Default Prop Size question

HI all, would a 9X7 APC grey prop, be too small for a .40
OS Max FP , this is for a twin plane , with 1 engine on each wing
according to top flites prop chart , these are too small . but these props were on plane when i got it . could it be since the plane is a twin engine, someone who owned it in past (no history on it)
was looking for more speed, hence the small props!

9x7 prop is OK on a .40 engine. But a 10x6 might be better. 9x7 is better for a fast plane. Sometimes ground clearance dictates a smaller diameter.

I run the APC 9x7 on my 2 OS40FP's they like it much better than the APC 10x6, the MAS (black) 10x6 is about in between
