If you don't like tinkering with your airplane at the field, then run as fast as you can away from nitro ducted fan!! We used to spend all day sometimes just to get one successful run! And, without an in-flight mixture control you would get lean halfway through your flight amd dead stick. Make sure you have lots and lots of glow plugs because those motors are notorious for burning them up. And we haven't even begun to discuss the proper ammount of nitro and oil in your fuel yet, that can be a thread all on it's own.
If you want fuel and fly ease, buy a turbine or electric ducted fan.
Not trying to discourage you, just want you to be able to make an educated decision.
Good luck!
