315mm or 325mm?

[Helifino]

What effects do blade lengths have on flight characteristics on a heli or does it really matter all that much?

On 400 size helis, for the average guy not a whole lot. Larger blades will tend to feel more "locked in" and more stable. They will also generate more lift.
A side note, Align measures the full length of their blades, so 325 aligns are acually 320 or 315 when measured from the bolt hole like other blade manufacturers do.

I had been flying 315's on my Trex and had an unfortunate glitch to cause a smackdown. I bought 325's from a local hobby shop and flew them about 4 or 5 flites. I switched back to 315's. I noticed the power seemed better with a shorter blade. I had trouble doing funnels with the 325's.

Thanks guys. I was looking at getting another set of blades(I'm not impressed with the stock blades)and I was leaning towards the 315's but wasn't quite sure on what effect it would have.

Let me know how you made out with the 315's.

Will do. I've got em on order and hopefully should have them by the weekend.

noel at align told me don't even bother with the 315s.

Helichoy,

How did you get a number to Align.

Would you mind passing that on due to they are quite slow with there e-mails?

Thanks,

Michael
