Align T-REX 600N 700N > Check your blade grips

Just to be safe everyone better check their main blade grips. There has been a report of the grip splitting. Hopefully it's an isolated incident but if not this could be very serious.

I looked at the thread the and the guy with the problem posted this picture:




Sure doesn't look anything like the beefy grips I have in my kit.

It does say in the manual that overtightening the blade bolts can cause this,,maybe it was user error

Thats because those are NOT Trex 600 Nitro blade grips. Those are the older 600E grips for certain. Look at the conical bolt area on the top then look at your nitro grips. Very different. I think he replaced his blade grips with some of the older E version grips after his last crash (probably because the nitro ones are hard to find in stock). He did say that these grips were new that day out of the package. Looks like user error for sure, unless these grips were mistakenly included in his nitro kit.

The point of my long post, he made a mistake by putting in the wrong grips. They are DEFINITELY not the Nitro grips and should not have been used (but we all make mistakes, not knocking the guy at all).

Perhaps the title should be changed to "Dont use the wrong parts on your 600N.": hehe - but that wouldnt help further the RR rumor and paranoia game

If there no good on the nitro version then surely there may be a problem using them on the E versions.

With motors getting faster and lipos getting better , think I may change my ones on my E to the same as my N ones.

Even if they end up being the electric grips it's valuable information. With the shortage of parts it would only be a matter of time before someone else did this when they couldn't get the nitro grips. I purchased a spare set of grips and now need to go back and make sure they were the nitro version. It's also good for those that fly both versions to know the parts are not really interchangeable.

Good point man, I am just making sure people dont jump to too many conclusions as they often do on the forums.

I went to the metal blade grips from the start. It just feels safer. I do it on all my 600s.

Many 90 size helis comfortably run plastic grips

I'm wondering what would make the E grips different than the N grips, both swing 600mm blades, at similar speeds. I would think similar forces would be exerted on both types of grips.

The 600 nitro can get higher headspeeds than the standard electric set up

The e heli's don't have to deal with the same vibration levels. Or the same power pulses the nitro does. I'm guessing they saw an opportunity to improve the design so they did.

Lots of the highpower e setups run WAY higher headspeeds (2300-2400) than the nitro does. At 2300 we are revving 19550 on a hyper.. well beyond the power band, probably past any logical 'drop it into the torque' model.

But I'll bet you there aren't many high rpm rigs 2200+ running the stock plastic electric grips. Most of us aren't that confortable swinging much over 2K without a metal head to back it up.

I flew my plastic grips for a while. But they definately have more 'give' then the metal version. Ripping out the bolt like the picture shows looks like someone got on the end of a bunch of leverage and stress fractured them. Or they needed spacers and just cranked them down? Dunno.

One known failure on a completely different part, isn't something that will put me on edge.

Thanks for info

The first series of the electric grips were faulty. People were slinging blades when the E600 first came out. Align fixed the problem. I cannot tell if those are the older E600 grips or not.

According to the original poster on the other forum these were the grips that came with his kit. According to Align's website there is no difference in the blade grips. Both the 600e and 600n use part # H60003-1 for the main grips. I just checked the spare set I purchased a few weeks ago and they are H60003-1 and look like the ones in the picture. It's hard to be 100% certain since the picture is fuzzy and at an angle but they look pretty close. The spares I have are also the same as the ones that came with my kit and are currently on my 600n.

fuzzy or not it's an incredibly obvious difference between the grips in the picture and the grips I have in my kit and on my heli. The grips that came with my kit and the grips that came in my friends kit are most definitely beefier/heavier grips especially around the bolt hole that holds the blades to the grips. My kit is the pro model and my friends is the sport model, same beefy grips in both kits. No comparison, night and day difference between the picture and mine.

Before this heli I flew a raptor 50 with plastic grips for much of the time. One thing I can say with certainty is plastic blade grips weren't a problem on the raptor. I don't believe plastic blade grips are inherently bad, heck some 90's use them. Perhaps some kits came with the old original weak, flawed blade grips that came on the "E" version when it first came out but that's sounds unlikely.

There is a very fine line between "hobby" and "mental illness."

That grip definately looks like its been used and abused. Look at the bottom side and you can see where the blade wore a shiney spot on it, and for all we know it could have been crashed and caused the split. Also, it looks more like the original grips I got with my 600E and were replaced by align for the newer ones that were beefier, all IMHO of coarse.

Honey, I just need this one more thing and then I'm set..
