Blades and throttle trim...

Hi all, Can anyone reccomend wher I could get some Kyosho M24 main rotor blades from?
I have heard they work well with an upgraded motor, and have less pitch than the standard blades, so they are better for forward flight.

Does everyone here always have the throttle trim set to lowest setting when they fly there fps?
Is there anything wrong with using it, so your revs kick in a bit sooner???

This is the only place where I found m24 blades: https://www.ultimatehobbies.com/istar.asp?a=6&id=KYOCA1015!1012
And I mostly fly with throttle trim at center

Cool, thanks mate. I will look into getting some of those blades. Iv been looking for something better than the standard blades, but a bit more durable than the 8degree wooden blades I have been using.
I thought where you have the throttle trim was just personal preference, but wasnt entirely sure. I generally like mine at centre trim aswell.
Do you reckon it drains the batterie quicker have the trim up a bit?

Also, with having the throttle trim half way, when I crash, I must remember to cut throttle, aswell as throttle trim, as a few times I have only cut the throttle, but not the trim, walked up to the crashed heli, and the tail rotort is still going around! Not good!
