Surely there is a benefit of "no Fire ball" when a model crashes when running on diesel? i know its not something that one factors in when flying models, but id rather get back a smashed mess then a pile of ash.
Has anyone ever seen a fire from a model that crashed running on diesel?

This is the first time I have heard that diesel is less volatile than kero / jet A?? Its probably just luck because all three have the same auto ignition flash point. I stay away from diesel because it is very oily and smells more than kero. Not easy to clean up when spilled.

It may be the extra oil in diesel that makes it less volatile, but it is less likely to burn in a crash.
Diesel has 97% less sulfur than Jet A, so your turbine will run cleaner on diesel.
Jet A has additives that are very harmful to humans and the environment. Either getting Jet A on your skin or breathing the exhaust. Damage to the liver, decreased immune response, impaired performance on neurological function tests and impaired hearing.

Since space is usually at a premium inside jets, It would make sense to put more energy in the same amount of space. You will get more power and or longer flight times. You can do that with diesel. But nothing is free, you pay an increased weight penalty with diesel.

But I think it was started by smashed lipos rather than the fuel itself

On our test benches both US and in Taiwan, Diesel yielded up to 5% higher thrust, while up to 10% less in consumption.
If you mustn't use Diesel, please consider Kero rather than Jet A. Dirk, Vera and myself don't tolerate the stench of Jet A well. Also, make sure you do not use contaminated Jet A from fuel dumps, many engine running problems corrected by switching to Diesel, Kero or pump Jet A.

Besides, I make up more than that cost by getting my oil from oil-store.com...

Diesel is just as capable of making a fire ball as any other fuel, if the crash conditions are right, and the ruptured fuel tank causes a fuel mist followed by an ignition source, game over - Fire ball.

I used to burn Jet-A until the EPA told all the FBO's in the USA that they were not to sell aviation fuel over the counter going after the folks who used Avgas in cars, snowmobiles, jet ski's and such. The notice didn't say just gas so they won't sell you Jet-A anymore.
I never wanted to run diesel as it smells pretty strong and as mentioned, it's damn hard to clean up (I have a diesel powered car and a diesel powered pickup) and watching the guys I know now who use diesel in their model turbines, I don't care for the black smoke either.
Enter Kerosene which is available around here from some of the bulk plants. I like it a bunch better. It's the least offensive smell of either Jet-A, which I didn't realize how bad it stunk until I started with the Kerosene, or diesel. I just take my five gallon jugs down there and mix the turbine oil in as they get filled up.

Sorry if the question has been asked before but what's Jetcat's policy on using diesel?
The engine is a gas start P-60. Warranty is not an issue, that's long gone!
Experiences of others?
Thanks, John.

I run pump K1 kero as well because it is clean, consistent and almost no odor. Diesel stinks and the quality in my area varies station to station and even at different times of the year. Also have to figure in diesel making your pump work harder as Gaspar points out in this old but very informative thread...

We running our turbines on diesel, until this saturday the run time of our 7 engines are 210 hs, 2 jetcats back from service ( after 50 hs on P80se and 28 on p140rx ) without any problem or damage or cocking, all bearings, ngv, turbine and combustion chamber, absolutely clean.
the engines has more power, and starts fast ( litle bit more seconds than jeta on fuel ramp ), fuel comsuption same or less than jeta.
but, after many hours running the engines i mixed 70/30 ( diesel / jeta ), less smoke.
4% oil mix ( today mobil dte 32 ).
i have pics of my bearings after 50 hs. In one word : perfects!!
