Hi I'm gonna use the motor and esc setup from an Conscendo advanced on an old Swift II. On the photos you can see the 30 amp esc can run both 3 and 4S. The propellar from the Conscendo is an 9x5-7x5 sized one. It's to large for the mount on the swift and what size can i use on this setup for both 3 and 4s? I know the propellar should be smaller when using 4S.
