RE: X-Treme Composite Hatta Special 19-13
You can try Xoar props, too. I have some turnigy props, and while the wood and overall shape look nice, the leading and trailing edges are complete junk. I noticed a TON of more pull when I switched from a Turnigy to an APC prop - immediately, just driving the plane onto the field.
Xoar props look much nicer, but it was too windy today for my first test flights on a Xoar 18x13.
I think the Hatta props are wide blade props.
