Well I finally got the opportunity to test a Medusa V2 36mm-60mm-2200Kv motor. I shouldn't be surprised after all the testing I did in the Yusa with the shorter 50mm, but wow what a huge difference.
This thing rocked my Losi 8. Now Medusa has the 70mm and 80mm, after what this thing delivered, I am not sure you would even really need that power unless you were really pushing things.
