I just played a game on a backup gun. Hooray for backup guns! Lesson here, don't run Rayven flywheels no matter if the shaft fits seem tight or not! They WILL walk off the shaft sooner or later.
I was also seeing a very noticeable disparity in response between Rayven flywheels and Stryfe flywheels. The latter are lighter. Inertia may seem like your friend, but it is your enemy.
Off to hunt a good balanced set of Stryfe flywheels once again.
The upside is that it gives me an excuse to stick that shiny new 2500mAh battery in there and nix the JST-XH while I am at it.
