Regarding the Power HD DSM44 servos, they look like they would be up the task on the TS1. I ordered some to try on my Alula EVO first and they look pretty amazing (on the bench at least). I made this video to show how fast and accurate they seem to be:
Sorry if it's a bit long, but wanted to make sure I showed consistent return to center and trim changes. I'm going to remove the Blue Arrow D05010MG servos I currently have installed on my Alula EVO and try these. Will report once I do.
