not sure i dont think hard 3D would do it unless you had really loose blades or your blades at one time were really out of track, or if you had the woof, you know what they say spindles will bend if you even look at them

Replace the spindle and go fly it. Make sure your blades are tight enough in the grips and that the tracking is correct. If it happens again, then you need to look deeper.

((is that a known problem with the v1 ?))

Yes it is.Try a search on blade flip and uniflow.Two very good modifications to the v1.

In my opinion the V1 spindles are too small for 50 size blades and force applied to the spindle, I would recommend switching the head parts to the V2 stock setup it shouldn't cost that much.

I inverted the head on 2 V1's and they never woofed after that.
I never did convert to V2 parts but should have (mine stayed 30 size)

Good luck!!!

if he's been flying 3d already without getting the woof's then he isn't going to get it.

It is a good idea to upgrade the head to a V2 if you get the chance but the V1's do fly fine. I've been flying my 30 upgraded to a 50 for 3 years with no probs with the head.

Sorry mate but thats just not true.Very few of the v1s woofed in the first few gallons.But l think its something like 60 or 70% developed the woof after a year or so.l might be wrong,l usually am.l`m pleased you`ve got one that doesn`t,l think its about 50/50 at our club but one two year old r30 started woofing only three weeks ago and its never been flown hard.l`ve also seen tham develop the woofs when the`ve only been hovered.So far the head flip has fixed them all.BTW sorry about the sarcastic post,just having a laff with ya.

Being plastic and all I would figure after a year the head is wore out.
I had a V1 that had an old head and a new spindle (in my Airwolf) and you couldn't get it off the ground because it would shake violently while spooling up. I noticed that you could "rock" the head back and forth and watch the 2 small pins in the head move quite a bit. I changed the head (to a V2) and that cured the problem. V1 or V2 would be the same--the important thing is making sure the head is tight on the main shaft--probably the only real reason to get a metal head
