/14 to make a powerful electric 3d, he never did say the final weight but from what I gather it's 4.5 pounds because if you have 150 oz thrust and it's 2 to 1 then... a little lighter than that would be fantastic though.....and oh yah it has to be a profile

Thanks guys
