I just received one of the 40 size WM P-51's as a gift, not for any special occasion, just out of the blue....nice! Never worked with World Model planes before and wondered if it is a decent plane? I do have a Saito 72 coming back from repair and a OS 46 FX on the bench. Don't know if a 13-6 prop on the Saito would have clearance problems, It was close on my Pizzaz and ended up putting on larger wheels to gain some ground clearance. Which would you recommend(72 or 46)? Also have a Futaba flight pack with S3004 servos and was wondering if these would suffice, as no torque recommendations were in the so called manual.

Thanks,

Mike
