Hello Pazzi,

 The Pro.70BX likes to be rich to start. Make sure your needles are adjusted correctly and that your glow plug and glow driver are in good working order and that your carb is not closed all the way. There should be a small gap between the carb body and the slide barrel.

 These engines only need a few things to run... Fuel, air, ignition and compression. The first three being most important to run at all and the compression needed for reliable tuning and idle. Make sure you are using a high quality helicopter fuel with 30% nitro content.

Hope that helps.
