Could some one please tell me what are the mechanical specifications for the two bearings that are being used on the upper blade of the mainshaft and on the bottom near the maingear?

On a very calm wind condition yesterday, I tried to see how high my x-rotation can climb. Once it reached 20FT plus, it still kept climbing, so I just hovered at that altitude for a minute or two until I accidentially reduced the throttle.

This heli dropped down from the sky like the 1929 stock market[X(][X(][X(]. It hit some branches of the tree before dropping to the ground. I was glad it didn't break any parts. Today when I flew it again, it started wobbling and the lower blades struck the upper blades and crashed and one of the lower blades snapped off and the bearings had been damaged from the crash.

Thanks,

It seems nobody had a clue what the mechanical specs of the bearings are for the x-rotation helicopter. I ordered the smallest bearing, 2.5 x 6mm but they're still too big to fit in. Are there any other places carry some bearings with specs smaller than 2.5 x6? I'm thinking of getting another x-rotation heli, and use the old one for spares.

Thanks,

There's a used x-rotation on ebay, item #5937314976. All these mirco helis whether they're used or new are the same. Get a used one for spare parts is ok if you like this type of heli just in case. You never know what parts you're going to need. If you order just the parts you need everytime you crash, eventually it'll cost you close to getting a new one or more.

Check the older posts in this forum. Some one had a problem with x-rotation heli and needed a replacement part. The post has a link to spare parts for it.

Ooo, ooo.... I know the answer!!! [8D]

I had the same problem and found some in the States and bought a few. I have several of them but you'd probably be better off getting them locally especially if you live in the USA.
