Status: offline 		Could someone please give me some info on the Jetcat Turboprop. I am particularly interested in the exhaust installation.

The pictures on the Jetcat website show the exhaust as being 2 short stubs to which, I assume, extensions need to be attached. Would these extensions be welded on?

I believe the CARF Marchetti uses a version of the turbine with a single exhaust outlet at the bottom. If the engine is installed in this configuration is it a big, expensive, job to have it re-configured to the twin side exhausts?

In essence I am trying to find out how difficult it would be to move this engine into a different airframe. It is pretty expensive and, if I bought one, I wouldn't want to have it restricted to the same airframe for its whole life.

What I haven't seen in their website is a kit for the exhaust extensions, but I guess you can always ask for them to your local CARF dealer.

By the way..... the bottom exhaust solutions looks ugly to me. It should have been through the sides like the Tucano.

You would have to send the turbo prop back to JC for change if you went for a conventional set up

As you can see, the model SF-260 uses two exhaust stacks. They are pre bent and simply slip over the engine exhaust housing and then a few bolts hold the stacks in place.

If you want to put the engine in a different plane, it is no big deal. Just buy a new set of exhaust pipes for the new plane and bolt them on to the engine.

The full scale Petrol and Turboprop versions uses two exhaust stacks in the same place the TP model uses FWIW...

Have you seen the Marchetti installation? As Dave suggests, I'm not sure it is a simple as that as I believe that the exhaust outlet on the engine itself is different for the Marchetti than say, for instance, the C-ARF Tucano.

I've emailed Jetcat for some more info (including the price to swap the manifold part if required) to see if it is a sensible option.

The pictures below show the marine and the turboprop version to show the difference. I'm led to believe that the Marchetti Turboprop has something similar to the marine setup.

Let me know what you find out. A simple "S" bend with the top being turned 90 degrees would work well I suppose to have scale pipes.

Interesting...

Apparently the exhaust doesn't appear to be available from CARF yet, which is a bit odd considering you can already buy the kit.

Jetcat haven't got back to me yet which is a bit odd for them as they're usually very quick at responding to emails.

It's a development from Martin Lambert meant to power a Trex 500 helicopter. Look at it as an experiment rather then a prototype. I know Martin was talking about a version with a power turbine like most other turboprop solutions on the market too. I guess time will tell
