Bought wrong KV rating on motors

[Markus]

Hi

I wass a little quick and bought 2208 1100Kv motors. I have a 250 frame, and the biggest props that fit is 5". But even when i use 11,1v/3s lipo i will get around 200G per motor with 2 blade 8X3 props. My quad has a waight of 600G.

I have found a chart:
http://innov8tivedesigns.com/images/specs/Scorpion SII-2208-1100 Specs.htm

The charts sais.
7x6 propp 11.1V 7.68A85.2W9,505RPM444.1G of thrust.
So my thought now is maybe to mount 2X 5x3-6? prop. So i have 4 blades.
But i cant find any charts that compare bigger props with smaller.
Any thoughts of whats pitch i need ?

Hi mate why dont you just fit tri blades , low kv motor has big blades high kv use smaller blades like tri blades here are some to look at you may have to shop around for 5" blades i found some but may not fit spindle
