Hey Tim,
could you please let me know how far the outer cover sits out from the block?
wondering if it would sit under our sst60 style cowls.
Cheers

i have two props identical, 23 long tube cleavers. only difference one has been thinned one hasnt, the thinned prop does 75mph all day long.
the thick one was only good for 73.2 :confused:
we run a nitro, 1.86-1 gears. on a 13ft mono 12x23 @6500rpm thats 75mph.
the larger box is 2.4-1
smaller box is better. you can put 2.4-1 gears in the nitro :eek:
haha thats a pic of my head. dont use that head but you blokes should be able to work out why :p:eek:
