All, just broke out my old B4 and upgraded it with the +8 chassis. Additionally, it's been so long since I ran it, this will the first time I do so with lipo batteries. My issue is with the set screws that screw into the chassis. Blue thumbnuts are run onto them to hold down the battery strap. Problem is, I'm not getting many threads before the nut's stop. The setscrews are 1/2" long. Do you guys know of some longer 4-40 setscrews that will work better?

Thanks.
