430L motor fix

[rennster]

Does anyone know if the shaft can be replaced? I took mine apart to investigate some side-to-side palcy and noticed that the shaft was smaller in diameter in the area where the bearing sits. I think it has worn as I heard of other people's experiences of the shaft spinning in the bearing race.

Align's Taiwan web site does show they sell the armature with shaft but I know you cant get them here in the US from Align RC USA.... You maybe can order from an overseas supplier?

Hey Bob, were did you find screws that small in self tapping? We have a specialty hardware store with some screws-washers-nuts small enough for ball links. But not self tapping. I could pin it, but like the screw idea better.
Update
Found these, I went to a trophy shop were they used tiny screws for mounting plates on trophies. :cool:

I am just going to have to take a chance on my 430L in a mx400 pro with extended boom and 325 blades. I was going to pin it but I have doubts that I would be able to pin it properly anyway and certainly it would ruin the warranty. I wonder how many people have never had any problems with the gold end caps. I would hope that a majority of motors are working just fine right? If a big number of the motors failed wouldn't Align recall them?

The motor runs pretty cool with my Jazz setup so hopefully that will help keep the glue from breaking free.

The gold end motors usually come apart in a crash but I have seen some come apart in flight.

I'd pin it or have someone do it for you. I thought I could get away with glueing it but even that didn't work. My endcaps slowly worked themselves out of the can and I was losing power; I thought it was my batteries but I nocied the motor slipping out of my frame. It's not that hard. Use a 1/8" bit and drilla hole as close as you can onear the ends of the motor; making sure you drill through the endcaps and put a pin or screw into it. Simple.
OR
Buy the newer version silver endcapped one. :D

Is there something different about RC Helicopter manufacturers than other consumer manufacturers? If there was a known issue with a product I would not hesitate to send it back to the company. Why doesn't everyone do that instead of just accepting that it could happen and fixing it themselves? Certainly this could just promote more bad designs down the road if the manufacturer does not have to warranty the products when they fail on the trex450. They might not even know about it or how bad the problem is because everyone fixes it themselves.

I am just really confused... If this is such a serious problem as everyone here is making out to be and lives and helicopters are at risk because of this design flaw then why isn't Align recalling them?

The only thing that makes sense to me is that maybe a small percentage fail(just like any other product) and the most vocal people are the ones with problems(1 - 2 %).

I am just trying to understand the reasoning of fixing a product myself if it has a known manufacturer defect. I would rather send it back to align so they can make sure it does not fail in the future and still be under warranty. If this is such a big problem then certainly Align would take responsibility for it wouldn't they? Is there an official ruling on this from Align somewhere that I have missed?

You are sure asking the same questions about the Align defects I have read of -and wondered about.

Thats a good point static. Being a tinkerer myself, I try to fix the problem myself and I think that is the nature of our problem.
But after fixing it and finding that the motor shaft was worn, I don't think Heliproz would take it back.

Well... a good company is one that stands behind the product that they sell. Enuff said.

The swash really caught my attention, ESC on XL did have Heatsink installed under the shrink with a pad (Not sure if thermal conductive). Motor I did as preventative measure. Glad I found info on this, but seeing little response from reps on issues.
The SP I ordered an upgrade to be safe..

I went back on SE and checked everything b4 flying.

[myrddin]

thank you for this post, I had a gold cap motor and the screws (with a little super glue) took care of it.

:)

[rennster]

LIfe span of the silver 430L motors? I ordered a silver one to replace my heavy Himax 2815-3000.

[Finless]

Been flying one since they came out (I guess about a year) with no problems.

Thanks Finless

Your local hobby shop may stock some tiny brass machine screws that Sig manufacturing sells. I found some 1/72 by 1/8" filister head screws that work great for this fix. Bonus, they look great with the gold anodized end caps! Thanks for the heads up on this problem, Finless. Later, John.

[rennster]

Do you need to fix the 4050 kV gold end motors as well? I know the 3550 kV needs fixing from experience :shock:

[Radfordian1]

I'm hoping I don't have to do this, I have a heat sink to keep it cool and a CNC main gear to reduce lateral stress on the end cap and bearings. several hours on it now, no signs of coming apart. Hope it never does!!! Anyone care to comment, or is this a must do for all 430l gold capped motors?

[Finless]

I would do it myself if you have a gold capped motor!

Bob

[Radfordian1]

OK Finless, I wont be lazy, I will do it.
Thanks for the advise :D

[shaggybirdman]

how many pole armature is in the 430L? more poles makes for a smoother motor correct?

[Radfordian1]

The 430l is a 6 pole motor here is the link with Align's specs. More poles equals more power and higher efficiency.

i just got my cde kit with a 430 motor with silver ends, but i don't see anything resembling pins, or screws. if it is pinned where are the pins?

another thing. where is the advanced post button so i could add a pic of the motor showing no pins/screws?

[shaggybirdman]

never mind i'm stupid lol. found it. i've been using the quick reply. sometimes i wonder about me. lol
