COST is for me 2.10 for Kero a litre or 1.6 for Diesel a litre. Less oil with Diesel less cost. 20 litres used each flying session once a week. You add it up over a year and see what you save.

Kingtech runs reliable on Diesel for me. 140F and 170G run perfectly. You can swap between if you wish if you can get some cheaper kero or Jet A1 (free). The big purple machine wont allow you to do that.

Smell don't notice it.

Smoke on shutdown, doesn't worry me.

COST and COST

If I bought another turbine it would have to be able to run on DIESEL. Kero is refined Diesle.
