most of the info i have found on prop modding seems to relate to octura or abc props. the few people i have talked to about cutting a prather said the cuts for other props didn't help a prather-mostly made them worse. i've done a few octura's, and had good luck so far-picked up 3 mph on my .21 tunnel (thanx to topfuel443!). have a couple prathers, and was wondering where to start?any suggestions? pics would be nice. thanx in advance.
