Huh? I didn't pick YOU to "attack". It's not about YOU nor were my comments ad hominem. They were about the contradiction. You were shouting (typing in capitals) about O.S. Even if the inquirer had not specifically pointed out that money was tight which places O.S. well down the prefer to pay pile, as I mentioned, O.S. have had their own problems with the 91FX amply documented here. Why pay twice as much if it'll still likely present problems seems a reasonable line of thought and worthy of pointing out to me? O.S. ain't the everything O.S. do is gold brand the label once represented. 46FX liner disaster exacerbated by years of denial, premature 50SX bearing failures, 91FX carburation issues...et al.

Yes, heard of it, even observed it, but been around aeromodelling long enough to know it's better to 'eat your greens' if you have to by paying the extra to buy new and avoid someone else's 'problem child'. People only boast about their successes, and I don't believe in the hardly run in only driven to church on Sundays by granny bargain used anything any more than I do in the Easter Bunny. A new engine comes with warranty, which in the US (we envy you) actually means something. A second hand one doesn't.

Aren't you the one SHOUTING? I think you unnecessarily personalised comments which weren't directed ad hominem at all. Peace pardner.
