WA check members gallery and NH official thread for lots of hammer pics..got a few in my gallery.

my opinion for propeller since my hammer is for fun boat and not for racing so far, i'm satisfied with stock one for the reason that i don't worry alot if i hit hard debris or run aground, coz with plastic prop it will absorb the inpact and break and will not damage the shaft, tubing even the hull, got 3 times prop breaks eversince and it only cost my $8, if i'm using metal prop i do no what gonna happen, maybe more..but if i'll go racing or challenging with somebody i'll get metal prop,or for a reserve one might be.

with nitro fuel i started 20%nitro 18% oil, then 14% oil, now i'm using 20%nitro 12% oil not really particular with brands...i prefer 20/14 coz its easy to start and enough lubrication...i'm worried a little with 12% oil but i add few drops of castor oil..got it from hobbytown.
