Marty,

More info please.. When did this start occurring? After a crash? It could be a lot of things. Did you balance your tail assembly?

Check 2 things: tail shaft and motor shaft.

If you have a vbar pro firmware, a vibration analysis will definitely point out what is the cause.

Have you check the belt for any damage also the gears and the bearing in the tail?

You said both servo frame were broken, what about the third lower support?

Hmmm... I was just thinking. Were they really out of whack balance wise?

I thought they were extremely good value. You see, I absolutely hate balancing blades, must be some mental block on my part. So I've not really gone out to buy really really cheap sub-$10 blades.

On the 2 pairs of Align 325 3G's I have found the CG's pretty much spot on, just needed 1 tiny piece of sellotape on the lighter blade and good to go. They're great, only about $18 here. Well worth the lack of hassle. They're currently mounted on my B450 FBL.

I haven't trashed my stock SABs on my mini P. These were essentially spot on so no sticky tape.

I tkink I mixed up to sets of blades,yours,Marty.

Just checked I put a 3G blade on with a F blade im a plonker of first class honors.
