Red, speaking of Model Labs in your post, who came up with the safety needle valve adjuster that they sent to new members?
I still have one in my flight box just to show people that there are complicated ways to injure yourself while adjusting needle valves. Personally, I would rather just stick my finger in the prop directly rather than having all that additional flying plastic in my face when I get it and my finger in the prop.

You were right about a good idea being poorly executed. They lead a lot of people in the DFW metroplex down the garden path.
