Nice note and photo from one of our more creative local builders:

Hi Dave,
I wanted to Thank you for the good $68.00 price on the Castle ECS yesterday and the advice on repairing the cold solder joint my bad one. If I cannot solve it I will hire Dicks service at RRC. Below is one of several current projects ( F-20 50” wingspan x 60” length at 6 pounds)
