I used an RCV 1.20 in mine. It flies very well and with a scale size prop ( 17 X12 3 blader), it looks the part.
What rpm are you getting with the 17x12 3-blader?
Ever thought about using Solo 3-bladed props with round tips? Solo blades and hub look good. Check them out here: [link]http://www.soloprops.com/[/link]
