Looks great! Was looking forward to seeing the original version run.

Don't rely on the clutch slipping during spin-up if you can help it... all the time its slipping its heating up (a lot)... that heat has to go somewhere, probably directly into your weapon motors which will help them cook quickly.

Asking 3 large brushless motors to run together in perfect time is an interesting challenge, hope it works well for you guys! Id certainly design in being able to run on 2, or even one motor rather than 3 encase you run into last minute timing issues.
