According to Gasper you can use diesel no problem.

See the thread in the Merlin Turbine Clinic "Diesel vs Kerosene".

When I first got my VT80 I used diesel just for the convenience of getting it from the fuel station. But I changed to paraffin as diesel smells quite badly and the wife was not amused.
It's more expensive than diesel but I don't fly that much so it's OK.
