not in the midlands but worth posting down to
after the local experts had the prop off my falocn twice telling me 'yeah is fine' & wasting lots of time looking else where sent my prop to the above who said is knackered
Most prop balance m/c only balance up 3000 rpm whic I was told if its out of balance it would show by 3000 not true ! as I fold out but these can balance to lots more
Complete new 2 piece prop, custom made was about £400
