I would say it's fine to fly if it's running ok in idle, because I'm sure you'll have a lot of throttle in it when you get your plane airborne. But I'm probably not your most reliable source, so I would contact Jetcat and ask them.

Popping at idle is caused by usually only one of the fuel distribution tubes (Hypodermic size) being slightly misaligned.
The combustion can has a series of vaporization tubes running fore to aft, radially around the diameter of the combustion chamber. The fuel delivery tubes (some call them fuel sticks, although a stick by definition is not hollow), pass through the vaporization tubes. The fuel is supposed to be vaporized before being ignited as a gas. In your engine, one or more of the hypodermic sized tubes is very slightly misaligned, causing the fuel to leave the tube as a liquid. The "popping" is the sound of liquid fuel igniting.
No harm, no foul. It will not cause any damage to your engine.......add a fe clicks of throttle, the heat comes up, all of the fuel is then vaporized and off you go.

Hope this helps.
