Prop Balancer?

[Rich]

I don't think the aluminum hubs themselves are out of balance.

But the blades on the Solo are wide enough near the hub that a difference in plastic density either in the blade itself, or in the plastic portion of the hub can both combine to cause an imbalance.

So perhaps sanding the wide part of the heavier blade will help. People do need to be careful with sanding the hub itself so as not to cause to weaken too much.

It's the rod, not the hub. The rod is not perfectly straight. It's happened to me.

Personally I have never balanced a prop, but looking at the implements for the process - the rod. Are they marked in some way to indicated a common imbalance point, like as described - bent rod. The test is only as good as the tools used to perform the test. Just talking out loud.....

Thanks.
I no longer have a balancer/accelerometer so I'll try to borrow one to see how many Gs my static balancing provides. This might be a few weeks/months but is an interesting point. After all we don't like the camera jittering and I received my Duro-sheet yesterday

What is the purpose of Duro-sheet in prop balancing?

Has anyone braved ordering their prop balancer direct from china? A knock off brand.

Seems like a great price at $32 CDN but I wonder if they work properly.

Has anyone used one of these? Looks like the Dubro 499

Whichever you go with (I like the dubro), you'll also have to get a balance rod for the 3dr self tightening props, like this: http://www.amazon.com/EJH-Precision...F8&qid=1458323663&sr=1-1&keywords=3dr+balance

I really hope you don't end up purchasing that stolen copy that the Chinese are selling. It's obvious they 100% stole/copied Dubros work.

They won't ship that one to Canada. Is this one by dubro the same size?

I can't find the spec on the link you sent me. Just says it's for 3dr solo. Is 6mm the correct size?

 

[PdxSteve]

I'm sorry I don't know the thread size.

 

[RichWest]

The threading is supposed to be 6mm... Didn't know Dubro themselves made a threaded adapter....

I bought this one (it reads 6mm) and in description it says 3DR Solo so 6mm must be the correct size, I've already used it and the rod fits the props :
