Hi HD,

Actualy RC diesel engines have been around for a very long time. There are still many offerings out in the market. The nice thing about diesels is they will swing a way bigger prop than there same size glow counterpart. Once you learn the nuances of running a diesel they are a simpler and more powerfull way to go over glow engines. All you need to run one is a can of fuel and nothing else.
