From the "Why didn't I think of that" comes this new little shield for .21 size engines. It's from RB Products makers of fine 2-stroke engines. It's a simple metal shield that goes on the end of your engine, it comes with a collet and helps to protect grime and debris from getting into your engine bearings. It's very simple, and should prove to be very useful. Expect a retail of around $12.
