If I had to do it all over again, yeah, I'd probably due heavy duty hardware if for no other reason than it makes me feel better....
But, with a carefully done setup the stock hardware can last. I've seriously been beating the snot out of my .46 w/ a Saito .91 the past few months on all stock hardware and it's held up incredibly well. I'm not gentle with it at all in the air and frankly, I'm suprised I have brought it home on several occasions in a hefty bag.
It's not that I'm that good of a pilot (quite the opposite really), but the fact that I'm not that it's held up to my abuse so well. I would recommend my setup to anyone... especially w/ the Saito .91. A great engine and I'll certainly be buying larger ones as I progress in the hobby.
