This is probably not good for my PS2 Decapod

If I had to guess, the dogbone drive shaft. The chuffing indicates the flywheel and optical tachometer on the motor are spinning.

Cheap easy fix might be likely. PART 17 below

As a side note, a while back when I got back into 3D printing last year, I found a dogbone driveshaft OPENSCAD and edited it for making driveshafts.

https://openscad.org/

This is a great thing and I think we should have more items in the 3D printing section that are specifically OPENSCAD- AKA parametric designs- allowing the end user to customize the CAD and resulting STL.

I will say, buying a factory molded one is likely stronger than the 3D printed version, especially glass filled (meaning glass fibers injected with the plastic), however, I did use printed versions and they hold up well enough. If you need a custom drive shaft or flat out just cannot get one for the exact length and size, it may be an option to get one 3D printed.

One minute running fine……..then, after a few more times around the layout, the engine is stopped but the sound system is still “running at speed”. I suspect a drive train issue.

This is my long term workhorse, a Rail King  Pennsy Decapod that has been flawless for close to 24 years…..I purchased it new in late 2001 from our long gone local shop (Chesterfield Hobbies) and it has been a great engine over the years. It was the 1st engine I ever ran in DCS when the TIUs and remotes became available in 2002.

Any thoughts on what it might be? I’m not a repair person…….

Peter,

Please allow me to join you in the "What's up with my RK Decapod?" thread.

I have the exact opposite problem.  Even after a Engine Reset, I still do not have a chuff sound.  Everything else seems fine.

Headed back down for another round of RESETs.  Thanks, Peter, for joining your thread.  Good luck with yours.

I know this probably sounds dumb, but did you un-seat and re-seat the tether?
