Hey Can u tell if a feathering shaft is bent without taking it apart. I can tell my main shaft is bent but can't tell if feathering shaft is also or should I just assume that it probably is.

Yea, a bent feathering shaft is a good bet.
stick one of the hex wrenches that came with the kit into the shaft bolt and spin it from one side and watch the other blade grip. If the other one wobbles around, it's bent.

What he said.................my feather shaft bends if I look at it wrong, wanna find something stronger but it will only create problems elsewhere and if you read my tip its very easy to replace.
plus its less than 5 bucks for two.

Anyone have the exact dimensions of the B400 feathering spindle -- or the ability to measure one. I don't have one handy at the moment, but came across this (http://www.helidirect.com/product_info.php?products_id=1204).

outside diameter 2.98mm (3mm) for you Americans out there 0.117"
inside diameter 1.8mm (0.0705")
length 38mm (1.5")
unsure about thread
hmmmm trex v2 feather shaft (4mm) is uber strong, but you need to change your head, that was part of the reason I went CNC, as Lock suggests look at it wrong and its bent.

But the align non-v2 will work right.

Dang, those HDX ones are 3mm x 42.20mm. 4.2mm is a bit too much to shim. :thumbdown:
Thanks for the measurement, Mon_t.

of course you could use a dremel and grind em down . . .

I got tired of trying to straighten bent feathering shafts (LHS has none, still) so I bought the Align 450 ones which are 0.070" too long. I took off 0.035" off each side in order to keep the threaded holes the same. I did it with a small lathe and calipers but it can easily be done with a Dremel and calipers as someone else suggested. I actually picked up my calipers for $20 at Autozone one day. Good deal. Digital.

the dude at my lhs said align shafts would work with both the included spacers. I have also seen other threads about this. what is the reason all these new feather shaft threads? will the align shaft work or not?
I have searched, but there seems to be new threads like every day. Perhaps there should be sticky thread about these shafts.:bomb:

The prob is, anything you do wrong they bend and Horizon has them on backorder.

lock, are u referring to eflites shafts or align shafts. i have already purchased align shafts according to sparx in a previous thread. this method will work correct??

I have no experience with align shafts but I would guess all feather shafts will bend easily they are made that way to protect other parts.

The shafts work, I am running on in my heli now. I used a dremel to shorten mine some.

If you use the both spacers it is slightly undersized and just one it is slightly oversized (vs the E-flite stock shaft) so I just cut them to be the correct length. Not sure if that helps and if anyone else has info....chime in.

Somebody else mentioned that the shaft can be straightened. I tried it with a flat-faced hammer on the back of a vise (big, heavy vise), and it straightened out very nicely. Three taps and she was straight. Hold it with a flybar screwed in one end.
I broke a spindle yesterday in a rather weird crash. The spindle broke and I lost the shims, etc. Question is: where can I get some shims?? All the other parts are listed, but the shims are not. I have the hardware kit and they are not included.
I need the Jesus bolt and mainshaft bolt. They come in the hardware package and I have already used them. Do we have to buy the whole package just to get the bolts?

I have the stock feathering shaft in now but only because my LHS finally had some. For a while I used the Align shaft but had to use some extra 0-rings to take up the spacing gap due to the fact that they are longer than the E-flite ones. The Align shaft has a few crashes on it and is still straight so i'm keeping it as a back up. They are made of stainless steel I believe and are a bit more rugged. Overall I am beginning to think that the Align products hold up a bit better during crashes but they are also more costly to replace once they do break.

Not sure about the bolts - but as for the shims - just go to LHS and get a pack of cp pro shims think there are 8 in the pack and they are the exact same as the B400

Thanks, LockMD, that solves one problem. :thumbup: Now I can figure out what to do about the bolts.

A local guy here said he was buying a pack of 50 for like 7 bucks, I never asked where he bought them. I too like you got the whole misc assembly pack so I am curious too.....
Edit: I just sent him a PM will report back on the bolts when I find anything out.

When I went to lunch I went by a "fasteners" wholesaler here in town since I knew the size (M2), and they had them. I got 12 for $4. Not cheap, but less than paying S&H, etc. This wholesaler sells in large quantities only -- but I had a friend there that accidently tore open a pack while we were looking:roll:at them -- soooo, it was kind of a bribe more than anything. They are M2X16. Good ole Dremel will make them any size less than 16mm.
If you need some, I will send you a few of mine. No problem.
