The heli flew good but I had a very slight drift in a tail slide i was fighting so i decided to go back and recheck some balancing. The last 10 blades and 4 paddles were almost perfect so they never needed much attention.

How much tape on a align 425D is acceptable before you return a pair of blades?

I have put all 3 tracking foil tape on one end of the 425D blemished and its still way out of balance just for CG let alone total weight. [maybe 6 of the foil tape that comes with the blade might do it] the thick paper backing for the foil tape almost balances it. this is issue 1 with align blades.

I have the CF flybar paddles and noticed the flaybar dropped very heavy on one side, it took a huge nylon 9650 gear on top to balance it. I had to put the stock paddles on and they are balanced perfect.

No wonder I have a a very very slight drift. Its my fault for not checking when i put it together Align has been really good in the past I cant trust em now and either should you lol

[[I just tried to balance the 425 for CG only to get just the CG balanced it took my red and blue trex600 funtek tracking tape wrapped around at the end plus a 2" x5" wide strip of my readyheli its a heli thing window sticker. I didnt even try putting more tape on the CG of other blade to balance both equally Im so fed up with these 425 align blemished blades]]

Get some good blades and be done with it.

Still asking why

Unbalanced blades and or paddles will cause vibrations, drifts are more of adjustments issues either mechanical and or radio settings.

I post with slyster all the time, but linky no worky

Im well aware about vibrations and the logitech gyros [any gyro]

in almost 2 years I have never had a set of blades this bad.

Not even the dealextreme 12 dollar CF 325,s were this bad.

my main question is how much tape is acceptable before you return them?

OK bottom line do they go back or not.

it took 4.5 wraps around the blade with black tape on 1 blade just to get CG right

It took 5 wraps around CG on the opposite blade to get overall balance.

I just want to know if im out of line for complaining to the place where I bought them online

Hmmm, I have never had a set that out of balance. Sounds like they may well be defective.

My friend just got a set of CY Radix blades for his Trex that were 3.2 grams out. He called, and they said "send them back".
He has a new set coming.

So even the best blades can be out. Its all about customer service at that point.

Still asking why

For 325s I LOVE the Thunder Powers. The set I have were balanced and tracked dead on out of the box. They fly really well. Lots of pop and dont bog. I have not had a chance to try the 325 Radix, but I have the 600s. Either is great, they are both very nice blades.

just remember,
by adding tape to the end of the blades you mess up the C of G as you are moving it.. and when the blade is rotating they will come out of track as one C of G is different

What i do, put them on a sensitive balancer find and mark the c of g on both blades, that is where you need to add the weight to balance, not on the tip...

it depends how precise you want it, most blades will be ok, but i look for such a precision to the point of being obsessive, , i weight blades to within the weight of a human hair, i also do tail blades the same way.

And i have no vibes at all,

Matt

matt maybe you missread what i posted

I thought i was pretty clear stating that i was balancing CG

I also said I would not balance both equaly, but sinse then i have.

[[[ What i do, put them on a sensitive balancer find and mark the c of g on both blades, that is where you need to add the weight to balance, not on the tip...]]]

not picking on you bud but i think you need balancing lessons. You first put tape on the end of the light tipped blade so that both blades have the same CG.[this is very important] you then mark on the blades where CG is and then balance both blades by adding tape to the CG.

you should watch the finless vid on balancing

yeah i misread your post, sorry,

As we have said exactly the same.

You find your c of G first, if they are the same, i mark mine with a pencil mark, then that is where i add the weight..

If the c of g is different then as you correctly said you add weight to the end of the lighter blade to equal the c of g..

But if the c of g are equal then you dont add weight to the tip or you will mess it up...

I think we both have mis read each others posts i did not pick up you were trying to find the C of G... so sorry if i misread.. i have never had to balance the c of g on my blades as they have always been pretty spot on, i normally have to add a little to the c of g to ensure both blades weigh the same..

And yes Finless bobs video are great for learning tips..

I have never had a CG problem this bad either. maybe 40 pairs only needed tracking tape. at one end

and the align 425 blemished blades suck and if the guy at the online store we all know doesnt return my email i will post and let everyone know who to stay away from.

I never mess with blades anymore. I buy a good quality set and never look back. Sure they are a little more money but in my opinion worth it. If you don't believe me, check my gallary and see what happened to a Sceadu Evo 50 that I had awhile back.

It's a complex, costly, glow powered anti-gravity machine!
