RE: Evolution 58
hey grey hound man,
i have used a 3w 24 x 10 wooden prop and found it to be a good size for this engine!
i use a da 100 drill jig and it is worth its weight in gold. it takes about 90 seconds to do a prop and fits perfectly everytime.
i have never had a problem with my 58 and for a single it isnt that vibey.
good luck with your engine and i hope it serves you like mine has.
