I have about 10 Castle products and not problems yet. This one is working well in a giant YAK 54 from Aeroworks. Most of the other items from CC are helicopter ESC. They have great support and they tell you never to trash a wrecked ESC as they will trade it in. I thought I had a problem but sent in datalogs to CC and it turned out to be a bad battery.
