Highspeed prop to Webra .61 racing and to Rossi R53..?
 

Anyone knows some prop for highest speed with Webra .61 racing and Rossi R53? APC 10x9? Fits maybe to both of these?

The answer more depends on the plane you plan on flying. If your plane is a fast, clean design, then I would try APC 8x9, 8x10, 9x9, etc. It won't do much good to try different props until you get set up to time the planes with a stop watch or radar gun. The other point I would like to make is that THE PERFECT PROP for your plane has a 1% chance of being commercially available, if you are really into the hobby of finding maximum speed for your plane, you will eventually need to become a prop maker or modifier. Off the shelf props are fine for those who just guess how fast their plane is, or speed loosely based on static rpm, or if the extra 5% isn't worth that much to you. Competition brings out the need for that last 1%. APC props are very easy to modify, and cheap to modify without worrying too much about the results.

Planes aren't finished yet... Rossi R53 will sit on a flatwinged EuroFighter, span 92 cm and length 115 cm, and believe it's quite fast. Webra is coming to my very own designed plane (quite much like F-18), span 100 cm and length 120, and I don't know if it will fly before it get's 120 mph as ground speed... :D
