I have a header/extension I'm using on my YS 140 and it recently broke at the location where the rigid part joins the flexible (bellows) extension. I purchased the header used with the model (Sequel) and therefore don't know what make it is. It must have at least a few hundred flights on it. Is it possible to silver solder or repair the unit in another way? I checked on Central Hobbies' web site and didn't see anything that looks like it. Any assistance would be appreciated. Thanks, Don
