Re: Team Fire Force FW build
Actually I wouldn't recommend using the 5mm long ones, unless you have already ordered. We bought 5mm and soon went to 8mm long, as otherwise you only have a thread or two holding the grubs in position. Check my YouTube video to see the 8mm ones, they fit perfectly in all drills I have used.
We use 4 in each motor, you could probably get away with 2 in a lower power drill setup.
