Hoping one of you smart guys can help me out. My gear case is being replaced with a new one. They apparently no longer use the same gear ratio as my original and is being replaced with a new model. Question is will I now also have to replace my prop? Bigger or Smaller? I was running a 26 Trophy/27 Tempest.

I just want to get a little smarter on this so any help will be appreciated.
