There’s no flying this week due to the cycling event and all the roads being closed. I’m going to use the time to try and fix my HubSan X4. It looks like the problem is power related, but I can’t find the cause. One minute, there’s no power, then it binds leaving one eye blinking at me. Then I managed to get it to work briefly, but it was completely out of trim. I really need to examine it in more detail to try and find the cause.
