RE: Foam core .40 size profile fuse?
I know Im not a pro bro but I will weigh in on this one by saying I am building a .40 sized profile Yak 55 (Not the 54) right now. The design I am building came from Bill Mixon. He has built one already with a pro .46 that came out to be 4lbs. and It does pretty darn good (far better than the other .40 sized profile I have had (the sig ulti)). I watched him torque roll this bad boy for a long time last weekend. I will let you know how mine turns out fairly soon. I am hoping to get it going this comming weekend but thats pushing it.
