Trex 600 XN clutch
Anyone one else having an issue with the clutch not engaging?

At first I thought maybe the motor was running backwards, but eventually it would slowly start to engage but at high rpm.

Don’t know if it’s the clutch or liner and not looking forward to taking the engine back out.

My guess would be that the gap between the clutch and liner is excessive. If left in that condition the clutch will most likely break down the road ....Been there, done that and old enough to know better.....

Jeepers I thought surely Align has sorted the issue out with the 600 size clutch liner by now,for years there has been a problem with the liner being to thin, most use the 700 size liner in the 600.

Yes the clutch gap is too big. There is a guy here in the UK who machines out the horrid steel liner and inserts a much better quality liner with the correct gap, he will even balance the clutch for you. He is on FB on Nitro Nation, put a post on there and he will reply.60% of the time, it works every time!

This is sad, but I guess that I am glad that I have access to a lathe and can do the same thing when I get back in to flying

I assembled a 700XN kit this year. It was my first Align. I found the clutch gap unacceptably large and re-lined the clutch bell. The OEM gap was twice what I would have expected.

This is my first Align experience but others tell me these types of clearances are typical for Align. I've also been told Align has a reputation for breaking clutches. I haven't experienced that but it wouldn't surprise me with .016" per side.

With Align's resources and experience I'm not sure why they continue this practice. They must believe they have the clearance right even if I don't agree.

More parts sold is why.

Prior to the "Align Revolution" the same was true with the TT Raptors......
We routinely machined out the original liners prior to building the helis and installed our own liners using Garlock 3000 gasket material and then machined the liner to the proper gap...... no more broken clutches !

Been there, done that and old enough to know better.....

I'm sure you remember - X-Cell clutch liners came as a one-piece, pre-shaped piece of what looked like wood. Early liners didn't even have a slot to allow for size adjustment. No matter. They were all made to be installed with an interference fit and had to be sized for proper clearance. It was some 30 years ago that I decided about .008" was right for my models.

That is why it surprises me that Align hasn't got this right. This is a solved problem. The answer has been know for at least 3 decades. Align is capable of making the clutch gap whatever is required but somehow believes .032" is the right number. Someone there must believe .016" is OK. I just can't figure out why.

So the clutch material on the bell is made of steel, how does that work if one needs to replace the liner? on other posts there is overheating issues and motors reving to high before engaging.

I think there are two possibilities to the first part of your question. You can either buy a new pre-lined clutch bell with a new steel liner already installed or you can re-line the old liner with traditional, i.e. non-steel, liner.

The second question about over heating... Our glow engines don't build heat with revving. They will mechanically fail but they won't overheat from increased RPM. More likely, the clutch will overheat if the engine is allowed to rev sufficiently before engaging- but the engine won't.

I read its the steel liner that is causing the problem in the first place,the use of a lathe and the standard material liner is suppose to be the cure for the 600 and 700XN, is that correct? I was referring to melted gearboxes due to the heat from the bell.

Hmmm... I don't know of a problem with gearboxes melting. I never really gave the steel liner a fair try. I relined mine after two flights. I now have 70 flights on my 700XN without an issue. Are others having problems?

Did you happen to check the gap clearance measurement between the liner and clutch?

Basically what you need for a gap is a total of .020" difference between the outside diameter of the clutch shoe disk and the inside diameter of the clutch bell housing including the liner. That will provide for the most "happiness". This amounts to .010" on each side."Sweet dreams and flying machines in pieces on the ground." J. Taylor

Is that .020 being 2mm? resulting in 1mm each side.
