Just finished building and flying my 700 (one flight) and then I read a post about the spindle bolts breaking. Was this for sure and issue or another rumor to make Align look bad? I did check mine and one had a wobble and the other one was fine. If so I have some black M6X20 hex bolts ready and found some M6x12 or M6x13 washers that will cure this problem, had to order the washers by the 100 so for $5 it will be worth it. If anyone needs washers I will have plenty, that is if they work. I will test them next week.

I have been using the m6x20 bolt for about three weeks now with no trouble. I have inspected a few of the align spindle bolts and most of them were not ideal as far as tolerance. I won't go back to the align bolts, its not worth my heli.

I have had my 700 since the first batch of original kits. Never had a spindle bolt break, no problems with anything actually, and I am not easy on my machine doing hard 3d. I did replace the links as they eventually wore out and also replaced the swashplate as it developed some play.

Looks like there might be some validity to some of the other threads concerning the bolts. I don't know how pressing the issues actually is though. If you've read some of the threads, some of the posters are a bit too dramatic about the problem. Just take it more as a warning and not as much as an inevitable event. As far as i'm concerned there hasn't been enough evidence to suggest that this is more than just a few helis out of thousands that have had this happen. No one in these treads have said if this has happened more than one time to the same helicopter. There are alot of factors that may not have been addressed that could have caused or magnified the instance that caused the breakage.

I think you should simply be aware of the issue. Check that area regularly for anything that might be suspicsious. I've owned my 700 for almost 2 years now and never had any problems with the spindle or the bolts or any part of the heli for that matter. I'm heavy on tic tocs, pitch pop stops, and abrupt manueavers. My headspeed is usually around 1950-2050.

It might be a good idea if you are getting a play in the grip assembly to check it a little bit closer. It coould be a sign that this could be situation that you could have on your hands at some point or another. If you can't get the play out of that assembly don't fly it, just buy a another set of bolts and a another spindle.

Not to say that it couldn't happen, but so far so good.

Well, when I took mine apart I had one bolt straight and the other had a wobble so there is something going on, more like a bad batch of bolts or something. Anyway Iam going to do like most other heli's and go with the M6x20 hex bolt with M6x13mm washer with 2.5mm thickness. Its not the cost of the heli Iam worried about, the danger of a blade flying off worries me more. Thanks all!!
