Default RE: what size propeller

ORIGINAL: luker737
I just bought a Tiger 60 airplane it came with a Tower 61 and a 12x6 prop. on it. I have two charts for props to engine and this time i have two different answers one says use a 12x6 and the other says use a 13x6 . should i go 12x6 or 13x6 ? I'm not looking for speed but easy take off and nice and easy fling.
From the manual:
Propeller: For "break-in" and most trainer and sport airplanes, we suggest a Top Flite 11x7 Propeller (TOPQ5110). A 12x6 Propeller (TOPQ5140) may also be used.
=============
From there, experiment until you find what you like best. I've used four props on .61 two strokes:
11x7 - worked ok
12 x 6 - works very well, my "first choice" for the engine on a sport plane
13x4W - works well, great thrust, costs a lot more than 12x6
13x5 - engine seemed to be overloaded. Maybe it was too new for the prop, never tried it again
