Does anyone know what the difference in the two shafts is?

Since the hardened shaft for the 400 is ~$31 and the 500 is ~$14. Why such a big price difference? They're both 10mm dia...???

The hardened shafts should be the same. You may be looking at two different shafts

Yes, they are two different shafts...that is the question...what is the difference?
Why couldn't I use the $14 one in place of the $31 one?
Same shaft dia., same holes, only thing is the 500 shaft may be longer...I think I'll order one and find out...I know lots of guys that might be in need of a shaft one day

Yeah, without an actual picture of the shafts and limited description, it is hard to tell what is what.

It's nothing a call to ReadyHeli can't solve. Just pick up the phone and ask.

Shaft difference
Hi Guys, this is Rich from Readyheli, although I cannot explain the price difference as that is governed by Mikado I have looked at both shafts and can tell you this; MIK4180 is 181mm long and has a bolt hole at the very end of both sides with the snap ring groove above the lower hole. MIK4075 is 208mm long and has the top bolt hole at the very end and the lower hole is 21mm from the bottom of the shaft with the snap ring groove at the very bottom of the shaft. Hope that clears it up a little.

It depends. If it's a flybared model and an early kit, then it would take MIK2740. Later flybared kits take MIK4180 as do all the vbar versions. MIK 4075 is not for the 400. Too long.

Thats what I finally deducted, it is too long. However, it's nothing a quick turn on a lathe can't fix, especially for half the price.

Well heck, ya got a lathe then no problem.
Well, except for the upper hole though. Or you can cut it off the bottom and cut a new snap grove. You,ll need a good carbide bit for that.

They are soft and cause one way issues in short order. I would just get the original.

You know...Helidirect is great, I do most of my business there. But I'd feel foolish to ever recommend those...unless you were only doing light duty flying.

I did this video a few years ago. This was a cheap harbor freight drill and it made it through the Helidirect "hardened" shaft like it was butter. The Mikado shaft just got a scratch and the bit lost.

I have to admit the $31 shaft is a nice piece.

Guess I'll just have to quit crashing it

Or quit worrying about the cost of one stupid shaft, I just don't understand what makes the shaft for the 400 so valuable.

Probably a supply and demand thing. A lot more 550/600's out there.

Yeah, supply and demand I'm sure is at least part of it.

I do plan to build myself a nice 500SE, maybe even 600SX, this winter.

For now though the 400 is my trainer and I'm sticking with it.
