Had a friend of mine with 700 le version using the 690 d align blades , is it possible the blades can cause 2 crashes in a row? The blades are split in the seam on the leading edge both times, what gives? See pick.

Hard to tell if the blades split before the crash or after, although there have been reports of blades failing.

I have had good results with these blades.

What I can see in the pic is a blade bolt missing.

Hi- I read that Align 600mm had a quality control issue. I'm not sure if the 690 where included in there. You might wanna check with Horizon hobby. Here is the post

That recall is really old info regarding the "C" blades and not associated with the "D" line what so ever. I've been flying Align D's exclusively for a couple years now (600's and 690's)and haven't had one single problem. But hey, they send us reps the stuff that's not defective! J/K

+1 I remember when that report came out a LONG time ago. In fact all blades in that notice were supposed to be returned by Oct 2007. I havent heard of any reports of blade failure since then

Not really, but if a set of blades "looked" liked they survived a crash and were flown again without replacement. Its possible for them to come apart and cause a crash.

Yea, I was wondering the same thing. The main blade grip bolt is missing and the blade that goes there is just hanging off the heli.
What is up with that?

If that bolt came off in flight......

As HiroboFreak notes in the second post, where's the blade bolt? No sign that it's caused any damage to the blade grip in the crash. Looks like it was missing before it went in.

blade bolt
The blade bolt and part of the blade (looks like the other side) was taken off , then i decided to take a pick before anything else was taken off, sorry bout that.
This is the second time this has happened , and the only thing i can think of is the blades they both were split down the seam on the leading edge , this happened on both crashes .

That crash and the subsequent crash was caused by vibration. Such a high vibration at prolonged periods of time caused the tail boom to break right where it was pinned to the helicopter. Boom went into the blades in flight resulting in the carnage you see now.

It might be better if you could describe the events leading up the the mess we see before us. What sounds were heard just before the incident (especially from the rotor disc) and did you see anything come off just before? hmmmm...I don't know this seems like a mechanical failure from somewhere else. The blades look like they were just colatteral damage..

i was there and He was doing piro tic-tocs what seams to happening from what i can tell is that the Horizonal clamp that holds the Boom braces is moving back and forth (not tight on the boom) side to side is good but not up and down. in turn causing the boom to flex to the point to where it breaks the boom at the boomblock. I feel if he PINS that clamp his problem will be solved.... just my .02

Love a Twitchy Heli.... :) and Remmington Model 700
