Did you upgrade? Which kind did you get and how important do you think it is to have them? Just wondering how many bought them.

I am on the fence. After seeing the post with the heli exploding in flight (hover I think it was), I am thinking maybe its good insurance, but I wonder if its really needed. If my head speed is 2140 or below. Would you think it will hold up as long as inspections are done periodically?

Not only is it cheap insurance, it's also a good idea. Even with periodic inspections, there's always going to be a chance.....

Hell... I can fix that.

Why risk it at high headspeeds.

Spend 60 bucks and get the grips, or spend a LOT more if one of the grips comes apart.

I installed them during my initial build. One less thing to worry about IMHO.

I just read the trextuning article.

My Align metal grips came with two radial bearings. The article said theirs did not.

What about everyone else. Did yours come with two bearings per grip?

I wonder if he got a pre-production run or something.

Man that scared me. I though I slept through the assembly and didn't notice the bearings were missing.

I'm happy with mine. They also seemed to improve the dampening. Key word seemed.

I have them. do they make a difference? Dunno. The plastic ones were upgraded over the first version that caused a problem. My evo 50 grips never ever let me down but I do only run 1900 rpm on that heli. The trex runs 2120rpm. I just put them there for security. They look nice and seem to be good quality. Blades fit perfectly. I am happy with the upgrade.

Metal Grips

Get'm, If I had the extra cash I would buy them for you, thats how sure I am, some disagree however on metal grips the evidence why you should run them is all over Runryder.com IMO Metal grips belong on a 600N....all of them!

Both of mine have metal grips. My first one was eating dampers every 1/2 gallon of fuel. After I put the metal grips on the dampers lasted well over 8 gallons (but they're probably due to be changed). The plastic grips get sloppy from the bearing races sinking into the plastic under load, subsequently allowing for more play. This additional play causes the dampers to die. Just my observation / opinion.

Just one report of a blade getting slung because of a cracked plastic grip should be enough to persuade you. I'm sure that there are plenty of plastic-grip cheerleaders who will tell you that the grips themselves weren't responsible for the blades coming off. But we're talking about Pacific Rim plastic from a company who's QC, while not horrible, is sometimes questionable.

Ditto .... buy the metal grips. Its the best $54 upgrade bang for the buck. Especially if your running your head speed at over 2000 rpm.

Thanks, Your thread is what got me to thinking. I would love to think since Danny Sabo flies with plastic grips I would be fine, but alas its not true.

I was also wondering is the majority of folks upgraded right away, because .... a 50's a dif animal, other than a 30?

If 50 % of the folks upgraded, the failure rate might be lower than is accurate. In other words, the low failure rate might be misleading.

I guess I have no choice but to buy them, but I would prefer to have plastic that is safe as opposed to the issues metal grips give you. I won't see any improvements I can really use personally, but I can see the downside alright and I am not talking money.

The resiliance of the plastic grips helps dampen the tortureous vibrations to the rest of the heli. My main reason for holding back. Additionally in a crash metal grips will take out other things. We don't go out to crash, but it happens. Would prefer a cheap plastic grip when (if ) that happens to save other more expensive components.

Its a compromise for sure. And safety is the number one concern, so I suspect Ill be getting them very soon.

I am a little surprised more aren't jumping in this thread indicating they have the metal main blade grips.

Other than the safety issues, I actually preferred the way the 600N flew with the plastic grips as opposed to the metal grips. The cyclic response is a little more crisp with the metals but on hard collective changes the head on my helicopter shudders or wobbles a little bit. It didn't do that with the plastic grips, I'm sure b/c the plastic acted as a dampener. Since I run a high headspeed however, I won't use the plastic grips anymore after having one fail.

I saw a buddy of mine throw a mainblade on a trex 600E, Cracked the canopy in the air, the other blade hit his 300 usd Lipo, Ouch and that was before it hit the ground, all for runnning plastic grips, stick to metal.
