what are the suitable props for 3D flight and break-in?

GC,


For break-in I use a 10x7, or 10.5x7 prop.

For normal flights, a 10.5x6, 10.5x7, 9.5x8, 11x6, 11x7, 11.5x5, 11.5x6, 12x6, 12.25x3.75 and several other sizes are good and usable. Stay with APC, Bolly and Graupner and don't use props of dubious quality.

I have been using a 10x8 and love it on this prop.

I use the 10x8 on my patriot and if I remember I broke it in gently on that prop
