This guy seems to sell a lot https://www.ebay.com/sch/joejack76/m.html?_nkw=&_armrs=1&_ipg=&_from= But don't buy anything before doing research on the prop angle, count, etc you need.
Battlers Connection makes good props. Certainly good enough for a cruiser like the Kitakami. They come in pairs, resulting in less than half the cost per prop. As for what props you need, what kind of motors are you using?
Sounds good. I posted this thread because the Kitakami's left prop lost a blade... Ill post pictures when I can... NRN
BC has some great props for you: http://battlersconnection.com/1-4-blade-25-pitch/ http://battlersconnection.com/3-4-3-blade-25-pitch/ Snipehunter also put together a Shapeways store to help the hobby. https://www.shapeways.com/shops/rc-warship-tech Great guys doing wonderful stuff for our hobby, hope you find what you need.
The 25 degree props are best. The more pitch the more speed you can get. But we are limited in speed. The lower the pitch the better acceleration you have and that’s what we want.
