    How to calculate thrust for 5kg RC plane

    I'm trying to find the right motor that could carry/fly 5kg of RC Plane. What I've looked into so far has all given me the 1000kV for 900gram plane. Can we use that?

    Prop size vs KV value

    Another noob question. Is there a link to a chart that gives a guide to prop size to KV value of the motor? I've picked up 4 x 600kv motors for my scratch build and I get that low kv = large prop/ more torque but I can't see what size props to use. Thanks. :)
