Scorpion HKIV-4025-1100 KV

As always, Scorpion makes a great motor. It’s smooth and relatively quiet. Only suggestion would be to make the flat spot the length of the shaft so any drive gear configuration could be used without requiring modification to the shaft.

The 4th generation is awesome

What a great motor. Their gold color is super stunning now. Instead of just being a flat kinda meh gold color, it is now a super bright and shiny gold with a CNC mirror finish that reflects light brilliantly. Extremely smooth running and just all around a very high quality motor that I am pleased to power my Raw 580 with. Comes with a sweet metal box that is a cool display piece on the workbench as a bonus. Thanks Scorpion and HeliDirect! RC Helis for Life!
