Howdy all, firstly happy Australia Day for us Aussies..... the east coast of QLD is dealing with the left overs of a tropical cyclone and we are expecing 500-700mm of rain over the next few days so no flying this long weekend.
Thought Iwould post this as some of you might gets a heads up or not be aware of this information. It's regarding the tail grip bearings on the align 450 and most clones that have directly copied the Align design. Basically there is a design flaw that may arise and it's not only a safety issue it will cause your heli to fall form the sky.
Now with me being all safety conscious and all I've delt with the issue by replacing (on order at the momnet) the tail grips and bearings on both my 450 pro's.
The issue -> if you checkout the image below which I found somewhere you'll see that the tail grip has two bearings with a brass spacer and the screw that holds the grip on. So basically the only thing that's holding the grip on is the outer case of the bearing. If this bearing fails and seperates then your grip is going to be ejected and that's one little sucker you don't want to get hit with. You'll see the inner sleeve of the bearing and the screw are still attached and the outer bearing and grip are gonskey.
The solution to this is quite obvious and that's to have a thrust bearing setup just like you have with the main blade grips. Tarot have has this available in the tail for a while now and is what is going on mine when they arrive next week.
Funny enough Align have just announced their thrust bearing upgraded tail.
So for those that have the old design, then replacing your tail grip bearings on a regular basis is mandatory. Another good tip also is to never stand directly behind your heli when you spool it up on the ground...always have the tail off at an angle so if something like the tail grip does seperate it's not going kill you.
Here are the pics of a failed bearing, the Tarot thrust tail and the new Align thrust tail.
