I have a HIMAXX 4100 brushless motor that was used in a gear box with a 10x8 GWS prop with success. But I prefer direct drive and it came with a collet adapter for APC props.
My questions are can I use it without gears for direct drive with an APC 10x7 since it came with the adapter? Or should I use even a lower-higher pitch-diameter prop?
I don't have a Motocalc.
