I m almost complete with my first rc plane i.e Spitfire...just left with motor mounting as i don't have a propeller...i need some info on propellers like relation between kv rating of motor & size of propellers, difference between reduction drive(RD) & direct drive(DD) etc..
Any kind of suggestions r welcomed  
i m attaching few pics of build

it has Ailerons,Elevators,Flaps & Spoilers...final assembly of electronics is yet to b done

Great build Aman! But being a low winger, it going to be difficult to fly.
