got a link to the power star with dimensions?
I finished milling some custom servo mounts and have a nice tight fit, I also backed it with a standard size servo to get perspective on how far it hangs on the side of the chassis if someone tried to use a standard servo setup, which could be possible with some modification:
I'd be willing sell mini aluminum servo mounts, or a 2mm carbon brace to extend the servo mounting holes to fit a standard servo if anyone happens to have any interest.
