Evidence blades are not balanced at factory

[dellowwarren]

Hey guys

Took flight yesterday and on spool up the heli was very vibratey so I thought this can't be the blades but I was shocked to see this but hey you can't have everything your way, besides I have 0 tail wag so I am happy it's unbalanced blades then replacing servos which I still must but in time

A little vibration at low rpm has been reported as normal, I know mine does it WITH blades balanced, my buddies does it as well,unbalanced. I just bought some THunder Power blades, does it with those as well. I think they inherently have a spot where natural resonance kicks in, just power through that spot and all is well......
Oh, even with all the setup, and upgraded bearings,my 130X does too.....

You know I love this machine hey, got the blades balanced and just double checked the whole setup, took it apart and rebuilt it and bam on spool up smooth as a baby's bottom, well just a slight little vibration on start but goes away quick, cant wait to get the 130x and 300x

The stock blades are crap... My 450x damn near shook itself to pieces the first time I spun it up. Those blades actually had hairline cracks in them and were terribly out of balance.

Horizon Hobby replaced that set for me. The new set was so far out of balance that I threw them in the garbage.

I now run Align 3G blades, or Edge FBL blades.

If I'm feeling cheap, I'll buy the Aligns, if not I buy the Edge blades.

I still maintain a flybarred 450 3D and I have to say the eflite flybar CF blades look really good, the two pair I have had have had their spanwise CG pretty much dead on...

..BUT yep.. lol, out of balance.

Which is a shame because these are the easiest 335mm blades I have access to.

Once balanced, they do appear to track well and are nice and stiff. I'll admit I do like the flybar blade 335mm feel though. sigh... But.. for that price, you'd imagine they'd come balanced.

I just trashed a pair this week though, so I've put on some edges and these seem ok. bit shorter but ok.

Odd. My stock blades came quite well balanced; close enough that the only modification needed was a 1" strip of electrician's tape (not even balancing tape) to get them spot-on.

I suppose they'll have a few that are off by a bit. First I've heard of them coming *cracked* though.
Can't stand the Align blades myself. The missing centimeter makes the heli react slow and sluggish.

Any particular reason you feel the need to replace the stock servos, dellow? Mine are still going strong well over 300 packs down the line, and give excellent cyclic and tail response.

You know I did put on electrical tape and then checked the tracking and was perfect

No real intention to replace the servos but just nice to have spares for wen a real hard crash happens and not having to wait for spares
