With glow slowly headed for extinction, I have decided to simplify, streamline and stock up so I will have what I need for the long haul.

I try to restrict all my modeling activity to .40 size glow and smaller. Pretty easy to stock parts in my shop for 3 or 4 sizes of engines all from the same manufacturer. Sure is nice to have whatever part I need on hand.

I don't think engine and part availability will get better in the future. Buy what you need now.
